06.Synthesis/NonAlias_MetaOscil/NonAlias_MetaOscil.ino
-
-
-

This example demonstrates the Meta_Oscil class.

-
/* Example using a MetaOscil to generate an alias free square wave on a sweep
-
using Mozzi sonification library.
-
-
Waveforms which are not only sines (Saw, square, triangle) are composed by a lot of harmonics which are at frequencies multiple of the fundamental frequency.
-
If the frequency of one of these harmonics is higher than half the sampling frequency (https://en.wikipedia.org/wiki/Nyquist_frequency) (MOZZI_AUDIO_RATE/2 here)
-
it will create "aliases" (https://en.wikipedia.org/wiki/Aliasing) which will sound out of tune are they not harmonically related to the fundamental.
-
The higher the pitch, the more harmonics are above the Nyquist limit and the more aliased will be present for a given waveform.
-
-
One way to avoid aliases is to use "band-limited" waveforms which have a limited sets of harmonics in order to avoid them to reach the Nyquist limit.
-
As these waveforms are band-limited they will sound less "crunchy" if they are used at frequencies lower than what they are meant to be because they
-
lack the high frequency contents.
-
-
In order to paliate that, a common technique is to "swap" wave tables on the fly in order to keep the frequency content up to the Nyquist frequency but
-
not above. This is the principal usage of MetaOscil.
-
-
MetaOscil can be used (after construction) as a proper Oscil but really is a bunch of oscillators with only one playing.
-
It will switch between different oscils seemlessly depending on the asked frequency. This allows to switch between oscillators with less
-
and less harmonics as the pitch goes up, in order to avoid aliases, which is demonstrated by this example.
-
-
The bandlimited tables are nammed according to the max frequency they can play without bringing aliases at a given frequency. For example:
-
square_max_90_at_16384_512_int8.h ensures that no aliases will be present up to 90Hz at 16384Hz sampling rate (the default for Arduino).
-
If your sampling rate is higher (say 32768 which is the default for most 32bits platforms) this table will be able to play up to
-
180=90*2Hz without aliases, as the Nyquist frequency is two times higher.

-
-

This example demonstrates the Sample class.

-
/*
-
Example playing samples encoded with Huffman compression.
-
-
Demonstrates the SampleHuffman class.
-
SampleHuffman, most of this explanation, and the audio2huff.py script are adapted from "audioout",
-
an Arduino sketch by Thomas Grill, 2011 http//grrrr.org.
-
-
Huffman decoding is used on sample differentials,
-
saving 50-70% of space for 8 bit data, depending on the sample rate.
-
-
This implementation just plays back one sample each time next() is called, with no
-
speed or other adjustments. It's slow, so it's likely you will only be able to play one sound at a time.
-
-
Audio data, Huffman decoder table, sample rate and bit depth are defined
-
in a sounddata.h header file. This file can be generated for a sound file with the
-
accompanying Python script audio2huff.py, in Mozzi/extras/python/
-
-
Invoke with:
-
python audio2huff.py --sndfile=arduinosnd.wav --hdrfile=sounddata.h --bits=8 --name=soundtablename
-
-
You can resample and dither your audio file with SOX,
-
e.g. to 8 bits depth @ Mozzi's 16384 Hz sample rate:
-
sox fullglory.wav -b 8 -r 16384 arduinosnd.wav
-
-
Alternatively you can export a sound from Audacity, which seems to have less noticeable or no dithering,
-
using Project Rate 16384 Hz and these output options:
-
Other uncompressed files, Header: WAV(Microsoft), Encoding: Unsigned 8 bit PCM
-
-
The header file contains two lengthy arrays:
-
One is "SOUNDDATA" which must fit into Flash RAM (available in total: 32k for ATMega328)
-
The other is "HUFFMAN" which must also fit into Flash RAM

This example demonstrates the ReverbTank class.

-
/* Example of reverb on a synthesised sound
-
using Mozzi sonification library.
-
-
Demonstrates ReverbTank, a reverb small enough to fit on
-
the Arduino Nano, which for some reason wasn't able to fit a larger version
-
which did fit on other 328 based boards.
-
It's a pretty horrible reverb which sounds like the inside of a tin can.
-
For simplicity, ReverbTank has hardcoded maximum delay sizes
-
but also has default delay times which can be changed in the constructor
-
or by setting during run time to allow live tweaking.
-
The synthesised sound comes from the phasemod synth example.

This example demonstrates the MultiResonantFilter specification of this class.

-
/* Example of filtering a wave with different types of filters
-
using Mozzi sonification library.
-
-
Demonstrates MultiResonantFilter<uint8_t>.
-
-
MultiResonantFilter is a derivative of ResonantFilter which allows all filter types to be accessed with only one filter.
-
It behaves similarly to ResonantFilter except:
-
- next(in) does not return anything and is just used to pass the current sample to the filter. Except for special cases should probably be called only once in updateAudio()
-
- different filter outputs are accessible via low(), high(), band() and notch() functions.
-
- note that the different filter types can be called in the same updateAudio(), for eg. to get different part of the signal.

This example demonstrates the ResonantFilter16 specification of this class.

-
/* Example of filtering a wave,

-
-
Demonstrates ResonantFilter<uint16_t, FILTER_TYPE>.
-
-
ResonantFilter<uint16_t, FILTER_TYPE> is a different version of ResonantFilter<uint8_t, FILTER_TYPE> which uses bigger containing types for internal calculations.
-
The main differences with LowPassFilter are:
-
- parameters (resonance and cutoff_freq) are coded on 16bits, allowing for smoother transitions and finer tuning if needed,
-
- for 8bits platforms (like the Arduino) it will accept input samples of more than 8bits without overflowing,
-
- the drawback is higher CPU usage, especially for 8bits platform. If speed is crucial, you should probably use ResonantFilter<uint8_t, FILTER_TYPE> instead.

20 /** A simple ADSR envelope generator. This implementation has separate update() and next()
-
21 methods, where next() interpolates values between each update().
-
22 The "normal" way to use this would be with update() in updateControl(), where it calculates a new internal state each control step,
-
23 and then next() is in updateAudio(), called much more often, where it interpolates between the control values.
-
24 This also allows the ADSR updates to be made even more sparsely if desired, eg. every 3rd control update.
-
25 @tparam CONTROL_UPDATE_RATE The frequency of control updates.
-
26 Ordinarily this will be MOZZI_CONTROL_RATE, but an alternative (amongst others) is
-
27 to set this as well as the LERP_RATE parameter to MOZZI_AUDIO_RATE, and call both update() and next() in updateAudio().
-
28 Such a use would allow accurate envelopes with finer resolution of the control points than MOZZI_CONTROL_RATE.
-
29 @tparam LERP_RATE Sets how often next() will be called, to interpolate between updates set by CONTROL_UPDATE_RATE.
-
30 This will produce the smoothest results if it's set to MOZZI_AUDIO_RATE, but if you need to save processor time and your
-
31 envelope changes slowly or controls something like a filter where there may not be problems with glitchy or clicking transitions,
-
32 LERP_RATE could be set to MOZZI_CONTROL_RATE (for instance). Then update() and next() could both be called in updateControl(),
-
33 greatly reducing the amount of processing required compared to calling next() in updateAudio().
-
34 @todo Test whether using the template parameters makes any difference to speed,
-
35 and rationalise which units do and don't need them.
-
36 Template objects are messy when you try to use pointers to them,
-
37 you have to include the whole template in the pointer handling.

-
17  * @page mozzi_audio_output_architecture Basic architecture of audio generation, buffering, and output in Mozzi
-
18  *
-
19  * Mozzi provides support for audio ouput on a range of different boards and CPUs. This page is about the following related topics:
-
20  *
-
21  * - adding a custom output method (importantly using external DACs) to your sketch
-
22  * - writing sketches that will work on different platforms / with different output methods
-
23  * - extending Mozzi for a new architecture
-
24  *
-
25  * For all of these topics, it is helpful to have a basic understanding of the basic output steps in Mozzi:
-
26  *
-
27  * 1. Inside the loop() function in your sketch you call audioHook().
-
28  * 1a. If the audio output buffer is currently filled, this does nothing.
-
29  * 1b. Otherwise, this calls updateAudio(). The generated sample is then added to the audio output buffer. (Also, updateControl() will be called at an appropriate rate,
-
30  * and a few other details that are not important for this discussion.)
-
31  *
-
32  * 2. A platform-specific timer is triggered at audio rate (usually), takes a sample from the output buffer and sends it to audioOutput().
-
33  *
-
34  * 3. The audioOutput() function - usually predefined inside Mozzi - takes care of sending the sample to the hardware.
-
35  *
-
36  * These output steps are not always followed, however. Firstly, when using @ref external_audio output, the audioOutput() funtion is supplied by the user sketch,
-
37  * instead of Mozzi. @ref external_audio output.
-
38  *
-
39  * Some ports will also want to bypass the Mozzi audio output buffer. For instance, an internal DAC may be addressable via an efficient DMA-connected
-
40  * buffer, already, and also have a built-in rate control. In this case, ports will internally set the define @ref BYPASS_MOZZI_OUTPUT_BUFFER to true. Such a port will
-
41  * have to provide a custom definition of canBufferAudioOutput(), returning true, whenever a new sample of output can be accepted. No timer at audio-rate is set up in this
-
42  * case.
-
43  *
-
44  * Finally, the @ref external_audio output mode (@ref MOZZI_AUDIO_MODE MOZZI_OUTPUT_EXTERNAL_CUSTOM) is essentially a combination of the two. Here, the user sketch needs to provide
-
45  * both audioOutput() and canBufferAudioOutput(). The latter is again called from audioHook(), and whenever it returns true, a new sample is generated and passed to
-
46  * audioOutput().
-
47  *
-
48  * @section audio_shifting Platform specific audio resolution
-
49  * Different output methods often support a different resolution of output samples. To provide best performance on slow boards, Mozzi expects your updateAudio() function to
-
50  * return samples in exactly the width that is needed at the output stage. Thus, defining this naively, an updateAudio() function designed for 8 bit output will produce very
-
51  * low volume output on a 16 bit DAC, while the other way around overflows will result in way too loud and heavily distored output. Fortunately, all that is needed to write
-
52  * portable sketches is to specify how many bits your updateAudio() function provides. The (inline) functions in the AudioOutput namespace do just that. Using them makes sure
-
53  * your audio output is shifted if, and as much as needed on all platforms.
-

100  * a) To construct an output frame, you should use one of the from8Bit(), fromNBit(), etc. functions. Given a raw input value, at a known resolution (number of bits),

-

19 For example, this could be used to produce echo-like effects using multiple
-
20 instances of the same voice, when AudioDelay would be too short for an actual
-
21 audio echo. This is in fact just a wrapper of the AudioDelay code.
-
22 @tparam NUM_BUFFER_SAMPLES is the length of the delay buffer in samples. This should
-
23 be a power of two.
-
24 @tparam the type of numbers to use for the signal in the delay. The default is int8_t, but int could be useful
-
25 when adding manual feedback. When using int, the input should be limited to 15 bits width, ie. -16384 to 16383.

Detailed Description

-

This is the main include file in Mozzi.

-

Almost all sketches using Mozzi will want to include this file exactly once.

-

Should your sketch require Mozzi Core Functions Mozzi functions in more than one translation unit (i.e. you have more than one .cpp-file in your sketch itself), only one of these shall include this file, while any others shall include MozziHeadersOnly instead. (Failing to heed this advice will lead to "duplicate definition" errors.)

121 ATmega328 technical manual, Section 12.7.4:
-
122 The dual-slope operation [of phase correct pwm] has lower maximum operation
-
123 frequency than single slope operation. However, due to the symmetric feature
-
124 of the dual-slope PWM modes, these modes are preferred for motor control
-
125 applications.
-
126 Due to the single-slope operation, the operating frequency of the
-
127 fast PWM mode can be twice as high as the phase correct PWM mode that use
-
128 dual-slope operation. This high frequency makes the fast PWM mode well suited
-
129 for power regulation, rectification, and DAC applications. High frequency allows
-
130 physically small sized external components (coils, capacitors)..
-

137 250000Hz dual 12 bits, gritty, if you're gonna have 2 pins, have 14 bits

138 500000Hz dual 10 bits, grittier

71 The strategy to output sound on this platform differs somehow from what is usually done in Mozzi.
-
72 Usually, Mozzi's circular buffer are read from the outputting device (PWM, DAC...) or committed as
-
73 a whole (for the MBED platform) and thus emptied. Once a free spot is present, Mozzi fills it with updateAudio().
-
74 Here, the DAC works straight from a buffer, outputting samples from it at a fixed rate.
-
75 This is sweet as we can branch it straight to Mozzi's buffer and it will read from it without
-
76 further action from us.
-
77 The big difference is that it *does not* empty the buffer, nor notify that something has been
-
78 read, which is okay for outputting a periodic signal where just a full period is present
-
79 in the buffer.
-
80 As a consequence we need to artificially empty the buffer at the same rate that the DAC is reading
-
81 it.

26  * - So nobody on the nets seems to have quite figured out, how to run the RP2040 ADC in "regular" asynchronous mode.
-
27  * - The ADC sports an interrupt, presumably to be triggered when a conversion is done, but how to connect a callback to that?
-
28  * - There is, however, an official example on a free running ADC writing to DMA (https://github.com/raspberrypi/pico-examples/blob/master/adc/dma_capture/dma_capture.c ; BSD licensed)
-
29  * We'll abuse that to connect a callback to the DMA channel, instead.

Detailed Description

-

Template for implementation of new ports.

-

README! This file is meant to be used as a template when adding support for a new platform. Please read these instructions, first.

-

Files involved:

    -
  1. Modify hardware_defines.h, adding a macro to detect your target platform
    2. -
  2. Modify MozziGuts.cpp to include MozziGuts_impl_YOURPLATFORM.hpp
    3. -
  3. Modify internal/config_checks_generic.h to include internal/config_checks_YOURPLATFORM.h
    4. -
  4. Copy this file to MozziGuts_impl_YOURPLATFORM.hpp and adjust as necessary, same for internal/config_checks_template.h (If your platform is very similar to an existing port, it may instead be better to modify the existing MozziGuts_impl_XYZ.hpp/config_checks_XYZ.h, instead of steps 2-3.). Some platforms may need small modifications to other files as well, e.g. mozzi_pgmspace.h
    5. -
-

How to implement MozziGuts_impl_YOURPLATFORM.hpp:

    -
  • Follow the NOTEs provided in this file
    • -
  • Read the doc at the top of AudioOutput.h for a better understanding of the basic audio output framework
    • -
  • Take a peek at existing implementations for other hardware (e.g. TEENSY3/4 is rather complete while also simple at the time of this writing)
    • -
  • Wait for more documentation to arrive
    • -
  • Ask when in doubt
    • -
  • Don't forget to provide a PR when done (it does not have to be perfect; e.g. many ports skip analog input, initially)

36 /**
-
37 Oscil plays a wavetable, cycling through the table to generate an audio or
-
38 control signal. The frequency of the signal can be set or changed with
-
39 setFreq(), and the output of an Oscil can be produced with next() for a simple
-
40 cycling oscillator, or atIndex() for a particular sample in the table.
-
41 @tparam NUM_TABLE_CELLS This is defined in the table ".h" file the Oscil will be
-
42 using. It's important that it's a power of 2, and either a literal number (eg. "8192") or a
-
43 defined macro, rather than a const or int, for the Oscil to run fast enough.
-
44 @tparam UPDATE_RATE This will be MOZZI_AUDIO_RATE if the Oscil is updated in
-
45 updateAudio(), or MOZZI_CONTROL_RATE if it's updated each time updateControl() is
-
46 called. It could also be a fraction of MOZZI_CONTROL_RATE if you are doing some kind
-
47 of cyclic updating in updateControl(), for example, to spread out the processor load.
-
48 @todo Use conditional compilation to optimise setFreq() variations for different table
-
49 sizes.
-
50 @note If you #define OSCIL_DITHER_PHASE before you #include <Oscil.h>,
-
51 the phase increments will be dithered, which reduces spurious frequency spurs
-
52 in the audio output, at the cost of some extra processing and memory.

-
19  Enables the resolution of analog inputs to be increased by oversampling and decimation.
-
20  Noise should be added to the input before it's digitised, then a succession of input readings are summed and
-
21  finally divided to give a number with greater resolution than the ADC.
-
22  Often, noise in the Arduino system will be enough, but there are other practical methods described in
-
23  [Enhancing ADC Resolution by Oversampling](http://www.atmel.com/images/doc8003.pdf‎),
-
24  as well as an explanation of the overall approach.
-
25  @tparam RESOLUTION_INCREASE_BITS how many extra bits of resolution to produce.
-
26  The window length and the memory it needs increases quickly as the oversampling resolution increases.
-
27  1 bit = 4 unsigned ints (analog input between 0-1023) = 8 uint8_ts,
-
28  2 bits = 16 unsigned ints = 32 uint8_ts,
-
29  3 bits = 64 unsigned ints = 128 uint8_ts,
-
30  More than 3 bits increase in resolution would require either using longs to store the readings,
-
31  which would need 1024 uint8_ts for a 4 bit increase and 4096 uint8_ts for 5 bits (do any avr's have that much room?),
-
32  or the average reading would have to be no more than 128 (for 4 bits increase), because 256 readings would be needed,
-
33  and the sum of all 256 readings would have to fit into an int. (32767 / 256 = 128).
-
34  Changing OverSample to use unsigned ints could enable an average reading of 256, but isn't tested properly yet.
-
35  @note The higher the resolution, the more lag there will be.
-
36  It's almost a RollingAverage filter, with the difference that
-
37  OverSample doesn't divide by as much as you would for an average.

22 simple resonant filter posted to musicdsp.org by Paul Kellett
-
23 http://www.musicdsp.org/archive.php?classid=3#259, applying the
-
24 modification from Peter Schoffhauzer to make it able to output
-
25 all filter types (LowPass, HighPass, Notch and BandPass).
-
26 
-
27 The generic filter is ResonantFilter<unsigned_t type, FILTER_TYPE>.
-
28  - type specifies the type expected for the cutoff and resonance. Only uint8_t and uint16_t have been tested. These are denoted 8bits and 16bits versions of the filter in the following.
-
29  - FILTER_TYPE specifies the filter type. LOWPASS, BANDPASS, HIGHPASS and NOTCH are available types.
-
30 
-
31 Two versions are available: the 8bits and 16bits versions (see above).
-
32 The 8bits version is an optimized version that uses 8bits values to set
-
33 the resonance and the cutoff_freq. It can works on 8bits samples only
-
34 on 8bits platforms.
-
35 The 16bits version consumes more CPU ressources but uses 16bits values
-
36 for resonance and cutoff_freq and can work on samples up to 16bits on
-
37 8bits platforms and up to 32 on 32bits platforms.
-
38 
-
39 The filter can be instanciated using the template version ResonantFilter<unsigned_t type, FILTER_TYPE>. For ease of use, the following types are also accepted:
-
40 
-
41 8bits versions: LowPassFilter, HighPassFilter, BandPassFilter, NotchFilter
-
42 16bits versions: LowPassFilter16, HighPassFilter16, BandPassFilter16, NotchFilter16
-
43 
-
44 
-
45 
-
46 //// ALGORITHM ////
-
47 // set feedback amount given f and q between 0 and 1
-
48 fb = q + q/(1.0 - f);
-
49 In order to avoid a slow division we use the use a Taylor expansion to approximate 1/(1.0 - f):
-
50 Close to f=0: 1/(1.0-f) approx 1.0+f.
-
51 Hence: fb = q + q * (1.0 + f)
-
52 This approximation is less and less valid with an increasing cutoff, leading to a reduction of the resonance of the filter at high cutoff frequencies.
-
53 
-
54 // for each sample...
-
55 buf0 = buf0 + f * (in - buf0 + fb * (buf0 - buf1));
-
56 buf1 = buf1 + f * (buf0 - buf1);
-
57 out = buf1; // LowPass
-
58 out = in - buf0; // HighPass
-
59 out = buf0 - buf1; // BandPass
-
60 out = in - buf0 + buf1; // Notch

17 /** A sample player for samples encoded with Huffman compression.
-
18 
-
19 This class and the audio2huff.py script are adapted from "audioout",
-
20 an Arduino sketch by Thomas Grill, 2011 http//grrrr.org
-
21 
-
22 Huffman decoding is used on sample differentials,
-
23 saving 50-70% of space for 8 bit data, depending on the sample rate.
-
24 
-
25 This implementation just plays back one sample each time next() is called, with no
-
26 speed or other adjustments.
-
27 It's slow, so it's likely you will only be able to play one sound at a time.
-
28 
-
29 Audio data, Huffman decoder table, sample rate and bit depth are defined
-
30 in a sounddata.h header file. This file can be generated for a sound file with the
-
31 accompanying Python script audio2huff.py, in Mozzi/extras/python/
-
32 
-
33 Invoke with:
-
34 python audio2huff.py --sndfile=arduinosnd.wav --hdrfile=sounddata.h --bits=8 --name=soundtablename
-
35 
-
36 You can resample and dither your audio file with SOX,
-
37 e.g. to 8 bits depth @ Mozzi's 16384 Hz sample rate:
-
38 sox fullglory.wav -b 8 -r 16384 arduinosnd.wav
-
39 
-
40 Alternatively you can export a sound from Audacity, which seems to have less noticeable or no dithering,
-
41 using Project Rate 16384 Hz and these output options:
-
42 Other uncompressed files, Header: WAV(Microsoft), Encoding: Unsigned 8 bit PCM
-
43 
-
44 The header file contains two lengthy arrays:
-
45 One is "SOUNDDATA" which must fit into Flash RAM (available in total: 32k for ATMega328)
-
46 The other is "HUFFMAN" which must also fit into Flash RAM

18 /** A simple infinite impulse response low pass filter for smoothing control or audio signals.
-
19 This algorithm comes from http://en.wikipedia.org/wiki/Low-pass_filter:
-
20 y[i] := y[i-1] + α * (x[i] - y[i-1]),
-
21 translated as
-
22 out = last_out + a * (in - last_out).
-
23 It's not calibrated to any real-world update rate, so if you use it at
-
24 MOZZI_CONTROL_RATE and you change MOZZI_CONTROL_RATE, you'll need to adjust the smoothness
-
25 value to suit.
-
26 @tparam T the type of numbers being smoothed. Watch out for numbers overflowing the
-
27 internal calculations. Some experimentation is recommended.
-
28 @note Timing: ~5us for 16 bit types, ~1us for 8 bit types.
-
29 @todo Check if 8 bit templates can work efficiently with a higher res smoothness -
-
30  as is they don't have enough resolution to work well at audio rate. See if Line might be
-
31  more useful in most cases.

Detailed Description

-

A script for converting raw 8 bit sound data files to wavetables for Mozzi.

-

Usage: >>>char2mozzi.py <infile outfile tablename samplerate>

-
Parameters
- - - - - -
infileThe file to convert, RAW(headerless) Signed 8 bit PCM.
outfileThe file to save as output, a .h file containing a table for Mozzi.
tablenameThe name to give the table of converted data in the new file.
samplerateThe samplerate the sound was recorded at. Choose what make sense for you, if it's not a normal recorded sample.
-
-
-
Note
Using Audacity to prepare raw sound files for converting:
-

For generated waveforms like sine or sawtooth, set the project rate to the size of the wavetable you wish to create, which must be a power of two (eg. 8192), and set the selection format (beneath the editing window) to samples. Then you can generate and save 1 second of a waveform and it will fit your table length.

-

For a recorded audio sample, set the project rate to the MOZZI_AUDIO_RATE (16384 in the current version). Samples can be any length, as long as they fit in your Arduino.

-

Save by exporting with the format set to "Other uncompressed formats", "Header: RAW(headerless)" and "Encoding: Signed 8 bit PCM".

-

Now use the file you just exported, as the "infile" to convert.

Detailed Description

-

template<unsigned int CONTROL_UPDATE_RATE, unsigned int LERP_RATE, typename T = unsigned int>
-class ADSR< CONTROL_UPDATE_RATE, LERP_RATE, T >

- -

A simple ADSR envelope generator.

-

This implementation has separate update() and next() methods, where next() interpolates values between each update(). The "normal" way to use this would be with update() in updateControl(), where it calculates a new internal state each control step, and then next() is in updateAudio(), called much more often, where it interpolates between the control values. This also allows the ADSR updates to be made even more sparsely if desired, eg. every 3rd control update.

Template Parameters
- - - -
CONTROL_UPDATE_RATEThe frequency of control updates. Ordinarily this will be MOZZI_CONTROL_RATE, but an alternative (amongst others) is to set this as well as the LERP_RATE parameter to MOZZI_AUDIO_RATE, and call both update() and next() in updateAudio(). Such a use would allow accurate envelopes with finer resolution of the control points than MOZZI_CONTROL_RATE.
LERP_RATESets how often next() will be called, to interpolate between updates set by CONTROL_UPDATE_RATE. This will produce the smoothest results if it's set to MOZZI_AUDIO_RATE, but if you need to save processor time and your envelope changes slowly or controls something like a filter where there may not be problems with glitchy or clicking transitions, LERP_RATE could be set to MOZZI_CONTROL_RATE (for instance). Then update() and next() could both be called in updateControl(), greatly reducing the amount of processing required compared to calling next() in updateAudio().

-class AudioDelay< NUM_BUFFER_SAMPLES, T >

- -

Audio delay line for comb filter, flange, chorus and short echo effects.

-
Template Parameters
- - - -
NUM_BUFFER_SAMPLESis the length of the delay buffer in samples. This should be a power of two. The largest delay you'll fit in an atmega328 will be 512 cells, which at 16384 Hz sample rate is 31 milliseconds. More of a flanger or a doubler than an echo. The amount of memory available for delays on other chips will vary. AudioDelay() doesn't have feedback. If you want feedback, use AudioDelayFeedback().
thetype of numbers to use for the signal in the delay. The default is int8_t, but int could be useful when adding manual feedback. When using int, the input should be limited to 15 bits width, ie. -16384 to 16383.

Detailed Description

-

template<uint16_t NUM_BUFFER_SAMPLES, int8_t INTERP_TYPE = LINEAR, typename su = int8_t>

Audio delay line with feedback for comb filter, flange, chorus and short echo effects.

-
Template Parameters
- - - - -
NUM_BUFFER_SAMPLESis the length of the delay buffer in samples, and should be a power of two. The maximum delay length which will fit in an atmega328 is half that of a plain AudioDelay object, in this case 256 cells, or about 15 milliseconds. AudioDelayFeedback uses int16_t sized cells to accomodate the higher amplitude of direct input to the delay as well as the feedback, without losing precision. Output is only the delay line signal. If you want to mix the delay with the input, do it in your sketch. AudioDelayFeedback uses more processing and memory than a plain AudioDelay, but allows for more dramatic effects with feedback.
INTERP_TYPEa choice of LINEAR (default) or ALLPASS interpolation. LINEAR is better for sweeping delay times, ALLPASS may be better for reverb-like effects.
suthe type of numbers to use for the signal in the delay. The default is int8_t, but int16_t could be useful. Larger types (int32_t) might produce overflows as of v2.0.2.

Checks whether the capacitor has charged, and returns how long it took for the most recent charge.

This would preferably be called in updateControl(), but if the resolution isn't fine enough or the pin charges too fast for updateControl() to catch, try it in updateAudio().

Returns
the sensor value, reflected in how many checking cycles it took to charge the capacitor.

Detailed Description

-

template<unsigned int NUM_BUFFER_SAMPLES, class T = int>
-class ControlDelay< NUM_BUFFER_SAMPLES, T >

- -

Control-rate delay line for delaying control signals.

-

For example, this could be used to produce echo-like effects using multiple instances of the same voice, when AudioDelay would be too short for an actual audio echo. This is in fact just a wrapper of the AudioDelay code.

Template Parameters
- - - -
NUM_BUFFER_SAMPLESis the length of the delay buffer in samples. This should be a power of two.
thetype of numbers to use for the signal in the delay. The default is int8_t, but int could be useful when adding manual feedback. When using int, the input should be limited to 15 bits width, ie. -16384 to 16383.

Detailed Description

-

A DC-blocking filter useful for highlighting changes in control signals.

-

The output of the filter settles to 0 if the incoming signal stays constant. If the input changes, the filter output swings to track the change and eventually settles back to 0.

Exponential attack decay envelope. - More...

#include <Ead.h>

-

Detailed Description

-

Exponential attack decay envelope.

-

This produces a natural sounding envelope. It calculates a new value each time next() is called, which can be mapped to other parameters to change the amplitude or timbre of a sound.

Note
Currently doesn't work at audio rate... may need larger number types for Q8n8attack and Q8n8decay ?

Detailed Description

-

A non-blocking replacement for Arduino's delay() function.

-

EventDelay can be set() to a number of milliseconds, then after calling start(), ready() will return true when the time is up.
- Alternatively, start(milliseconds) will call set() and start() together.

Line< T > Class Template Reference

- -

For linear changes with a minimum of calculation at each step. - More...

- -

#include <Line.h>

-

Detailed Description

-

template<class T>
-class Line< T >

- -

For linear changes with a minimum of calculation at each step.

-

For instance, you can use Line to make an oscillator glide from one frequency to another, pre-calculating the required phase increments for each end and then letting your Line change the phase increment with only a simple addition at each step.

Template Parameters
- - -
Tthe type of numbers to use. For example, Line <int> myline; makes a Line which uses ints.
-
-
-
Note
Watch out for underflows in the internal calcualtion of Line() if you're not using floats (but on the other hand try to avoid lots of floats, they're too slow!). If it seems like the Line() is not working, there's a good chance you need to scale up the numbers you're using, so internal calculations don't get truncated away. Use Mozzi's fixed-point number types in mozzi_fixmath.h, which enable you to represent fractional numbers. Google "fixed point arithmetic" if this is new to you.

MetaOscil is a wrapper for several Oscil. - More...

#include <MetaOscil.h>

-

Detailed Description

-

template<uint16_t NUM_TABLE_CELLS, uint16_t UPDATE_RATE, byte N_OSCIL>
-class MetaOscil< NUM_TABLE_CELLS, UPDATE_RATE, N_OSCIL >

- -

MetaOscil is a wrapper for several Oscil.

-

Once constructed it will behave exactly as an Oscil except that it will automatically switch between Oscil depending on the asked frequency. This allows to produce non-aliased sounds by switching between tables with less and less harmonics as the frequency increases.

Detailed Description

-

A metronome class which is like an EventDelay which retriggers itself when the delay time is up, to produce a repeating beat.

-

Metronome can be set() to a number of milliseconds, then after calling start(), ready() will return true when the time is up.
- Alternatively, start(milliseconds) will call set() and start() together. This is called Metronome to avoid conflict with the Arduino Metro library.

Q16n16 Q16n16_mtof (Q16n16 midival_fractional)
- 		-friend
-
- -

Converts midi note number to frequency with speed and accuracy.

-

Q16n16_mtofLookup() is a fast alternative to (float) mtof(), and more accurate than (uint8_t) mtof(), using Q16n16 fixed-point format instead of floats or uint8_t values. Q16n16_mtof() uses cheap linear interpolation between whole midi-note frequency equivalents stored in a lookup table, so is less accurate than the float version, mtof(), for non-whole midi values.

Note
Timing: ~8 us.
-
Parameters
- - -
midival_fractionala midi note number in Q16n16 format, for fractional values.
-
-
-
Returns
the frequency represented by the input midi note number, in Q16n16 fixed point fractional integer format, where the lower word is a fractional value.

◆ randSeed [1/2]

- -
-
- - - - - -
- - - - - - - -
void randSeed ()
- 		-friend
-
- -

Initialises Mozzi's (pseudo)random number generator xorshift96(), which is used in Mozzi's rand() function.

-

This can be useful if you want random sequences to be different on each run of a sketch, by seeding with a fairly random input. randSeed() called without a parameter uses noise from reading the Arduino's internal temperature as the seed, a technique discussed at http://arduino.cc/forum/index.php/topic,38091.0.html, borrowing code put there by Rob Tillaart.

-
Note
Intialization of the random seed is done differently on different MCUs, but is nowhere near perfect for most (and for some it is not even implemented at all). Many implementations (e.g. on AVR, STM32) simply rely on reading a (hopefully noisy) internal temperature sensor. You will often get better results by calling analogRead() - not mozziAnalogRead(0), in this case! - on one or two floating (non-connected) analog pins.

void randSeed (uint32_t seed)
- 		-friend
-
- -

Initialises Mozzi's (pseudo)random number generator xorshift96(), which is used in Mozzi's rand() function.

-

This can be useful if you want random sequences to be different on each run of a sketch, by seeding with fairly random input, such as analogRead() on an unconnected pin (as explained in the Arduino documentation for randomSeed(). randSeed is the same as xorshift96Seed(), but easier to remember.

Parameters

seeda number to use as a seed.

Random number generator.

-

A faster replacement for Arduino's random function, which is too slow to use with Mozzi. Based on Marsaglia, George. (2003). Xorshift RNGs. http://www.jstatsoft.org/v08/i14/xorshift.pdf

Returns

Detailed Description

-

template<typename su = uint8_t>
-class MultiResonantFilter< su >

- -

A generic filter for audio signals that can produce lowpass, highpass, bandpass and notch outputs at runtime.

-

Behaves like ResonantFilter for setting the resonance and cutoff frequency. Like ResonantFilter, it can be used on different sample sizes: MultiResonantFilter<uint8_t> and MultiResonantFilter<uint16_t> have been tested. For the former, both cutoff and resonance are uint8_t, hence between 0-255. For the later, both cutoff and resonance are uint16_t, hence between 0-65535.

Oscil< NUM_TABLE_CELLS, UPDATE_RATE > Class Template Reference
-
-
- -

Oscil plays a wavetable, cycling through the table to generate an audio or control signal. - More...

- -

#include <Oscil.h>

-

Detailed Description

-

template<uint16_t NUM_TABLE_CELLS, uint16_t UPDATE_RATE>
-class Oscil< NUM_TABLE_CELLS, UPDATE_RATE >

- -

Oscil plays a wavetable, cycling through the table to generate an audio or control signal.

-

The frequency of the signal can be set or changed with setFreq(), and the output of an Oscil can be produced with next() for a simple cycling oscillator, or atIndex() for a particular sample in the table.

Template Parameters
- - - -
NUM_TABLE_CELLSThis is defined in the table ".h" file the Oscil will be using. It's important that it's a power of 2, and either a literal number (eg. "8192") or a defined macro, rather than a const or int, for the Oscil to run fast enough.
UPDATE_RATEThis will be MOZZI_AUDIO_RATE if the Oscil is updated in updateAudio(), or MOZZI_CONTROL_RATE if it's updated each time updateControl() is called. It could also be a fraction of MOZZI_CONTROL_RATE if you are doing some kind of cyclic updating in updateControl(), for example, to spread out the processor load.
-
-
-
Note
If you #define OSCIL_DITHER_PHASE before you #include <Oscil.h>, the phase increments will be dithered, which reduces spurious frequency spurs in the audio output, at the cost of some extra processing and memory.

uint32_t Oscil< NUM_TABLE_CELLS, UPDATE_RATE >::phaseIncFromFreq (int frequency)
- 		-inline
-
- -

phaseIncFromFreq() and setPhaseInc() are for saving processor time when sliding between frequencies.

-

Instead of recalculating the phase increment for each frequency in between, you can just calculate the phase increment for each end frequency with phaseIncFromFreq(), then use a Line to interpolate on the fly and use setPhaseInc() to set the phase increment at each step. (Note: I should really profile this with the oscilloscope to see if it's worth the extra confusion!)

Parameters
- - -
frequencyfor which you want to calculate a phase increment value.
-
-
-
Returns
the phase increment value which will produce a given frequency.

- - - - - - - - -
void Oscil< NUM_TABLE_CELLS, UPDATE_RATE >::setFreq (float frequency)
- 		-inline
-
- -

Set the oscillator frequency with a float.

-

Using a float is the most reliable way to set frequencies, -Might- be slower than using an int but you need either this, setFreq_Q24n8() or setFreq_Q16n16() for fractional frequencies.

Parameters
- - -
frequencyto play the wave table.

- - - - - - - - -
void Oscil< NUM_TABLE_CELLS, UPDATE_RATE >::setFreq (int frequency)
- 		-inline
-
- -

Set the oscillator frequency with an unsigned int.

-

This is faster than using a float, so it's useful when processor time is tight, but it can be tricky with low and high frequencies, depending on the size of the wavetable being used. If you're not getting the results you expect, try explicitly using a float, or try setFreq_Q24n8() or or setFreq_Q16n16().

Parameters

frequencyto play the wave table.

void Oscil< NUM_TABLE_CELLS, UPDATE_RATE >::setFreq (SFix< NI, NF, RANGE > frequency)

-
- -

Set the frequency using SFix<NI,NF> fixed-point number format.

-

This falls back to using UFix<16,16> internally and is provided as a fallout for other UFix types. If possible try to use directly UFix<16,16> or UFix<24,8> for well defined (and well tested) behaviors.

Note
This should work OK with tables 2048 cells or smaller and frequencies up to 4096 Hz. Can't be used with UPDATE_RATE less than 64 Hz.
-
-This didn't run faster than float last time it was tested, after 2014 code changes. Need to see if 2014 changes improved or worsened performance.

-
- -

Set the frequency using UFix<24,8> fixed-point number format.

-

This might be faster than the float version for setting low frequencies such as 1.5 Hz, or other values which may not work well with your table size. A UFix<24,8> representation of 1.5 is 384 (ie. 1.5 * 256). Can't be used with UPDATE_RATE less than 64 Hz.

Detailed Description

-

PDResonant is a simple midi instrument using Phase distortion used to simulate resonant filter, based on https://en.wikipedia.org/wiki/Phase_distortion_synthesis.

-

The class shows how the Mozzi Phasor class can be used to generate an index into a wavetable, and an ADSR is used to modulate the effect by modifying the Phasor frequency and sync. More complex phase distortion effects could be developed by using precalculated tables, or calcuating tables on the fly using a double buffer, or a line-breakpoint model, a sort of hybridPhasor-Line object.

uint32_t Phasor< UPDATE_RATE >::phaseIncFromFreq (int frequency)
- 		-inline
-
- -

phaseIncFromFreq() and setPhaseInc() are for saving processor time when sliding between frequencies.

-

Instead of recalculating the phase increment for each frequency in between, you can just calculate the phase increment for each end frequency with phaseIncFromFreq(), then use a Line to interpolate on the fly and use setPhaseInc() to set the phase increment at each step. (Note: I should really profile this with the oscilloscope to see if it's worth the extra confusion!)

Parameters
- - -
frequencyfor which you want to calculate a phase increment value.
-
-
-
Returns
the phase increment value which will produce a given frequency.

#include <ReverbTank.h>

Detailed Description

-

A reverb which sounds like the inside of a tin can.

-

ReverbTank is small enough to fit on the Arduino Nano, which for some reason wasn't able to fit a larger version which did fit on other 328 based boards. For simplicity, ReverbTank has hardcoded maximum delay sizes but also has default delay times which can be changed in the constructor or by setting during run time to allow live tweaking. This is a highly simplified design drawing on and probably misinterpreting Miller Puckette's G08.reverb recirculating reverb example for Pure Data.

-

The room size according to the maximum delay lengths corresponds to:

-

early reflections and recirculating delay 1: 128/16384 seconds * 340.29 m/s speed of sound = 3.5 metres recirculating delay 2: 7 metres It looks bigger on paper than it sounds.

Sample< NUM_TABLE_CELLS, UPDATE_RATE, INTERP > Class Template Reference
-
-
- -

Sample is like Oscil, it plays a wavetable. - More...

- -

#include <Sample.h>

-

Detailed Description

-

template<unsigned int NUM_TABLE_CELLS, unsigned int UPDATE_RATE, uint8_t INTERP = INTERP_NONE>
-class Sample< NUM_TABLE_CELLS, UPDATE_RATE, INTERP >

- -

Sample is like Oscil, it plays a wavetable.

-

However, Sample can be set to play once through only, with variable start and end points, or can loop, also with variable start and end points. It defaults to playing once through the whole sound table, from start to finish.

Template Parameters
- - - -
NUM_TABLE_CELLSThis is defined in the table ".h" file the Sample will be using. The sound table can be arbitrary length for Sample. It's important that NUM_TABLE_CELLS is either a literal number (eg. "8192") or a defined macro, rather than a const or int, for the Sample to run fast enough.
UPDATE_RATEThis will be MOZZI_AUDIO_RATE if the Sample is updated in updateAudio(), or MOZZI_CONTROL_RATE if it's updated each time updateControl() is called. It could also be a fraction of MOZZI_CONTROL_RATE if you are doing some kind of cyclic updating in updateControl(), for example, to spread out the processor load.
-
-
-

-int8_t2mozzi

-

Converting soundfiles for Mozzi. There is a python script called int8_t2mozzi.py in the Mozzi/python folder. The script converts raw sound data saved from a program like Audacity. Instructions are in the int8_t2mozzi.py file.

-
- -

phaseIncFromFreq() and setPhaseInc() are for saving processor time when sliding between frequencies.

-

Instead of recalculating the phase increment for each frequency in between, you can just calculate the phase increment for each end frequency with phaseIncFromFreq(), then use a Line to interpolate on the fly and use setPhaseInc() to set the phase increment at each step. (Note: I should really profile this with the oscilloscope to see if it's worth the extra confusion!)

Parameters

void Sample< NUM_TABLE_CELLS, UPDATE_RATE, INTERP >::setFreq (float frequency)
- 		-inline
-
- -

Set the sample frequency with a float.

-

Using a float is the most reliable way to set frequencies, -Might- be slower than using an int but you need either this or setFreq_Q24n8 for fractional frequencies.

Parameters
- - -
frequencyto play the wave table.

void Sample< NUM_TABLE_CELLS, UPDATE_RATE, INTERP >::setFreq (int frequency)
- 		-inline
-
- -

Set the oscillator frequency with an unsigned int.

-

This is faster than using a float, so it's useful when processor time is tight, but it can be tricky with low and high frequencies, depending on the size of the wavetable being used. If you're not getting the results you expect, try explicitly using a float, or try setFreq_Q24n8.

Parameters
- - -
frequencyto play the wave table.

- - - - - - - - -
void Sample< NUM_TABLE_CELLS, UPDATE_RATE, INTERP >::setFreq_Q24n8 (Q24n8 frequency)
- 		-inline
-
- -

Set the frequency using Q24n8 fixed-point number format.

-

This might be faster than the float version for setting low frequencies such as 1.5 Hz, or other values which may not work well with your table size. Note: use with caution because it's prone to overflow with higher frequencies and larger table sizes. An Q24n8 representation of 1.5 is 384 (ie. 1.5 * 256).

Parameters
- - -
frequencyin Q24n8 fixed-point number format.

A sample player for samples encoded with Huffman compression. - More...

- -

#include <SampleHuffman.h>

-

Detailed Description

-

A sample player for samples encoded with Huffman compression.

-

This class and the audio2huff.py script are adapted from "audioout", an Arduino sketch by Thomas Grill, 2011 http//grrrr.org

-

Huffman decoding is used on sample differentials, saving 50-70% of space for 8 bit data, depending on the sample rate.

-

This implementation just plays back one sample each time next() is called, with no speed or other adjustments. It's slow, so it's likely you will only be able to play one sound at a time.

-

Audio data, Huffman decoder table, sample rate and bit depth are defined in a sounddata.h header file. This file can be generated for a sound file with the accompanying Python script audio2huff.py, in Mozzi/extras/python/

-

Invoke with: python audio2huff.py –sndfile=arduinosnd.wav –hdrfile=sounddata.h –bits=8 –name=soundtablename

-

You can resample and dither your audio file with SOX, e.g. to 8 bits depth @ Mozzi's 16384 Hz sample rate: sox fullglory.wav -b 8 -r 16384 arduinosnd.wav

-

Alternatively you can export a sound from Audacity, which seems to have less noticeable or no dithering, using Project Rate 16384 Hz and these output options: Other uncompressed files, Header: WAV(Microsoft), Encoding: Unsigned 8 bit PCM

-

The header file contains two lengthy arrays: One is "SOUNDDATA" which must fit into Flash RAM (available in total: 32k for ATMega328) The other is "HUFFMAN" which must also fit into Flash RAM

A simple infinite impulse response low pass filter for smoothing control or audio signals. - More...

#include <Smooth.h>

Detailed Description

-

template<class T>
-class Smooth< T >

- -

A simple infinite impulse response low pass filter for smoothing control or audio signals.

-

This algorithm comes from http://en.wikipedia.org/wiki/Low-pass_filter: y[i] := y[i-1] + α * (x[i] - y[i-1]), translated as out = last_out + a * (in - last_out). It's not calibrated to any real-world update rate, so if you use it at MOZZI_CONTROL_RATE and you change MOZZI_CONTROL_RATE, you'll need to adjust the smoothness value to suit.

Template Parameters
- - -
Tthe type of numbers being smoothed. Watch out for numbers overflowing the internal calculations. Some experimentation is recommended.
-
-
-
Note
Timing: ~5us for 16 bit types, ~1us for 8 bit types.

Constructor.

-

This constructor which doesn't take a smoothness parameter is useful when you incorporate Smooth into another class definition. You need to call setSmoothness(float) for your object before using Smooth.

Note
there's probably a better way to do this...

State Variable Filter (approximation of Chamberlin version) Informed by pseudocode at http://www.musicdsp.org/showone.php?id=23 and.

-

http://www.musicdsp.org/showone.php?id=142. Here's the original:

-

cutoff = cutoff freq in Hz fs = sampling frequency //(e.g. 44100Hz) f = 2 sin (pi * cutoff / fs) //[approximately] q = resonance/bandwidth [0 < q <= 1] most res: q=1, less: q=0 low = lowpass output high = highpass output band = bandpass output notch = notch output

-

scale = q

-

low=high=band=0;

-

–beginloop low = low + f * band; high = scale * input - low - q*band; band = f * high + band; notch = high + low;

–endloop

Template Parameters
- - -
FILTER_TYPEchoose between LOWPASS, BANDPASS, HIGHPASS and NOTCH.
-
-
-
Note
To save processing time, this version of the filter does not saturate internally, so any resonant peaks are unceremoniously truncated. It may be worth adding code to constrain the internal variables to enable resonant saturating effects.

Parameters
- - -
resonancea byte value between 1 and 255. The lower this value is, the more resonant the filter. At very low values, the filter can output loud peaks which can exceed Mozzi's output range, so you may need to attenuate the output in your sketch.

template<int8_t ALGORITHM>
-class WavePacket< ALGORITHM >

- -

Wavepacket synthesis, with two overlapping streams of wave packets.

-

Draws on Miller Puckette's Pure Data example, F14.wave.packet.pd. Each packet is an enveloped grain of a sin (or cos) wave. The frequency of the wave, the width of the envelopes and the rate of release of envelopes are the parameters which can be changed.

Template Parameters
- - -
ALGORITHMoptions are SINGLE or DOUBLE, for a single non-overlapping stream of packets or a double, overlapping stream.

-
Parameters
- - -
inthe input signal. For flexibility, it's up to you to give the correct offset to your input signal. So if you're mapping a signed 9-bit signal (such as the sum of 2 8-bit Oscils) into a 512 cell table centred around cell 256, add 256 to offset the input value. With a sigmoid table, this may be useful for compressing a bigger signal into the -244 to 243 output range of Mozzi, rather than dividing the signal and returning a int8_t from updateAudio().
-
-
-
Returns
the shaped signal.

-
15  * @page hardware_avr Mozzi on classic Arduino, Teensy 2.x, Arduino Mega, and other 8 bit "AVR"/ATMEGA architecture boards
-
16  *
-
17  * @section avr_status Port status and notes
-
18  * This is the original "port" of Mozzi, and thus very elaborate. The main challenges on this platform, compared to other MCUs, are limitations in
-
19  * flash, RAM, and CPU power.
-
20  *
-
21  * @section avr_output Output modes
-
22  * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
-
23  * - MOZZI_OUTPUT_PWM
-
24  * - MOZZI_OUTPUT_2PIN_PWM
-
25  * - MOZZI_OUTPUT_EXTERNAL_TIMED
-
26  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
27  *
-
28  * In all modes, except MOZZI_OUTPUT_EXTERNAL_CUSTOM, Timer 1 is claimed, and is not available for any other purpose.
-
29  * This means, among other things, that pins 9 and 10 cannot be used for analogWrite(), while pins 3 and 11 should still be available
-
30  * @em except in MOZZI_OUTPUT_2PIN_PWM mode (as Timer2 is also claimed, then; for definite info on which pin is connected to which timer,
-
31  * check a suitable reference, as your board may differ). See *Mozzi>examples>11.Communication>Sinewave_PWM_pins_HIFI*. for an example
-
32  * of emulating analogWrite() on any digital pin, without the need for a hardware timer.
-
33  *
-
34  * @section avr_pwm MOZZI_OUTPUT_PWM
-
35  * For MOZZI_OUTPUT_PWM, output is restricted to pins that are hardware-attached to Timer 1, but can be configured
-
36  * within this tight limit. In particular, the default setup on the
-
37  * Arduino UNO is:
-
38  * - Mono: Pin 9 -> configurable using MOZZI_AUDIO_PIN_1
-
39  * - Stereo: Pin 9 (left) and Pin 10 (right) -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_2
-
40  * For pinouts on other boards, refer to config/known_16bit_timers.
-
41  *
-
42  * Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE: MOZZI_PWM_RATE.
-
43  *
-
44  * The available sample resolution is 488, i.e. almost 9 bits, providing some headroom above the 8 bit table resolution
-
45  * currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.
-
46  *
-
47  * @section avr_2pin_pwm MOZZI_OUTPUT_2PIN_PWM
-
48  * In this mode, output is split across two pins (again, both connected to Timer 1), with each outputting 7 bits for a total of 14. This allows for
-
49  * much better dynamic range, providing much more definition than can be achieved using @ref avr_pwm , while using
-
50  * only modestly more processing power. Further, it allows for a much higher PWM carrier rate can be much higher (125 kHz by default; see @ref
-
51  * MOZZI_PWM_RATE), which is well beyond the audible range.
-
52  *
-
53  * On the downside, this mode requires an extra hardware timer (Timer2 in addition to Timer1), which may increase compatibility
-
54  * problems with other Arduino libraries that also require a timer. Further, a more elaborate hardware setup is needed, making it less convenient
-
55  * for rapid prototyping. For circuit details, see https://sensorium.github.io/Mozzi/learn/output/ .
-
56  *
-
57  * On the classic Arduino Uno, the default pinout in this mode is:
-
58  * - Pin 9 (high bits) and Pin 10 (low bits) -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_1_LOW
-
59  *
-
60  * Here is table of the default pins on some other boards. Rows with an x on it have actually been tested (and importantly, the outcome recoreded;
-
61  * input welcome on further boards.)

-
80  *
-
81  * The default sample resolution is 7 bits per pin, for a total of 14 bits. This can be configured within hardware limits (@ref MOZZI_PWM_RATE) using
-
82  * @ref MOZZI_AUDIO_BITS_PER_CHANNEL, but beware that increasing this will require even more accuracy in our output resistors (see the linked documentation, above).

-
16  * @page hardware_esp32 Mozzi on ESP32-based boards.
-
17  *
-
18  * port by Dieter Vandoren and Thomas Friedrichsmeier
-
19  *
-
20  * @section esp32_status Port status and notes
-
21  * - Since flash memory is not built into the ESP32, but connected, externally, it is much too slow for keeping wave tables, audio samples, etc. Instead, these are kept in RAM on this platform.
-
22  * - Asynchronous analog reads are not implemented. `mozziAnalogRead()` relays to `analogRead()`. @ref MOZZI_AUDIO_INPUT is not implemented
-
23  * - twi_nonblock is not ported
-
24  * - WIFI-activity not yet tested, but likely the same notes as for ESP8266 apply, i.e. @em any Wifi activity is likely to introdcue considerable nose. Consider turning off WIFI.
-
25  * - The implementation of audioTicks() may be slightly inaccurate on this platform.
-
26  *
-
27  * @section esp32_output Output modes
-
28  * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
-
29  * - MOZZI_OUTPUT_EXTERNAL_TIMED
-
30  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
31  * - MOZZI_OUTPUT_PDM_VIA_I2S
-
32  * - MOZZI_OUTPUT_I2S_DAC
-
33  * - MOZZI_OUTPUT_INTERNAL_DAC
-
34  *
-
35  * The default mode is @ref esp32_internal_dac .
-
36  *
-
37  * @section esp32_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
-
38  * The internal DAC has 8 bit resolution, and outputs to GPIO pins 25 and 26 (non-configurable). For simplicity of code, both pins are always used.
-
39  * In a mono configuration, both pins output the same sample.
-
40  *
-
41  * TODO: We could really use this to hack in a 2 PIN mode!
-
42  *
-
43  * @note
-
44  * The number 25 refers to "GPIO 25" or sometimes labelled "D25". Confusingly, many boards come with an additional, totally different numbering scheme on top of that.
-
45  * Check a detailed pinout diagram, if in any doubt.
-
46  *
-
47  * Internally, the inbuilt DAC is connected via an I2S interface. Which interface number to use can be configured using:
-
48  *
-
49  * @code
-
50  * #define MOZZI_I2S_PORT ... // (default: I2S_NUM_0)
-
51  * @endcode
-
52  *
-
53  * @section esp32_i2s_dac MOZZI_OUTPUT_I2S_DAC
-
54  * This mode outputs to a PT8211 (or compatible) I2S DAC, which allows for very high quality (mono or stereo) output. Communication needs the BCK, WS, and DATA(out) pins
-
55  * of one I2S interface. Presumably, any pins qualify, and you can configure this using:
-
56  * @code
-
57  * #define MOZZI_I2S_PIN_BCK ... // (default: 26)
-
58  * #define MOZZI_I2S_PIN_WS ... // (default: 15)
-
59  * #define MOZZI_I2S_PIN_DATA ... // (default: 33)
-
60  * #define MOZZI_I2S_PORT ... // (default: I2S_NUM_0)
-
61  * @endcode
-
62  *
-
63  * See the note above (@ref esp_internal_dac) regarding pin numbering. Also, please always test the default pinout, should a custom setting fail!
-
64  *
-
65  * As a technical note, I2S support in the ESP32 SDK has been reworked since this was implemented in Mozzi, and Mozzi uses the "legacy" implementation "i2s.h".
-
66  * This should not be an issue, unless you want to connect additional I2S components, yourself. In which case contributions are certainly welcome!
-
67  *
-
68  * @section esp32_pdm_via_i2s MOZZI_OUTPUT_PDM_VIA_I2S
-
69  * This mode uses the same setup as @ref esp32_i2s_dac, but rather than using an external DAC, the communication signal itself is modulated in PDM
-
70  * (pulse density modulation) encoded form. Thus not extra hardware is needed, and the signal is output on the DATA pin (see above). The BCK and
-
71  * WS pins are also claimed, but should be left non-connected, and do not produce anything meaningful. This can only be used in mono mode.
-
72  *
-
73  * Output resolution may be adjusted by defining MOZZI_PDM_RESOLUTION , where the default value of 4 means that each audio sample is encoded into four 32 bit blocks
-
74  * of ones and zeros. Obviously, more is potentially better, but at the cost of considerable computation power.
-
75  *
-
76  * @section esp32_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
77  * See @ref external_audio

18  * port by Thomas Friedrichsmeier
-
19  *
-
20  * @section esp8266_status Port status and notes
-
21  * - Since flash memory is not built into the ESP8266, but connected, externally, it is much too slow for keeping wave tables, audio samples, etc. Instead, these are kept in RAM on this platform.
-
22  * - Asynchronous analog reads are not implemented. `mozziAnalogRead()` relays to `analogRead()`. @ref MOZZI_AUDIO_INPUT is not available
-
23  * - twi_nonblock is not ported
-
24  * - Note that the ESP8266 pins can output less current than the other supported CPUs. The maximum is 12mA, with a recommendation to stay below 6mA.
-
25  * - WHEN CONNECTING A HEADPHONE, DIRECTLY, USE APPROPRIATE CURRENT LIMITING RESISTORS (>= 500Ohms).
-
26  * - _Any_ WiFi-activity can cause severe spikes in power consumption. This can cause audible "ticking" artifacts, long before any other symptoms.
-
27  * - If you do not require WiFi in your sketch, you should turn it off, _explicitly_, using @code WiFi.mode(WIFI_OFF) @endcode.
-
28  * - A juicy enough, well regulated power supply, and a stabilizing capacitor between VCC and Gnd can help a lot.
-
29  * - As the (PDM) output signal is digital, a single (fast!) transistor can be used to amplify it to an independent voltage level.
-
30  * - audioHook() calls `yield()` once for every audio sample generated. Thus, as long as your audio output buffer does not run empty, you should not need any additional `yield()`s inside `loop()`.
-
31  *
-
32  * @section esp8266_output Output modes
-
33  * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
-
34  * - MOZZI_OUTPUT_EXTERNAL_TIMED
-
35  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
36  * - MOZZI_OUTPUT_PDM_VIA_I2S
-
37  * - MOZZI_OUTPUT_PDM_VIA_SERIAL
-
38  * - MOZZI_OUTPUT_I2S_DAC
-
39  *
-
40  * The default mode is @ref esp8266_pdm_via_serial .
-
41  *
-
42  * @note
-
43  * This port really does not currently come with a PWM mode!
-
44  *
-
45  * @section esp8266_pdm_via_serial MOZZI_OUTPUT_PDM_VIA_SERIAL
-
46  * Output is coded using pulse density modulation, and sent via GPIO2 (Serial1 TX).
-
47  * - This output mode uses timer1 for queuing audio sample, so that timer is not available for other uses.
-
48  * - Note that this mode has slightly lower effective analog output range than @ref esp8266_pdm_via_i2s, due to start/stop bits being added to the output stream.
-
49  * - Supports mono output, only, pins not configurable.
-
50  *
-
51  * The option @ref MOZZI_PDM_RESOLTUON (default value 2, corresponding to 64 ones and zeros per audio sample) can be used to adjust the output resolution.
-
52  * Obviously higher values demand more computation power.
-
53  *
-
54  * @section esp8266_pdm_via_serial MOZZI_OUTPUT_PDM_VIA_I2S
-
55  * Output is coded using pulse density modulation, and sent via the I2S pins. The I2S data out pin (GPIO3, which is also "RX") will have the output,
-
56  * but *all* I2S output pins (RX, GPIO2 and GPIO15) will be affected. Mozzi tries to set GPIO2 and GPIO15 to input mode, and *at the time of this writing*, this allows
-
57  * I2S output on RX even on boards such as the ESP01 (where GPIO15 is tied to Ground). However, it seems safest to assume that this mode may not be useable on boards where
-
58  * GPIO2 or GPIO15 are not available as output pins.
-
59  *
-
60  * Supports mono output, only, pins not configurable.
-
61  *
-
62  * Resolution may be controlled using MOZZI_PDM_RESOLUTION (see above; default value is 2).
-
63  *
-
64  * @section esp8266_i2s_dac MOZZI_OUTPUT_I2S_DAC
-
65  * Output is sent to an external DAC (such as a PT8211), digitally coded. This is the only mode that supports stereo (@ref MOZZI_AUDIO_CHANNELS). It also needs the least processing power.
-
66  * The pins cannot be configured (GPIO3/RX, GPIO2, and GPIO15).

-
16  * @page hardware_mbed Mozzi on MBED-based boards (Arduino Giga / Portenta).
-
17  *
-
18  * port by Thomas Friedrichsmeier & Thomas Combriat
-
19  *
-
20  * @section mbed_status Port status and notes
-
21  * Compiles and runs using Arduino's standard and Arduino_AdvancedAnalog libraries. This port is still **experimental**, testing reveals
-
22  * some instabilities for some configurations (in particular with @ref MOZZI_AUDIO_INPUT) that are under active investigations.
-
23  *
-
24  * This port is not complete yet, in particular:
-
25  * - Asynchroneous analog reads are not implemented (yet), `mozziAnalogRead()` relays to `analogRead()`. (Note that @ref MOZZI_AUDIO_INPUT @em is implemented!)
-
26  * - This port should support other MBED based Arduino boards like the Arduino Portenta, in *theory*, but the developer have only tested it on the Giga. Feedback welcome!
-
27  *
-
28  * @section mbed_output Output modes
-
29  * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
-
30  * - MOZZI_OUTPUT_EXTERNAL_TIMED
-
31  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
32  * - MOZZI_OUTPUT_PDM_VIA_SERIAL
-
33  * - MOZZI_OUTPUT_INTERNAL_DAC
-
34  *
-
35  * The default mode is @ref mbed_internal_dac .
-
36  *
-
37  * @section mbed_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
-
38  * This uses the inbuild DAC on the board. The default is setting is appropriate for the Arduino Giga: 12 bits going to A13 (3.5mm jack connector's tip),
-
39  * and in stereo mode to pin A12 (3.5mm jack connector's first ring) additionally.
-
40  *
-
41  * For other boards is may be appropriate to customize:
-
42  * @code
-
43  * #define MOZZI_AUDIO_PIN_1 ... // mono / left channel; default: A13
-
44  * #define MOZZI_AUDIO_PIN_2 ... // stereo only: right channel; default: A12
-
45  * #define MOZZI_AUDIO_BITS ... // default is 12
-
46  * @endcode
-
47  *
-
48  * @section mbed_pdm_via_serial MOZZI_PDM_VIA_SERIAL
-
49  * Returns a pulse-density modulated (mono only) signal on one of the hardware UARTs of the board (Serial ports). Default is using the SERIAL2, on pin D18.
-
50  * You can confiugre the pins to use, but it must be connected to a hardware UART. Output is written to the TX pin, only, but the RX pin needs to be
-
51  * claimed as well. Beware of confusing pinout labelling, for instance SERIAL2_TX iss labelled "TX1" on the Arduino Giga. The audio resolution can be enhanced
-
52  * using @ref MOZZI_PDM_RESOLUTION, which is described in more detail here: @esp32_pdm_via_i2s .
-
53  *
-
54  * Configuration options:
-
55  * @code
-
56  * #define MOZZI_SERIAL_PIN_TX ... // default: SERIAL2_TX
-
57  * #define MOZZI_SERIAL_PIN_RX ... // *must* specify the matching one, if customizing the above; default: SERIAL2_RX
-
58  * #define MOZZI_PDM_RESOLUTION ... // default value is 2, for 2*32 ones and zeros per audio sample
-
59  * @endcode
-
60  *
-
61  * @section mbed_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM

-
22  *
-
23  * A few particularities:
-
24  * - Because this board has an on-board DAC (A0), but only one, STEREO is not implemented and Mozzi uses this pin. Usage of other pins using PWM for instance is not implemented yet.
-
25  * - getAudioInput() and mozziAnalogRead() return values in the Renesas' full ADC resolution of 0-16384 rather than AVR's 0-1023. *This might change in the near future for speed purposes.*

-
34  *
-
35  * @section renesas_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
-
36  * This uses the inbuild DAC on the board on pin A0. Mono output only, and the pin is not configurable. Audio resolution is also fixed at 12 bits (which is what the board supports).
-
37  *
-
38  * This mode claims two timers (but it is not hardcoded, which ones).
-
39  *
-
40  * @section renesas_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM

16  * @page hardware_rp2040 Mozzi on RP2040 (Raspberry Pi Pico)
-
17  *
-
18  * port by Thomas Friedrichsmeier
-
19  *
-
20  * @section rp2040_status Port status and notes
-
21  * Compiles and runs using [this core](https://github.com/earlephilhower/arduino-pico). Can probably be ported to the Mbed core for RP2040, relatively easily,
-
22  * as it relies mostly on the RP2040 SDK API. Tested on a Pi Pico.
-
23  *
-
24  * - This is a recent addition, implementation details may still change (currently just PWM driven by a timer; this may be worth changing to a DMA driven output)
-
25  * - Wavetables and samples are not kept in progmem on this platform. While apparently speed (of the external flash) is not much of an issue, the data always seems to be copied into RAM, anyway.
-
26  * - Note that getAudioInput() and mozziAnalogRead() return values in the RP2040's full ADC resolution of 0-4095 rather than AVR's 0-1023.
-
27  * - twi_nonblock is not ported
-
28  * - Code uses only one CPU core
-
29  *
-
30  * @section rp2040_output Output modes
-
31  * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
-
32  * - MOZZI_OUTPUT_EXTERNAL_TIMED
-
33  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
34  * - MOZZI_OUTPUT_PWM
-
35  * - MOZZI_OUTPUT_I2S_DAC
-
36  *
-
37  * The default mode is @ref rp2040_pwm .
-
38  *
-
39  * @section rp2040_pwm MOZZI_OUTPUT_PWM
-
40  * Audio output is written to pin 0 (mono) or 0 and 1 (stereo), by default, with 11 bits of ouput resolution.
-
41  * One hardware timer interrupt and one DMA channel are claimed (number not hardcoded), a non-exclusive handler is installed on DMA_IRQ_0.
-
42  *
-
43  * Configuration options:
-
44  * @code
-
45  * #define MOZZI_AUDIO_PIN_1 ... // default is 0
-
46  * #define MOZZI_AUDIO_BITS ... // output resolution (bits); default is 11
-
47  * // additionally, for stereo:
-
48  * #define MOZZI_AUDIO_PIN_2 ... // default is 1; this must be on the same PWM slice as the first pin (i.e. neighboring)
-
49  * @endcode
-
50  *
-
51  * @section rp2040_i2s_dac MOZZI_OUTPUT_I2S_DAC
-
52  * Output to an external DAC, connected via I2S. This uses 16 bit (per audio channel), but can be changed to 8, 16, 24 (left aligned) and 32 resolution.
-
53  * Both plain I2S and LSBJ format (PT8211 needs this, for instance) are available. Plain format is used by default. The GPIO pins to use can be configured,
-
54  * - almost - freely (see below). Two DMA channels are claimed (numbers not hardcoded), non-exclusive handlers are installed on DMA_IRQ_0.
-
55  *
-
56  * Configuration options:
-
57  * @code
-
58  * #define MOZZI_AUDIO_BITS ... // available values are 8, 16 (default), 24 (LEFT ALIGN in 32 bits type!!) and 32 bits
-
59  * #define MOZZI_I2S_PIN_BCK ... // /BLCK) default is 20
-
60  * //#define MOZZI_I2S_PIN_WS (MOZZI_I2S_PIN_BCK+1) ... // CANNOT BE CHANGED, HAS TO BE NEXT TO pBCLK, i.e. default is 21
-
61  * #define MOZZI_I2S_PIN_DATA ... // (DOUT) default is 22
-
62  * #define MOZZI_I2S_FORMAT ... // may be MOZZI_I2S_FORMAT_LSBJ or MOZZI_I2S_FORMAT_PLAIN (default)
-
63  * @endcode
-
64  *
-
65  * @note
-
66  * The MOZZI_I2S_FORMAT_LSBJ option may require a relatively recent git-hub checkout of the arduino-pico core.

-
16 * @page hardware_stm32_disambiguation Mozzi on STM32-based boards - disambiguation
-
17 *
-
18 * * The situation on STM32-based boards is rather confusing, as there are several competing Arduino cores. Importantly:
-
19 * - Some boards use dedicated cores (e.g. Arduino Giga / Portenta @ref hardware_mbed) etc. For those, see the relevant sections (if we support them).
-
20 * - There is a series of libmaple-based cores, including [Roger Clark's libmaple-based core](https://github.com/rogerclarkmelbourne/Arduino_STM32). These are highly optimized,
-
21 * and provide very complete support, but only for a limited number of boards. Unfortunately, at the time of this writing (2023/04), they are not available for installation
-
22 * via the Arduino Board Manager, and they do not currently seem actively maintained.
-
23 * For using these with Mozzi, see @ref hardware_stm32_maple
-
24 * - A generic Arduino core for STM32 is the [STM32duino core](https://github.com/stm32duino/Arduino_Core_STM32). It supports a huge set of boards, and seems to have offical
-
25 * backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what
-
26 * the libmaple cores above were known by (don't blame Mozzi for this mess!).
-
27 * For using this with Mozzi, see @ref hardware_stm32duino

-
34  *
-
35  * @note
-
36  * Be sure to understand the info given at @ref hardware_stm32_disambiguation . This page is about using Mozzi with the STM32duino core.
-
37  *
-
38  * @section stm32duino_status Port status and usage notes
-
39  * Tested on a STM32F103C8T6 blue pill board as well as an STM32F411CE black pill board, i.e. on sboards _without_ a
-
40  * real DAC. Compiles and runs, with a bunch of caveats (see below). Should probably run on any other board supported by the
-
41  * [STM32duino core](https://github.com/stm32duino/Arduino_Core_STM32) (although this theory is untested).
-
42  * When trying any other board, you probably want to check the platform specific settings (see below), carefully, importantly, whether the desired output resolution is
-
43  * achievable, and whether the desired output pins are PWM capable.
-
44  *
-
45  * - @ref MOZZI_ANALOG_READ input implementation is somewhat experimental, and may not be able to service a whole lot of pins (contributions welcome)
-
46  * - @ref MOZZI_AUDIO_INPUT is completely untested (but implemented in theory; feedback welcome!)
-
47  * - getAudioInput() and mozziAnalogRead() return values in the STM32's full ADC resolution (the exact range depending on the board in use) rather than AVR's 0-1023.
-
48  * - twi_nonblock is not ported
-
49  *
-
50  * @section stm32duino_output_modes Output modes
-
51  * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
-
52  * - MOZZI_OUTPUT_EXTERNAL_TIMED
-
53  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
54  * - MOZZI_OUTPUT_PWM
-
55  * - MOZZI_OUTPUT_PWM_2PIN
-
56  *
-
57  * The default mode is @ref stm32duino_pwm .
-
58  *
-
59  * @note
-
60  * This port may look similar to, but uses a different default GPIO pinout than @hardware_stm32_maple !
-
61  *
-
62  * @section stm32duino_pwm MOZZI_OUTPUT_PWM
-
63  * Standard pulse width modulated output to one (mono) or two (stereo, see @ref MOZZI_AUDIO_CHANNELS) GPIO pins. Default pinout: PA8 (mono/left), PA9 (right channel in stereo).
-
64  * This mode uses two hardware timers: One for the PWM (Timer 3 when using the default pin configuration), and a second for updating the output at audio rate.
-
65  * The default audio resolution is 10 bits, which results in a carrier frequency of ~70kHz on a 72MHz CPU. On slower boards you will have to descrease this.
-
66  * The following settings may be costumized, if desired:
-
67  *
-
68  * @code
-
69  * #define MOZZI_AUDIO_PIN_1 ... // Left / mono output pin. Default: PA8
-
70  * #define MOZZI_AUDIO_UPDATE_TIMER ... // Second hardware timer to claim, must not be the same of the timer for the above pin. Default TIM2
-
71  * #define MOZZI_AUDIO_BITS ... // Output resolution in bits. Default is 10
-
72  * // For stereo, only:
-
73  * #define MOZZI_AUDIO_PIN_2 ... // Right channel output pin. This *must* be connected to the same hardware timer as MOZZI_AUDIO_PIN_1 ! Default: PA9
-
74  * @endcode
-
75  *
-
76  * @section stm32duino_pwm MOZZI_OUTPUT_2PIN_PWM
-
77  * This mode is very similar to @ref stm32duino_pwm, but splitting output for a single channel across two GPIO pins for better resolution. For details on the required
-
78  * hardware setup, and configuration tradeoffs, see @ref avr_2pin_pwm . Stereo output is not available in this mode.
-
79  * Output is at 2*7 bits at up to 560kHz carrier frequency (but limited to 5 times audio rate).
-
80  *
-
81  * Customizable configuration options:
-
82  * @code
-
83  * #define MOZZI_AUDIO_PIN_1 ... // High byte of the output. Default: PA8
-
84  * #define MOZZI_AUDIO_PIN_1_LOW ... // Low byte of the output. Default: PA9
-
85  * #define MOZZI_AUDIO_UPDATE_TIMER ... // Second hardware timer to claim. Default TIM2
-
86  * #define MOZZI_AUDIO_BITS_PER_CHANNEL ... // Bits per pin. Default is 7
-
87  * @endcode
-
88  *
-
89  * @section stm32duino_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
90  * See @ref external_audio .
-
91  * The (single) hardware timer claimed for MOZZI_OUTPUT_EXTERNAL_TIMED may be configured using "MOZZI_AUDIO_UPDATE_TIMER" (default: TIM2).

-
18  *
-
19  * @note
-
20  * Be sure to understand the info given at @ref hardware_stm32_disambiguation . This page is about using Mozzi with the STM32 "libmaple based" core.
-
21  *
-
22  * @note
-
23  * This port may look similar to, but uses a different default GPIO pinout than @ref @hardware_stm32duino !
-
24  *
-
25  * @section stm32_maple_status Status and peculiarities of this port
-
26  * Compiles for and runs on a STM32F103C8T6 blue pill board, with a bunch of caveats (see below), i.e. on a board _without_ a
-
27  * real DAC. Should probably run on any other board supported by [Roger Clark's libmaple-based core](https://github.com/rogerclarkmelbourne/Ardu0ino_STM32) (although this theory is untested).
-
28  *
-
29  * @note that at the time of this writing, [Stev Strong's slightliy more recent fork of this core](https://github.com/stevstrong/Arduino_STM32/) does *not* work with
-
30  * Mozzi, apparently due to a bug in pwmWrite().
-
31  *
-
32  * - If you want to use MIDI, be sure to replace "MIDI_CREATE_DEFAULT_INSTANCE()" with "MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI)" (or Serial2)
-
33  * - @ref MOZZI_AUDIO_INPUT_STANDARD is implemented in theory, but untested (feedback welcome)
-
34  * - getAudioInput() and mozziAnalogRead() return values in the STM32's full ADC resolution of 0-4095 rather than AVR's 0-1023.

-
37  * @section stm32_output_modes Output modes
-
38  *
-
39  * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
-
40  * - MOZZI_OUTPUT_EXTERNAL_TIMED
-
41  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
42  * - MOZZI_OUTPUT_PWM
-
43  * - MOZZI_OUTPUT_PWM_2PIN
-
44  *
-
45  * The default mode is @ref stm32_maple_pwm .
-
46  *
-
47  * @section stm32_maple_pwm MOZZI_OUTPUT_PWM
-
48  * Standard pulse width modulated output to one (mono) or two (stereo, see @ref MOZZI_AUDIO_CHANNELS) GPIO pins. Default pinout: PB8 (mono/left), PB9 (right channel in stereo).
-
49  * This mode uses two hardware timers: One for the PWM (Timer 4 when using the default pin configuration), and a second for updating the output at audio rate.
-
50  * The default audio resolution is 10 bits, which results in a carrier frequency of ~70kHz on a 72MHz CPU. On slower boards you will have to descrease this.
-
51  * The following settings may be costumized, if desired:
-
52  *
-
53  * @code
-
54  * #define MOZZI_AUDIO_PIN_1 ... // Left / mono output pin. Default: PB8
-
55  * #define MOZZI_AUDIO_PWM_TIMER ... // Must be set ot the hardware timer connected to the above pin. Default: 4
-
56  * #define MOZZI_AUDIO_UPDATE_TIMER ... // Second hardware timer to claim. Default 2
-
57  * #define MOZZI_AUDIO_BITS ... // Output resolution in bits. Default is 10
-
58  * // For stereo, only:
-
59  * #define MOZZI_AUDIO_PIN_2 ... // Right channel output pin. This *must* be connected to the same hardware timer as MOZZI_AUDIO_PIN_1 ! Default: PB9
-
60  * @endcode
-
61  *
-
62  * @section stm32_maple_2pin_pwm MOZZI_OUTPUT_2PIN_PWM
-
63  * This mode is very similar to @ref stm32_maple_pwm, but splitting output for a single channel across two GPIO pins for better resolution. For details on the required
-
64  * hardware setup, and configuration tradeoffs, see @ref avr_2pin_pwm . Stereo output is not available in this mode.
-
65  * Output is at 2*7 bits at up to 560kHz carrier frequency (but limited to 5 times audio rate).
-
66  *
-
67  * Customizable configuration options:
-
68  * @code
-
69  * #define MOZZI_AUDIO_PIN_1 ... // High byte of the output. Default: PB8
-
70  * #define MOZZI_AUDIO_PIN_2 ... // Low byte of the output. Default: PB9
-
71  * #define MOZZI_AUDIO_PWM_TIMER ... // Must be set to the number of the hardware timer connect to the above pins. Default: 4
-
72  * #define MOZZI_AUDIO_UPDATE_TIMER ... // Second hardware timer to claim. Default TIM2
-
73  * #define MOZZI_AUDIO_BITS_PER_CHANNEL ... // Bits per pin. Default is 7
-
74  * @endcode
-
75  *
-
76  * @section stm32_maple_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
77  * See @ref external_audio
-
78  * The (single) hardware timer claimed for MOZZI_OUTPUT_EXTERNAL_TIMED may be configured using "MOZZI_AUDIO_UPDATE_TIMER" (default: TIM2).

98  * This port has been tested on BOARD A, BOARD B, but is expected to work on other boards using this family of MCUs, too.
-
99  * The default MOZZI_AUDIO_RATE is set to 32678 Hz. Asynchronous analog reads are not yet implemented, so be careful

100  * not to use mozziAnalogRead() too much. Also @ref MOZZI_AUDIO_INPUT is not available.
-
101  *
-
102  * When connecting external circuitry, keep in mind that the GPIO pins on this CPU are rated at a max of 3 mA. Be careful
-
103  * not to over-stress them. It is further recommended not to make use of feature X when using Mozzi, as it will

-
111  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM
-
112  * - MOZZI_OUTPUT_INTERNAL_DAC
-
113  *
-
114  * The default mode is @ref MYPORT_internal_dac , meaning, only boards with an inbuilt DAC are covered by default
-
115  * (you could stil use one of the external output modes, however).
-
116  *
-
117  * @section MYPORT_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
-
118  * Output resolution is 10 bits by default, and goes to pin DAC0. Hardware timer 1 is claimed by Mozzi.

-
120  *
-
121  * @code
-
122  * #define MOZZI_AUDIO_PIN_1 ... // default is DAC0
-
123  * #define MOZZI_AUDIO_BITS ... // default is 10

◆ adcDisconnectAllDigitalIns()

- -
-
- - - - - -
- - - - - - - -
void adcDisconnectAllDigitalIns ()
- 		-inline
-
- -

Prepare all analog input channels by turning off their digital input buffers.

-

This helps to reduce noise, increase analog reading speed, and save power.

- -

Definition at line 111 of file mozzi_analog.h.

- -
-
- -

◆ disconnectDigitalIn()

- -
-
- - - - - -
- - - - - - - - -
void disconnectDigitalIn (uint8_t channel_num)
- 		-inline
-
- -

Prepare an analog input channel by turning off its digital input buffer.

-

This helps to reduce noise, increase analog reading speed, and save power.

-

Here's more detail from http://www.openmusiclabs.com/learning/digital/atmega-adc/:

-

The DIDR (Data Input Disable Register) disconnects the digital inputs from whichever ADC channels you are using. This is important for 2 reasons. First off, an analog input will be floating all over the place, and causing the digital input to constantly toggle high and low. This creates excessive noise near the ADC, and burns extra power. Secondly, the digital input and associated DIDR switch have a capacitance associated with them which will slow down your input signal if you are sampling a highly resistive load.

-

And from the ATmega328p datasheet, p266:

-

When an analog signal is applied to the ADC pin and the digital input from this pin is not needed, this bit should be written logic one to reduce power consumption in the digital input buffer. Note that ADC named_pins ADC7 and ADC6 do not have digital input buffers, and therefore do not require Digital Input Disable bits.

Parameters
- - -
channel_numthe analog input channel you wish to use.
-
-
- -

Definition at line 86 of file mozzi_analog.h.

- -

◆ getAudioInput()

- -
-
-
-template<byte RES>
- - - - - - - -
uint16_t getAudioInput ()
-
- -

See getAudioInput().

-

This returns audio input from the input buffer, if @ref MOZZI_AUDIO_INPUT is enabled in the config (see also the related option MOZZI_AUDIO_INPUT_PIN).

-

The template parameter specifies the desired value range in bits.

-

The audio signal needs to be in the range 0 to VCC volts (i.e. 5 volts on Arduino Uno R3). Circuits and discussions about biasing a signal in the middle of this range can be found at http://electronics.stackexchange.com/questions/14404/dc-biasing-audio-signal and http://interface.khm.de/index.php/lab/experiments/arduino-realtime-audio-processing/ . A circuit and instructions for amplifying and biasing a microphone signal can be found at http://www.instructables.com/id/Arduino-Audio-Input/?ALLSTEPS

-
Note
The value range returned by this function follows the same rules as detailed in the documentation for mozziAnalogRead(): For portable code, define MOZZI_ANALGO_READ_RESOLUTION at the top of your sketch, or use the templated version of this function.
-
Returns
audio data from the input buffer
- -

Definition at line 172 of file MozziGuts.h.

◆ getAudioInput16()

- -
-
-
-template<byte RES>
- - - - - -
- - - - - - - -
uint16_t getAudioInput16 ()
- 		-inline
-
- -

See getAudioInput().

-

Equivalent to getAudioInput<16>().

- -

Definition at line 149 of file MozziGuts.h.

- -
-
- -

◆ mozziAnalogRead()

- -
-
-
-template<byte RES>
- - - - - - - - -
uint16_t mozziAnalogRead (uint8_t pin)
-
- -

See mozziAnalogRead().

-

Reads the analog input of a chosen channel, without blocking other operations from running.

-

The template parameter RES specifies the number of bits to return.

-

It actually returns the most recent analog reading and puts the chosen pin or channel on the stack of channels to be read in the background before the next control interrupt.

-
Note
Analog reads have different hardware resolution on different platforms. E.g. an analog read on an Arduino Uno R3 will return a value in the range 0-1023 (10 bits), on a Raspberry Pi Pico it will return 0-4095 (12 bits). For portable code, it is thus necessary to specify the desired resolution of reads. This can be done by setting MOZZI_ANALOG_READ_RESOLUTION to the resolution in bits, near the top of your sketch. All reads will then be adjusted to that range, automatically (using a simple bit-shift). Alternatively, the templated version of mozziAanalogRead() allows to specifiy the target resolution per read. If MOZZI_ANALOG_READ_RESOLUTION is not defined, this (non-templated) function returns a value in the default hardware resolution, with a warning.
-
Parameters
- - -
pin_or_channelthe analog pin or channel number.
-
-
-
Returns
the digitised value of the voltage on the chosen channel. See the note above regarding the output range!
- -

Definition at line 174 of file mozzi_analog.h.

- -
-
- -

◆ mozziAnalogRead16()

- -
-
- - - - - -
- - - - - - - - -
uint16_t mozziAnalogRead16 (uint8_t pin)
- 		-inline
-
- -

See mozziAnalogRead() but always returns the value shifted to 16 bit range.

-

THis is exactly equivalent to mozziAnalogRead<16>(pin);

- -

Definition at line 152 of file mozzi_analog.h.

- -
-
- -

◆ reconnectDigitalIn()

- -
-
- - - - - -
- - - - - - - - -
void reconnectDigitalIn (uint8_t channel_num)
- 		-inline
-
- -

Reconnect the digital input buffer for an analog input channel which has been set for analog input with disconnectDigitalIn().

-
Parameters
- - -
channel_numthe analog input channel you wish to reconnect.
-
-
- -

Definition at line 99 of file mozzi_analog.h.

- -
-
- -

◆ setupFastAnalogRead()

- -
-
- - - - - - - - -
void setupFastAnalogRead (int8_t speed = FAST_ADC)
-
- -

This is automatically called in startMozzi.

-

It makes mozziAnalogRead() happen faster than the standard Arduino analogRead(), changing the duration from about 105 in unmodified Arduino to about 16 microseconds for a dependable read with the default speed parameter FAST_ADC. If you want to set on of the faster modes (see params) you can call this after startMozzi(). See: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1208715493/11, and http://www.marulaberry.co.za/index.php/tutorials/code/arduino-adc/

Parameters
- - -
speedFAST_ADC, FASTER_ADC or FASTEST_ADC. If no parameter is supplied, the default is FAST_ADC, which sets the analog conversion clock predivide rate to 16, giving 1Mhz on a 16MHz board, the fastest rate for which behaviour is defined (~16us per sample). However, divisors of 8 and 4 also show usable results in the graphs in this paper: http://dam.mellis.org/Mellis%20-%20Sensor%20Library%20for%20Arduino%20-%20Paper.pdf, so you can also try FASTER_ADC or FASTEST_ADC for divide rates of 8 or 4, giving times of about 8us or 4us per sample. Beware, reliable results will depend on the sort of input signal you have. Only use FASTER_ADC or FASTEST_ADC if you know what you're doing.

Basic architecture of audio generation, buffering, and output in Mozzi

Mozzi provides support for audio ouput on a range of different boards and CPUs.This page is about the following related topics:
    -
  • adding a custom output method (importantly using external DACs) to your sketch
    • -
  • writing sketches that will work on different platforms / with different output methods
    • -
  • extending Mozzi for a new architecture
    • -
-For all of these topics, it is helpful to have a basic understanding of the basic output steps in Mozzi:
    -
  1. Inside the loop() function in your sketch you call audioHook(). 1a. If the audio output buffer is currently filled, this does nothing. 1b. Otherwise, this calls updateAudio(). The generated sample is then added to the audio output buffer. (Also, updateControl() will be called at an appropriate rate, and a few other details that are not important for this discussion.)
    2. -
  2. A platform-specific timer is triggered at audio rate (usually), takes a sample from the output buffer and sends it to audioOutput().
    3. -
  3. The audioOutput() function - usually predefined inside Mozzi - takes care of sending the sample to the hardware.
    4. -
-These output steps are not always followed, however. Firstly, when using External audio output output, the audioOutput() funtion is supplied by the user sketch, instead of Mozzi. External audio output output.Some ports will also want to bypass the Mozzi audio output buffer. For instance, an internal DAC may be addressable via an efficient DMA-connected buffer, already, and also have a built-in rate control. In this case, ports will internally set the define BYPASS_MOZZI_OUTPUT_BUFFER to true. Such a port will have to provide a custom definition of canBufferAudioOutput(), returning true, whenever a new sample of output can be accepted. No timer at audio-rate is set up in this case.Finally, the External audio output output mode (MOZZI_AUDIO_MODE MOZZI_OUTPUT_EXTERNAL_CUSTOM) is essentially a combination of the two. Here, the user sketch needs to provide both audioOutput() and canBufferAudioOutput(). The latter is again called from audioHook(), and whenever it returns true, a new sample is generated and passed to audioOutput().

-Platform specific audio resolution

-

Different output methods often support a different resolution of output samples. To provide best performance on slow boards, Mozzi expects your updateAudio() function to return samples in exactly the width that is needed at the output stage. Thus, defining this naively, an updateAudio() function designed for 8 bit output will produce very low volume output on a 16 bit DAC, while the other way around overflows will result in way too loud and heavily distored output. Fortunately, all that is needed to write portable sketches is to specify how many bits your updateAudio() function provides. The (inline) functions in the AudioOutput namespace do just that. Using them makes sure your audio output is shifted if, and as much as needed on all platforms.

External audio output

Only for MOZZI_AUDIO_MODE set to MOZZI_OUTPUT_EXTERNAL_TIMED or MOZZI_OUTPUT_EXTERNAL_CUSTOM. Most (all?) platforms support output using an "external" function. When using this option, you will need to provide a suitable definition for audioOutput() in your own sketch, yourself. Some understanding of the general Mozzi audio output architecture may be recommendable, when using this mode: See AudioOutput .In the more simple case (MOZZI_OUTPUT_EXTERNAL_TIMED), Mozzi will still take care of buffering the samples, and calling this function at audio rate (hence "timed"). This generally involves use of a timer, which should be detailed in the Hardware and configuration details for your platform.Should you desire even more control - perhaps because your board, or your external DAC already comes with a rate controlled DMA buffer - using MOZZI_OUTPUT_EXTERNAL_CUSTOM also bypasses Mozzis sample buffer. In addition to audioOutput(), you will then need to provide a definition for canBufferAudioOutput(), which will control the rate at which samples are produced. In essence, whenever canBufferAudioOutput() returns true, Mozzi will call updateAudio(), and pass the produced sample to audioOutput(), unbuffered. It is entirely your job to make sure that this actually happens at MOZZI_AUDIO_RATE, and / or an appropriate buffer gets used.One additional configuration setting is MOZZI_AUDIO_BITS, which defaults to 16 bits for this mode, but might be set higher, if your hardware supports it.

Mozzi Configuration

-Configuring Mozzi

-

Mozzi configuration options include details such as audio rate, number of audio channels (mono or stereo), output generation method and many others, where details on the available options differ between the different platforms (see Hardware and configuration), and may include additional options beyond those listed, here.

-
Note
It is generally safe to leave the Mozzi Configuration unchanged, and that's very much recommended until you have a very specific need to customize something. Contrary to past versions of Mozzi, all configuration options have a (usually sensible) default value, so you do not have to configure anything, unless you actually want to change something.
-

Configuring Mozzi is mostly done using various preprocessor definitions. This approach is used to move as much of the processing involved to compile time, in order to save Flash, RAM, and CPU use at runtime. This section lists various global options, but in addition, most ports allow additional hardware dependent configuration options. See Hardware and configuration.

-

Several configuration examples are provided in the "config" folder of the Mozzi sources. You may want to look at these, first. The general approach is as follows:

-
#include <MozziConfigValues.h> // include this first, for named option values
-
#define MOZZI_AUDIO_CHANNELS MOZZI_STEREO // set to stereo mode
-
-
#include <Mozzi.h> // *after* all configuration options, include the main Mozzi headers
-
Mozzi.h
This is the main include file in Mozzi.
-
MozziConfigValues.h
This file keeps a list of named configuration values.
-

Alternatively, if a suitable configuration example exists, use:

#include <config/config_example_avr_stereo.h> // again, do this, before including the main headers
-
Note
Should you include Mozzi headers in more than one compilation unit (i.e. more than one .cpp file) inside the same sketch, you must use identical configuration options at the top of each file!

◆ MOZZI_ANALOG_READ

- -
-
- - - - -
#define MOZZI_ANALOG_READ
-
- -

Whether to compile in support for non-blocking analog reads.

-

This is enabled by default on platforms that support it, but may be disabled, explicitly, to save resources, or in order to implement custom read schemes (e.g. with IO multiplexing).

-

For simplicity, mozziAnalogRead() is always defined, but when MOZZI_ANALOG_READ s are disabled or unsupported, it simply relays to Arduino's regular analogRead(). It is thus quite recommended not to depend on mozziAnalogRead() when disabling this.

-

As a rough estimate (your numbers may differ a bit, depending on compiler version, etc.), on an ATMEGA328P (aka Arduino Uno), disabling analog reads saves 33 bytes of RAM and 340 bytes of FLASH. The performance savings are theorized to be neglegible, however.

-

Currently allowed values are:

    -
  • MOZZI_ANALOG_READ_NONE Disabled
    • -
  • MOZZI_ANALOG_READ_STANDARD Analog read implementation enabled (currently there is only the "standard" method, but future versions might allow additional choice, here).

◆ MOZZI_AUDIO_BITS

- -
-
- - - - -
#define MOZZI_AUDIO_BITS
-
- -

Output resolution of audio samples.

-

In most cases you should leave this value untouched (for the defaults that get applied, see Hardware and configuration . However, for MOZZI_AUDIO_MODE s MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM you way wish to customize the default value of 16 bits.

-
Note
At the time of this writng single audio samples are stored as "int", unconditionally. This limits MOZZI_AUDIO_BITS to a maximum of 16 bits on some 8 bit boards!
- -

Definition at line 296 of file mozzi_config_documentation.h.

- -
-
- -

◆ MOZZI_AUDIO_BITS_PER_CHANNEL

- -
-
- - - - -
#define MOZZI_AUDIO_BITS_PER_CHANNEL
-
- -

Only for MOZZI_AUDIO_MODE MOZZI_OUTPUT_2PIN_PWM.

-

Sample resolution per channel to use in 2 pin output, given in bits (i.e. total resolution is twice as much). Defaults to 7 bits per channel. Note that increasing this requires very, very well matched output resistors.

-

See Mozzi on classic Arduino, Teensy 2.x, Arduino Mega, and other 8 bit "AVR"/ATMEGA architecture boards for a more detailed description.

- -

Definition at line 223 of file mozzi_config_documentation.h.

- -
-
- -

◆ MOZZI_AUDIO_CHANNELS

- -
-
- - - - -
#define MOZZI_AUDIO_CHANNELS
-
- -

This sets allows to change from a single/mono audio output channel to stereo output.

-

To actually generate two channels, your updateAudio()-function should return a StereoOutput(). Sketches returning a MonoOutput() in a stereo config, or vice versa will continue to work, but will generate a warning a compile time.

-
Note
This option superseeds the earlier STEREO_HACK in Mozzi < 1.1
-
-At the time of this writing, only MOZZI_MONO and MOZZI_STEREO are supported. The value of MOZZI_MONO is 1 and the value of MOZZI_STEREO is 2, so future extensions are also expected to set this to the number of available channels, and it's ok to use numerical comparison.

◆ MOZZI_AUDIO_INPUT

- -
-
- - - - -
#define MOZZI_AUDIO_INPUT
-
- -

Whether to enable built in audio input feature.

-

This is not supported on all platforms, and on platforms that do support it may come with a considerable performance overhead. Don't enable, unless you need this.

-

Currently allowed values are:

    -
  • MOZZI_AUDIO_INPUT_NONE No audio input
    • -
  • MOZZI_AUDIO_INPUT_STANDARD Audio input enabled (currently there is only the "standard" method, but future versions might allow additional choice, here). This mode implies that MOZZI_ANALOG_READ s are enabled and supported. You may have to call setupFastAnalogReads(FASTEST_ADC) after setupMozzi(), when using this.

◆ MOZZI_AUDIO_INPUT_PIN

- -
-
- - - - -
#define MOZZI_AUDIO_INPUT_PIN
-
- -

This sets which analog input channel to use for audio input, if you have enabled MOZZI_AUDIO_INPUT, above.

-

Not all pins may be available for this, be sure to check the documentation for your platform.

- -

Definition at line 197 of file mozzi_config_documentation.h.

- -
-
- -

◆ MOZZI_AUDIO_MODE

- -
-
- - - - -
#define MOZZI_AUDIO_MODE
-
- -

Configure how Mozzi outputs generated sounds.

-
Note
Not all options are available on all platforms, and several options require specific wiring or external components to function on top of this! When customizing this, it is highly recommended to start experimenting with a simple and known-to-work sketch (such as a basic sinewave) to verify that your hardware setup is correct. Similarly, if you observe problems running your "real" sketch, it is often a good idea ot test your sketch with the default audio mode, too (by leaving this option, and preferrably all others, unset).
-

Refer to the Hardware and configuration specific documentation for which modes are supported on your hardware, and further details!

-

Supported values:

    -
  • MOZZI_OUTPUT_PWM Output using pulse width modulation (PWM) on a GPIO pin. This is the default on most platforms. On the Arduino Uno (more generally ATMEGA328P), this allows for a sample resolution of 488 (almost 9 bits) on pin 9. Usable pins and resolution will be different on other boards.
    • -
  • MOZZI_OUTPUT_2PIN_PWM Output using pulse width modulation on two GPIO pins, where one pin represents the lower bits, and the other the higer bits of the sample. On the Aduino Uno, this allows for 14 bits of resolution on pins 9 (low) and 10 (high). For further information (wiring etc.) see hardware_avr_2pin.
    • -
  • MOZZI_OUTPUT_EXTERNAL_TIMED Output is not controlled by Mozzi itself, but left to the user sketch. This setting allows to completely customize the audio output, e.g. for connecting to external DACs. For more detail, see External audio output
    • -
  • MOZZI_OUTPUT_EXTERNAL_CUSTOM As above, but additionally bypassing Mozzi's sample buffer. For more detail, see External audio output
    • -
  • MOZZI_OUTPUT_PDM_VIA_I2S Output pulse density modulated (PDM) samples via a (hardware) I2S interface (without a DAC connected to it).
    • -
  • MOZZI_OUTPUT_PDM_VIA_SERIAL Output pulse density modulated (PDM) samples via a hardware serial interface.
    • -
  • MOZZI_OUTPUT_I2S_DAC Output samples to a PT8211 (or compatible) DAC connected to a hardware I2S interface.
    • -
  • MOZZI_OUTPUT_INTERNAL_DAC Output to the interal DAC on boards that support one.
    • -
-

◆ MOZZI_AUDIO_PIN_1

- -
-
- - - - -
#define MOZZI_AUDIO_PIN_1
-
- -

Only for MOZZI_AUDIO_MODE s MOZZI_OUTPUT_PWM and MOZZI_OUTPUT_2PIN_PWM: The IO pin to use as (first) audio output.

-

This must be attached to Timer1. When settings this, you alsso need to specify the output compare register responsible for this pin (either OCR1A or OCR1B).

-

Example:

#define MOZZI_AUDIO_PIN_1 TIMER1_B_PIN
-
#define MOZZI_AUDIO_PIN_1_REGISTER OCR1B // must also specify this, when customizing MOZZI_AUDIO_PIN_1
-

Equivalent definitions can be used to control the pin for the right audio channel (in stereo mode), or the low byte channel (in 2 Pin PWM mode):

-
#define MOZZI_AUDIO_PIN_2 [...]
-
#define MOZZI_AUDIO_PIN_2_REGISTER [the matching OCR]
-
// or
-
#define MOZZI_AUDIO_PIN_1_LOW [...]
-
#define MOZZI_AUDIO_PIN_1_LOW_REGISTER [the matching OCR]
-

◆ MOZZI_AUDIO_RATE

- -
-
- - - - -
#define MOZZI_AUDIO_RATE
-
- -

Defines the audio rate, i.e.

-

rate of samples output per second.

-

The default rate on the classis Arduino Uno is 16384 Hz, but can be increased to 32768 Hz, subject to the caveats, detailed below. For most other platforms 32678 Hz is the default, but even higher rates may be supported. Increasing the rate allows for better frequency response, but generally all affects achievable sample bitdepth (especially from PWM output). Also, of course, doubling the sample rate also halves the amount of time available to calculate the each sample, so it may only be useful for relatively simple sketches. The increased frequency response can also make unwanted artefacts of low resolution synthesis calculations more apparent, so it's not always a bonus.

-

It is highly recommended to keep the audio rate a power of two (16384, 32678, 64536, etc.), as some internal calculations can be highly be optimised for speed, this way.

-
Note
For compatibility reasons, the option MOZZI_AUDIO_RATE is automatically set to the same value as this option, and you will find some uses of that in old (pre Mozzi 2.0) code examples. It is advised to use only MOZZI_AUDIO_RATE in new code, however. TODO: Only do the above, for MOZZI_COMPATIBILITY_LEVEL < MOZZI_COMPATIBILITY_2_0?
- -

-
- -

◆ MOZZI_COMPATIBILITY_LEVEL

- -
-
- - - - -
#define MOZZI_COMPATIBILITY_LEVEL
-
- -

Mozzi generally tries to keep your old sketches working, but we continue to find new (and hopefully better) approaches to old problems.

-

Sometimes, keeping API compatibilty with the pre-existing solution may come with a smaller or larger penalty in terms of performance or code size. Therefore - if your sketch supports it - you may be able to get some minor benefit from disabling compatibility code.

-

Currently supported values are:

    -
  • MOZZI_COMPATIBILITY_1_1 - try to support sketches written for Mozzi version 1.1 (or possibly lower); this is the default when including MozziGuts.h
    • -
  • MOZZI_COMPATIBILITY_2_0 - try to support sketches written for Mozzi version 2.0; this is - currently - the default when including Mozzi.h
    • -
  • MOZZI_COMPATIBILITY_LATEST - always live on the bleeding edge
    • -
-
Note
MOZZI_COMPATIBILITY_V1_1 does not guarantee, that everything from Mozzi 1.1 will continue to work, just that we're doing a reasonable effort.

◆ MOZZI_CONTROL_RATE

- -
-
- - - - -
#define MOZZI_CONTROL_RATE
-
- -

Control rate setting.

-

Mozzi's MOZZI_CONTROL_RATE sets how many times per second updateControl() is called. MOZZI_CONTROL_RATE has a default of 64 Hz. It is useful to have MOZZI_CONTROL_RATE set at a power of 2 (such as 64,128,256 etc), to have exact timing of audio and control operations. Non-power-of-2 MOZZI_CONTROL_RATE can cause glitches due to audio and control events not lining up precisely. If this happens a power of two MOZZI_CONTROL_RATE might solve it.

-

Try to keep MOZZI_CONTROL_RATE low, for efficiency, though higher rates up to about 1000 can sometimes give smoother results, avoiding the need to interpolate sensitive variables at audio rate in updateAudio().

-

TODO: If a definition of MOZZI_CONTROL_RATE is detected, apply that with a warning.

- -

Definition at line 148 of file mozzi_config_documentation.h.

- -
-
- -

◆ MOZZI_PWM_RATE

- -
-
- - - - -
#define MOZZI_PWM_RATE
-
- -

Only for MOZZI_AUDIO_MODE s MOZZI_OUTPUT_PWM and MOZZI_OUTPUT_2PIN_PWM.

-

On some platforms, the rate at which PWM signals are repeated may be higher than that at with audio signals are produced (i.e. MOZZI_AUDIO_RATE). E.g. for MOZZI_OUTPUT_PWM on the classic Arduino, the pwm defaults to 32768 while the audio rate defaults to 16384. The reasoning behind this is that 16384 Hz audio rate turned out to be te most useful compromise - in most casses - between output quality, and available computing power. However, output at that rate produced high-frequency whine, audible to some people, which could be mitigated by the higher PWM rate.

-

In other words, increasing this improves the signal quality at less cost than doubling the audio rate itself. However, increasing this too far will limit the dynamic resolution of the samples that can be written to the output pin(s): 2 ^ (output bits) * MOZZI_PWM_RATE cannot be higher than the CPU frequency!

Mozzi Core Functions
-
-
-

Detailed Description

-

The bones of every Mozzi sketch.

-

Sets up the timers for audio and control rate processes, storing the timer registers so they can be restored when Mozzi stops. startMozzi() goes in your sketch's setup() routine.

-

This function intializes the timer(s) needed to move audio samples to the output according to the configured MOZZI_AUDIO_MODE .

-
Parameters
- - -
control_rate_hzSets how often updateControl() is called. It must be a power of 2. If no parameter is provided, control_rate_hz is set to MOZZI_CONTROL_RATE, which has a default value of 64 (you can re-#define it in your sketch). The practical upper limit for control rate depends on how busy the processor is, and you might need to do some tests to find the best setting.
-
-
-
Note
startMozzi calls setupMozziADC(), which calls setupFastAnalogRead() and adcDisconnectAllDigitalIns(), which disables digital inputs on all analog input pins. All in mozzi_analog.h and easy to change if you need to (hack). They are all called automatically and hidden away because it keeps things simple for a STANDARD_PLUS set up, but if it turns out to be confusing, they might need to become visible again.

◆ CONSTTABLE_STORAGE

- -
-
- - - - - - - - -
#define CONSTTABLE_STORAGE( X)
-
- -

Declare a variable such that it will be stored in flash memory, instead of RAM, on platforms where this is reasonably possible (i.e.

-

not on ESP8266, where random location flash memory access is too slow). To read the variable in a cross-platform compatible way, use FLASH_OR_RAM_READ().

Function Documentation

- -

◆ audioHook()

- -
-
- - - - - - - -
void audioHook ()
-
- -

This is required in Arduino's loop().

-

If there is room in Mozzi's output buffer, audioHook() calls updateAudio() once and puts the result into the output buffer. Also, if @ref MOZZI_AUDIO_INPUT is enabled in the config, audioHook() takes care of moving audio input from the input buffer so it can be accessed with getAudioInput() in your updateAudio() routine. If other functions are called in loop() along with audioHook(), see if they can be called less often by moving them into updateControl(), to save processing power. Otherwise it may be most efficient to calculate a block of samples at a time by putting audioHook() in a loop of its own, rather than calculating only 1 sample for each time your other functions are called.

- -

Definition at line 313 of file MozziGuts.hpp.

- -
-
- -

◆ audioTicks()

- -
-
- - - - - - - -
unsigned long audioTicks ()
-
- -

An alternative for Arduino time functions like micros() and millis().

-

This is slightly faster than micros(), and also it is synchronized with the currently processed audio sample (which, due to the audio output buffer, could diverge up to 256/MOZZI_AUDIO_RATE seconds from the current time). audioTicks() is updated each time an audio sample is output, so the resolution is 1/MOZZI_AUDIO_RATE microseconds (61 microseconds when MOZZI_AUDIO_RATE is 16384 Hz).

Returns
the number of audio ticks since the program began.
- -

Definition at line 301 of file MozziGuts.hpp.

- -
-
- -

◆ FLASH_OR_RAM_READ()

- -
-
-
-template<typename T >
- - - - - -
- - - - - - - - -
T FLASH_OR_RAM_READ (T * address)
- 		-inline
-
- -

Read a value from flash or RAM.

-

The specified address is read from flash, if T is const, and const tables are stored in flash on this platform (i.e. not on ESP8266). It is read from RAM, if T is not-const or tables are always stored in RAM on this platform.

- -

◆ mozzi_pgm_read_wrapper()

- -
-
-
-template<typename T >
- - - - - -
- - - - - - - - -
T mozzi_pgm_read_wrapper (const T * address)
- 		-inline
-
- -

Helper function to FLASH_OR_RAM_READ().

-

You do not want to call this, directly.

- -

Definition at line 32 of file mozzi_pgmspace.h.

- -
-
- -

◆ mozziMicros()

- -
-
- - - - - - - -
unsigned long mozziMicros ()
-
- -

An alternative for Arduino time functions like micros() and millis().

-

This is slightly faster than micros(), and also it is synchronized with the currently processed audio sample (which, due to the audio output buffer, could diverge up to 256/MOZZI_AUDIO_RATE seconds from the current time). audioTicks() is updated each time an audio sample is output, so the resolution is 1/MOZZI_AUDIO_RATE microseconds (61 microseconds when MOZZI_AUDIO_RATE is 16384 Hz).

Returns
the approximate number of microseconds since the program began.
- -

Definition at line 300 of file MozziGuts.hpp.

- -
-
- -

◆ stopMozzi()

- -
-
- - - - - - - -
void stopMozzi ()
-
- -

Stops audio and control interrupts and restores the timers to the values they had before Mozzi was started.

-

This could be useful when using sensor libraries which depend on the same timers as Mozzi.

-

A potentially better option for resolving timer conflicts involves using non-blocking methods, such as demonstrated by the twowire_nonblock code in the forked version of Mozzi on github, so sound production can continue while reading sensors.

-

As it is, stopMozzi restores all the Timers used by Mozzi to their previous settings. Another scenario which could be easily hacked in MozziGuts.hpp could involve individually saving and restoring particular Timer registers depending on which one(s) are required for other tasks.

-
Note
This function is not actually implemented on all platforms.
- -

Definition at line 303 of file MozziGuts.hpp.

- -
-
- -

◆ updateAudio()

- -
-
- - - - - - - -
AudioOutput updateAudio ()
-
- -

This is where you put your audio code.

-

updateAudio() has to keep up with the MOZZI_AUDIO_RATE of 16384 or 32768 Hz, so to keep things running smoothly, avoid doing any calculations here which could be done in setup() or updateControl().

Returns
an audio sample.
-

While is possible (in mono sketches) to return a plain unscaled int, it is generally best to return auto-scaled samples using MonoOutput::from8Bit(), MonoOutput::from16Bit(), MonoOutput::fromNbit(), or their StereoOutput equivalents.

- -

Definition at line 5 of file Skeleton_Multi_Unit2.cpp.

- -
-
- -

◆ updateControl()

- -
-
- - - - - - - -
void updateControl ()
-
- -

This is where you put your control code.

-

You need updateControl() somewhere in your sketch, even if it's empty. updateControl() is called at the control rate you set in startMozzi(). To save processor load, avoid any calculations here which could be done in setup().

Fast integer based fixed-point arithmetic

Detailed Description

-
Note
For new sketches it is recommended to utitlize the FixMath library with its typesafe classes UFix and SFix, instead of these typedefs! See https://github.com/tomcombriat/FixMath . These are provided for backwards compatibility, only.
-

Fixed point fractional number types and conversion routines. Fixed point is often best for fast audio code for Arduino, and these can ease some of the pain.

-
-
Note
-

Take care when converting that the important bits of your numbers will fit in the types you choose!

-

Timing: converting between fixed and float 10-12us, converting between fixed types about 1us.

◆ mtof() [1/6]

- -
-
- - - - - -
- - - - - - - - -
float mtof (float midival)
- 		-inline
-
- -

Converts midi note number to frequency.

-

Caution: this can take up to 400 microseconds to run. It can seriously mess up the audio output if you use it in updateControl() or updateAudio(). This is a good choice in setup(), or where you need precise midi-pitch conversion and aren't doing much other audio calculation.

Note
Beware this returns an invalid result for midi note 0.
-
-Timing: ~350 us
-
Parameters
- - -
midivala midi note number, 1.0 or greater. Like the mtof object in Pd, midi values can have fractions.
-
-
-
Returns
the frequency represented by the input midi note number..

◆ Q16n16_mtof()

- -
-
- - - - - -
- - - - - - - - -
Q16n16 Q16n16_mtof (Q16n16 midival_fractional)
- 		-inline
-
- -

Converts midi note number to frequency with speed and accuracy.

-

Q16n16_mtofLookup() is a fast alternative to (float) mtof(), and more accurate than (uint8_t) mtof(), using Q16n16 fixed-point format instead of floats or uint8_t values. Q16n16_mtof() uses cheap linear interpolation between whole midi-note frequency equivalents stored in a lookup table, so is less accurate than the float version, mtof(), for non-whole midi values.

Note
Timing: ~8 us.
-
Parameters
- - -
midival_fractionala midi note number in Q16n16 format, for fractional values.
-
-
-
Returns
the frequency represented by the input midi note number, in Q16n16 fixed point fractional integer format, where the lower word is a fractional value.

◆ randSeed() [1/2]

- -
-
- - - - - -
- - - - - - - -
void randSeed ()
- 		-inline
-
- -

Initialises Mozzi's (pseudo)random number generator xorshift96(), which is used in Mozzi's rand() function.

-

This can be useful if you want random sequences to be different on each run of a sketch, by seeding with a fairly random input. randSeed() called without a parameter uses noise from reading the Arduino's internal temperature as the seed, a technique discussed at http://arduino.cc/forum/index.php/topic,38091.0.html, borrowing code put there by Rob Tillaart.

-
Note
Intialization of the random seed is done differently on different MCUs, but is nowhere near perfect for most (and for some it is not even implemented at all). Many implementations (e.g. on AVR, STM32) simply rely on reading a (hopefully noisy) internal temperature sensor. You will often get better results by calling analogRead() - not mozziAnalogRead(0), in this case! - on one or two floating (non-connected) analog pins.

void randSeed (uint32_t seed)
- 		-inline
-
- -

Initialises Mozzi's (pseudo)random number generator xorshift96(), which is used in Mozzi's rand() function.

-

This can be useful if you want random sequences to be different on each run of a sketch, by seeding with fairly random input, such as analogRead() on an unconnected pin (as explained in the Arduino documentation for randomSeed(). randSeed is the same as xorshift96Seed(), but easier to remember.

◆ OverSample

- -
-
- - - - -
class OverSample
-
-

template<class T, const uint8_t RESOLUTION_INCREASE_BITS>
-class OverSample< T, RESOLUTION_INCREASE_BITS >

- -

Enables the resolution of analog inputs to be increased by oversampling and decimation.

-

Noise should be added to the input before it's digitised, then a succession of input readings are summed and finally divided to give a number with greater resolution than the ADC.
- Often, noise in the Arduino system will be enough, but there are other practical methods described in Enhancing ADC Resolution by Oversampling, as well as an explanation of the overall approach.

Template Parameters
- - -
RESOLUTION_INCREASE_BITShow many extra bits of resolution to produce. The window length and the memory it needs increases quickly as the oversampling resolution increases.
- 1 bit = 4 unsigned ints (analog input between 0-1023) = 8 uint8_ts, 2 bits = 16 unsigned ints = 32 uint8_ts,
- 3 bits = 64 unsigned ints = 128 uint8_ts, More than 3 bits increase in resolution would require either using longs to store the readings, which would need 1024 uint8_ts for a 4 bit increase and 4096 uint8_ts for 5 bits (do any avr's have that much room?), or the average reading would have to be no more than 128 (for 4 bits increase), because 256 readings would be needed, and the sum of all 256 readings would have to fit into an int. (32767 / 256 = 128). Changing OverSample to use unsigned ints could enable an average reading of 256, but isn't tested properly yet.
-
-
-
Note
The higher the resolution, the more lag there will be. It's almost a RollingAverage filter, with the difference that OverSample doesn't divide by as much as you would for an average.

Look-up-tables and python scripts to generate tables or convert sounds.

-

Includes ready-to-use wave tables and a few example samples which are in the Mozzi/tables and Mozzi/samples folders. You can convert your own sounds from a program like Audacity to tables for Mozzi with a script called char2mozzi.py, in Mozzi/python. Read the int8_t2mozzi.py file for instructions. Also check out the other scripts in the python folder for templates to use if you want to do your own thing.

For example, this is used in StateVariable.h to choose a different next() function for each kind of filter, LOWPASS, BANDPASS, HIGHPASS or NOTCH, which are simple integer values 0,1,2,3 provided to the StateVariable template on instantiation. Fantastic! It's in C++11, but not yet available in avr-gcc. See "c++ enable_if"

Mozzi on classic Arduino, Teensy 2.x, Arduino Mega, and other 8 bit "AVR"/ATMEGA architecture boards

-Port status and notes

-

This is the original "port" of Mozzi, and thus very elaborate. The main challenges on this platform, compared to other MCUs, are limitations in flash, RAM, and CPU power.

-

-Output modes

-

The following audio modes (see MOZZI_AUDIO_MODE) are currently supported on this hardware:

    -
  • MOZZI_OUTPUT_PWM
    • -
  • MOZZI_OUTPUT_2PIN_PWM
    • -
  • MOZZI_OUTPUT_EXTERNAL_TIMED
    • -
  • MOZZI_OUTPUT_EXTERNAL_CUSTOM
    • -
-

In all modes, except MOZZI_OUTPUT_EXTERNAL_CUSTOM, Timer 1 is claimed, and is not available for any other purpose. This means, among other things, that pins 9 and 10 cannot be used for analogWrite(), while pins 3 and 11 should still be available except in MOZZI_OUTPUT_2PIN_PWM mode (as Timer2 is also claimed, then; for definite info on which pin is connected to which timer, check a suitable reference, as your board may differ). See Mozzi>examples>11.Communication>Sinewave_PWM_pins_HIFI. for an example of emulating analogWrite() on any digital pin, without the need for a hardware timer.

-

-MOZZI_OUTPUT_PWM

-

For MOZZI_OUTPUT_PWM, output is restricted to pins that are hardware-attached to Timer 1, but can be configured within this tight limit. In particular, the default setup on the Arduino UNO is:

    -
  • Mono: Pin 9 -> configurable using MOZZI_AUDIO_PIN_1
    • -
  • Stereo: Pin 9 (left) and Pin 10 (right) -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_2 For pinouts on other boards, refer to config/known_16bit_timers.
    • -
-

Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE: MOZZI_PWM_RATE.

-

The available sample resolution is 488, i.e. almost 9 bits, providing some headroom above the 8 bit table resolution currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.

-

-MOZZI_OUTPUT_2PIN_PWM

-

In this mode, output is split across two pins (again, both connected to Timer 1), with each outputting 7 bits for a total of 14. This allows for much better dynamic range, providing much more definition than can be achieved using MOZZI_OUTPUT_PWM , while using only modestly more processing power. Further, it allows for a much higher PWM carrier rate can be much higher (125 kHz by default; see MOZZI_PWM_RATE), which is well beyond the audible range.

-

On the downside, this mode requires an extra hardware timer (Timer2 in addition to Timer1), which may increase compatibility problems with other Arduino libraries that also require a timer. Further, a more elaborate hardware setup is needed, making it less convenient for rapid prototyping. For circuit details, see https://sensorium.github.io/Mozzi/learn/output/ .

-

On the classic Arduino Uno, the default pinout in this mode is:

    -
  • Pin 9 (high bits) and Pin 10 (low bits) -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_1_LOW
    • -
-

Here is table of the default pins on some other boards. Rows with an x on it have actually been tested (and importantly, the outcome recoreded; input welcome on further boards.)

-

-.............B5(14)...B6(15)...........Teensy2
-x...........B5(25)...B6(26)...........Teensy2++
-.................13.........12...............Sanguino
- For pinouts on other AVR boards, config/known_16bit_timers might contain some hints.

-

Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE, and is much higher (125kHz), by default: MOZZI_PWM_RATE.

-

The default sample resolution is 7 bits per pin, for a total of 14 bits. This can be configured within hardware limits (MOZZI_PWM_RATE) using MOZZI_AUDIO_BITS_PER_CHANNEL, but beware that increasing this will require even more accuracy in our output resistors (see the linked documentation, above).

port by Dieter Vandoren and Thomas Friedrichsmeier

-

-Port status and notes

-
    -
  • Since flash memory is not built into the ESP32, but connected, externally, it is much too slow for keeping wave tables, audio samples, etc. Instead, these are kept in RAM on this platform.
    • -
  • Asynchronous analog reads are not implemented. mozziAnalogRead() relays to analogRead(). MOZZI_AUDIO_INPUT is not implemented
    • -
  • twi_nonblock is not ported
    • -
  • WIFI-activity not yet tested, but likely the same notes as for ESP8266 apply, i.e. any Wifi activity is likely to introdcue considerable nose. Consider turning off WIFI.
    • -
  • The implementation of audioTicks() may be slightly inaccurate on this platform.
    • -
-

-Output modes

-

The following audio modes (see MOZZI_AUDIO_MODE) are currently supported on this hardware:

    -
  • MOZZI_OUTPUT_EXTERNAL_TIMED
    • -
  • MOZZI_OUTPUT_EXTERNAL_CUSTOM
    • -
  • MOZZI_OUTPUT_PDM_VIA_I2S
    • -
  • MOZZI_OUTPUT_I2S_DAC
    • -
  • MOZZI_OUTPUT_INTERNAL_DAC
    • -
-

The default mode is MOZZI_OUTPUT_INTERNAL_DAC .

-

-MOZZI_OUTPUT_INTERNAL_DAC

-

The internal DAC has 8 bit resolution, and outputs to GPIO pins 25 and 26 (non-configurable). For simplicity of code, both pins are always used. In a mono configuration, both pins output the same sample.

-

TODO: We could really use this to hack in a 2 PIN mode!

-
Note
The number 25 refers to "GPIO 25" or sometimes labelled "D25". Confusingly, many boards come with an additional, totally different numbering scheme on top of that. Check a detailed pinout diagram, if in any doubt.
-

Internally, the inbuilt DAC is connected via an I2S interface. Which interface number to use can be configured using:

-
#define MOZZI_I2S_PORT ... // (default: I2S_NUM_0)
-

-MOZZI_OUTPUT_I2S_DAC

-

This mode outputs to a PT8211 (or compatible) I2S DAC, which allows for very high quality (mono or stereo) output. Communication needs the BCK, WS, and DATA(out) pins of one I2S interface. Presumably, any pins qualify, and you can configure this using:

#define MOZZI_I2S_PIN_BCK ... // (default: 26)
-
#define MOZZI_I2S_PIN_WS ... // (default: 15)
-
#define MOZZI_I2S_PIN_DATA ... // (default: 33)
-
#define MOZZI_I2S_PORT ... // (default: I2S_NUM_0)
-

See the note above (esp_internal_dac) regarding pin numbering. Also, please always test the default pinout, should a custom setting fail!

-

As a technical note, I2S support in the ESP32 SDK has been reworked since this was implemented in Mozzi, and Mozzi uses the "legacy" implementation "i2s.h". This should not be an issue, unless you want to connect additional I2S components, yourself. In which case contributions are certainly welcome!

-

-MOZZI_OUTPUT_PDM_VIA_I2S

-

This mode uses the same setup as MOZZI_OUTPUT_I2S_DAC, but rather than using an external DAC, the communication signal itself is modulated in PDM (pulse density modulation) encoded form. Thus not extra hardware is needed, and the signal is output on the DATA pin (see above). The BCK and WS pins are also claimed, but should be left non-connected, and do not produce anything meaningful. This can only be used in mono mode.

-

Output resolution may be adjusted by defining MOZZI_PDM_RESOLUTION , where the default value of 4 means that each audio sample is encoded into four 32 bit blocks of ones and zeros. Obviously, more is potentially better, but at the cost of considerable computation power.

    • -
  • Asynchronous analog reads are not implemented. mozziAnalogRead() relays to analogRead(). MOZZI_AUDIO_INPUT is not available
    • -
  • twi_nonblock is not ported
    • -
  • Note that the ESP8266 pins can output less current than the other supported CPUs. The maximum is 12mA, with a recommendation to stay below 6mA.
      -
    • WHEN CONNECTING A HEADPHONE, DIRECTLY, USE APPROPRIATE CURRENT LIMITING RESISTORS (>= 500Ohms).
      • -
    -
    • -
  • Any WiFi-activity can cause severe spikes in power consumption. This can cause audible "ticking" artifacts, long before any other symptoms.
      -
    • If you do not require WiFi in your sketch, you should turn it off, explicitly, using
      WiFi.mode(WIFI_OFF)
      -
      .
      • -
    -
    • -
  • A juicy enough, well regulated power supply, and a stabilizing capacitor between VCC and Gnd can help a lot.
    • -
  • As the (PDM) output signal is digital, a single (fast!) transistor can be used to amplify it to an independent voltage level.
    • -
  • audioHook() calls yield() once for every audio sample generated. Thus, as long as your audio output buffer does not run empty, you should not need any additional yield()s inside loop().
    • -
-

-Output modes

-

The following audio modes (see MOZZI_AUDIO_MODE) are currently supported on this hardware:

    -
  • MOZZI_OUTPUT_EXTERNAL_TIMED
    • -
  • MOZZI_OUTPUT_EXTERNAL_CUSTOM
    • -
  • MOZZI_OUTPUT_PDM_VIA_I2S
    • -
  • MOZZI_OUTPUT_PDM_VIA_SERIAL
    • -
  • MOZZI_OUTPUT_I2S_DAC
    • -
-

The default mode is MOZZI_OUTPUT_PDM_VIA_SERIAL .

-
Note
This port really does not currently come with a PWM mode!
-

-MOZZI_OUTPUT_PDM_VIA_SERIAL

-

Output is coded using pulse density modulation, and sent via GPIO2 (Serial1 TX).

    -
  • This output mode uses timer1 for queuing audio sample, so that timer is not available for other uses.
    • -
  • Note that this mode has slightly lower effective analog output range than esp8266_pdm_via_i2s, due to start/stop bits being added to the output stream.
    • -
  • Supports mono output, only, pins not configurable.
    • -
-

The option MOZZI_PDM_RESOLTUON (default value 2, corresponding to 64 ones and zeros per audio sample) can be used to adjust the output resolution. Obviously higher values demand more computation power.

-

-MOZZI_OUTPUT_PDM_VIA_SERIAL

-

Output is coded using pulse density modulation, and sent via the I2S pins. The I2S data out pin (GPIO3, which is also "RX") will have the output, but all I2S output pins (RX, GPIO2 and GPIO15) will be affected. Mozzi tries to set GPIO2 and GPIO15 to input mode, and at the time of this writing, this allows I2S output on RX even on boards such as the ESP01 (where GPIO15 is tied to Ground). However, it seems safest to assume that this mode may not be useable on boards where GPIO2 or GPIO15 are not available as output pins.

-

Supports mono output, only, pins not configurable.

-

Resolution may be controlled using MOZZI_PDM_RESOLUTION (see above; default value is 2).

-

-MOZZI_OUTPUT_I2S_DAC

-

Output is sent to an external DAC (such as a PT8211), digitally coded. This is the only mode that supports stereo (MOZZI_AUDIO_CHANNELS). It also needs the least processing power. The pins cannot be configured (GPIO3/RX, GPIO2, and GPIO15).

port by Thomas Friedrichsmeier & Thomas Combriat

-

-Port status and notes

-

Compiles and runs using Arduino's standard and Arduino_AdvancedAnalog libraries. This port is still experimental, testing reveals some instabilities for some configurations (in particular with MOZZI_AUDIO_INPUT) that are under active investigations.

-

This port is not complete yet, in particular:

    -
  • Asynchroneous analog reads are not implemented (yet), mozziAnalogRead() relays to analogRead(). (Note that MOZZI_AUDIO_INPUT is implemented!)
    • -
  • This port should support other MBED based Arduino boards like the Arduino Portenta, in theory, but the developer have only tested it on the Giga. Feedback welcome!

-Output modes

-

The following audio modes (see MOZZI_AUDIO_MODE) are currently supported on this hardware:

    -
  • MOZZI_OUTPUT_EXTERNAL_TIMED
    • -
  • MOZZI_OUTPUT_EXTERNAL_CUSTOM
    • -
  • MOZZI_OUTPUT_PDM_VIA_SERIAL
    • -
  • MOZZI_OUTPUT_INTERNAL_DAC
    • -
-

The default mode is MOZZI_OUTPUT_INTERNAL_DAC .

-

-MOZZI_OUTPUT_INTERNAL_DAC

-

This uses the inbuild DAC on the board. The default is setting is appropriate for the Arduino Giga: 12 bits going to A13 (3.5mm jack connector's tip), and in stereo mode to pin A12 (3.5mm jack connector's first ring) additionally.

-

For other boards is may be appropriate to customize:

#define MOZZI_AUDIO_PIN_1 ... // mono / left channel; default: A13
-
#define MOZZI_AUDIO_PIN_2 ... // stereo only: right channel; default: A12
-
#define MOZZI_AUDIO_BITS ... // default is 12
-

-MOZZI_PDM_VIA_SERIAL

-

Returns a pulse-density modulated (mono only) signal on one of the hardware UARTs of the board (Serial ports). Default is using the SERIAL2, on pin D18. You can confiugre the pins to use, but it must be connected to a hardware UART. Output is written to the TX pin, only, but the RX pin needs to be claimed as well. Beware of confusing pinout labelling, for instance SERIAL2_TX iss labelled "TX1" on the Arduino Giga. The audio resolution can be enhanced using MOZZI_PDM_RESOLUTION, which is described in more detail here: @esp32_pdm_via_i2s .

-

Configuration options:

#define MOZZI_SERIAL_PIN_TX ... // default: SERIAL2_TX
-
#define MOZZI_SERIAL_PIN_RX ... // *must* specify the matching one, if customizing the above; default: SERIAL2_RX
-
#define MOZZI_PDM_RESOLUTION ... // default value is 2, for 2*32 ones and zeros per audio sample
-

Mozzi on Arduino Uno R4 - Renesas.
-
-
-

port by Thomas Combriat

-

-Port status and notes

-

Compiles and runs using Arduino's standard library (Renesas 0.8.7 at the time of this writing).

-

A few particularities:

    -
  • Because this board has an on-board DAC (A0), but only one, STEREO is not implemented and Mozzi uses this pin. Usage of other pins using PWM for instance is not implemented yet.
    • -
  • getAudioInput() and mozziAnalogRead() return values in the Renesas' full ADC resolution of 0-16384 rather than AVR's 0-1023. This might change in the near future for speed purposes.
    • -
-

-Output modes

-

The following audio modes (see MOZZI_AUDIO_MODE) are currently supported on this hardware:

    -
  • MOZZI_OUTPUT_EXTERNAL_TIMED
    • -
  • MOZZI_OUTPUT_EXTERNAL_CUSTOM
    • -
  • MOZZI_OUTPUT_INTERNAL_DAC
    • -
-

The default mode is MOZZI_OUTPUT_INTERNAL_DAC. Further modes may be added in the future.

-

-MOZZI_OUTPUT_INTERNAL_DAC

-

This uses the inbuild DAC on the board on pin A0. Mono output only, and the pin is not configurable. Audio resolution is also fixed at 12 bits (which is what the board supports).

-

This mode claims two timers (but it is not hardcoded, which ones).

-

-MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM

-

MOZZI_OUTPUT_EXTERNAL_TIMED claimes one timer, MOZZI_OUTPUT_EXTERNAL_CUSTOM does not claim any timer. See External audio output

Mozzi on RP2040 (Raspberry Pi Pico)
-
-
-

port by Thomas Friedrichsmeier

-

-Port status and notes

-

Compiles and runs using this core. Can probably be ported to the Mbed core for RP2040, relatively easily, as it relies mostly on the RP2040 SDK API. Tested on a Pi Pico.

-
    -
  • This is a recent addition, implementation details may still change (currently just PWM driven by a timer; this may be worth changing to a DMA driven output)
    • -
  • Wavetables and samples are not kept in progmem on this platform. While apparently speed (of the external flash) is not much of an issue, the data always seems to be copied into RAM, anyway.
    • -
  • Note that getAudioInput() and mozziAnalogRead() return values in the RP2040's full ADC resolution of 0-4095 rather than AVR's 0-1023.
    • -
  • twi_nonblock is not ported
    • -
  • Code uses only one CPU core
    • -
-

-Output modes

-

The following audio modes (see MOZZI_AUDIO_MODE) are currently supported on this hardware:

    -
  • MOZZI_OUTPUT_EXTERNAL_TIMED
    • -
  • MOZZI_OUTPUT_EXTERNAL_CUSTOM
    • -
  • MOZZI_OUTPUT_PWM
    • -
  • MOZZI_OUTPUT_I2S_DAC
    • -
-

The default mode is MOZZI_OUTPUT_PWM .

-

-MOZZI_OUTPUT_PWM

-

Audio output is written to pin 0 (mono) or 0 and 1 (stereo), by default, with 11 bits of ouput resolution. One hardware timer interrupt and one DMA channel are claimed (number not hardcoded), a non-exclusive handler is installed on DMA_IRQ_0.

-

Configuration options:

#define MOZZI_AUDIO_PIN_1 ... // default is 0
-
#define MOZZI_AUDIO_BITS ... // output resolution (bits); default is 11
-
// additionally, for stereo:
-
#define MOZZI_AUDIO_PIN_2 ... // default is 1; this must be on the same PWM slice as the first pin (i.e. neighboring)
-

-MOZZI_OUTPUT_I2S_DAC

-

Output to an external DAC, connected via I2S. This uses 16 bit (per audio channel), but can be changed to 8, 16, 24 (left aligned) and 32 resolution. Both plain I2S and LSBJ format (PT8211 needs this, for instance) are available. Plain format is used by default. The GPIO pins to use can be configured,

    -
  • almost - freely (see below). Two DMA channels are claimed (numbers not hardcoded), non-exclusive handlers are installed on DMA_IRQ_0.
    • -
-

Configuration options:

#define MOZZI_AUDIO_BITS ... // available values are 8, 16 (default), 24 (LEFT ALIGN in 32 bits type!!) and 32 bits
-
#define MOZZI_I2S_PIN_BCK ... // /BLCK) default is 20
-
//#define MOZZI_I2S_PIN_WS (MOZZI_I2S_PIN_BCK+1) ... // CANNOT BE CHANGED, HAS TO BE NEXT TO pBCLK, i.e. default is 21
-
#define MOZZI_I2S_PIN_DATA ... // (DOUT) default is 22
-
#define MOZZI_I2S_FORMAT ... // may be MOZZI_I2S_FORMAT_LSBJ or MOZZI_I2S_FORMAT_PLAIN (default)
-
Note
The MOZZI_I2S_FORMAT_LSBJ option may require a relatively recent git-hub checkout of the arduino-pico core.

Mozzi on STM32-based boards - disambiguation
-
-
-
    -
  • The situation on STM32-based boards is rather confusing, as there are several competing Arduino cores. Importantly:
      -
    • Some boards use dedicated cores (e.g. Arduino Giga / Portenta Mozzi on MBED-based boards (Arduino Giga / Portenta).) etc. For those, see the relevant sections (if we support them).
      • -
    • There is a series of libmaple-based cores, including Roger Clark's libmaple-based core. These are highly optimized, and provide very complete support, but only for a limited number of boards. Unfortunately, at the time of this writing (2023/04), they are not available for installation via the Arduino Board Manager, and they do not currently seem actively maintained. For using these with Mozzi, see Mozzi on STM32-boards with libmaple based core.
      • -
    • A generic Arduino core for STM32 is the STM32duino core. It supports a huge set of boards, and seems to have offical backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what the libmaple cores above were known by (don't blame Mozzi for this mess!). For using this with Mozzi, see Mozzi on STM32duino-based boards.

-This port may look similar to, but uses a different default GPIO pinout than @hardware_stm32duino !
-

-Status and peculiarities of this port

-

Compiles for and runs on a STM32F103C8T6 blue pill board, with a bunch of caveats (see below), i.e. on a board without a real DAC. Should probably run on any other board supported by Roger Clark's libmaple-based core (although this theory is untested).

-
Note
that at the time of this writing, Stev Strong's slightliy more recent fork of this core does not work with Mozzi, apparently due to a bug in pwmWrite().

    -
  • If you want to use MIDI, be sure to replace "MIDI_CREATE_DEFAULT_INSTANCE()" with "MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI)" (or Serial2)
    • -
  • MOZZI_AUDIO_INPUT_STANDARD is implemented in theory, but untested (feedback welcome)
    • -
  • getAudioInput() and mozziAnalogRead() return values in the STM32's full ADC resolution of 0-4095 rather than AVR's 0-1023.

-Output modes

-

The following audio modes (see MOZZI_AUDIO_MODE) are currently supported on this hardware:

    -
  • MOZZI_OUTPUT_EXTERNAL_TIMED
    • -
  • MOZZI_OUTPUT_EXTERNAL_CUSTOM
    • -
  • MOZZI_OUTPUT_PWM
    • -
  • MOZZI_OUTPUT_PWM_2PIN
    • -
-

The default mode is MOZZI_OUTPUT_PWM .

-

-MOZZI_OUTPUT_PWM

-

Standard pulse width modulated output to one (mono) or two (stereo, see MOZZI_AUDIO_CHANNELS) GPIO pins. Default pinout: PB8 (mono/left), PB9 (right channel in stereo). This mode uses two hardware timers: One for the PWM (Timer 4 when using the default pin configuration), and a second for updating the output at audio rate. The default audio resolution is 10 bits, which results in a carrier frequency of ~70kHz on a 72MHz CPU. On slower boards you will have to descrease this. The following settings may be costumized, if desired:

-
#define MOZZI_AUDIO_PIN_1 ... // Left / mono output pin. Default: PB8
-
#define MOZZI_AUDIO_PWM_TIMER ... // Must be set ot the hardware timer connected to the above pin. Default: 4
-
#define MOZZI_AUDIO_UPDATE_TIMER ... // Second hardware timer to claim. Default 2
-
#define MOZZI_AUDIO_BITS ... // Output resolution in bits. Default is 10
-
// For stereo, only:
-
#define MOZZI_AUDIO_PIN_2 ... // Right channel output pin. This *must* be connected to the same hardware timer as MOZZI_AUDIO_PIN_1 ! Default: PB9
-

-MOZZI_OUTPUT_2PIN_PWM

-

This mode is very similar to MOZZI_OUTPUT_PWM, but splitting output for a single channel across two GPIO pins for better resolution. For details on the required hardware setup, and configuration tradeoffs, see MOZZI_OUTPUT_2PIN_PWM . Stereo output is not available in this mode. Output is at 2*7 bits at up to 560kHz carrier frequency (but limited to 5 times audio rate).

-

Customizable configuration options:

#define MOZZI_AUDIO_PIN_1 ... // High byte of the output. Default: PB8
-
#define MOZZI_AUDIO_PIN_2 ... // Low byte of the output. Default: PB9
-
#define MOZZI_AUDIO_PWM_TIMER ... // Must be set to the number of the hardware timer connect to the above pins. Default: 4
-
#define MOZZI_AUDIO_UPDATE_TIMER ... // Second hardware timer to claim. Default TIM2
-
#define MOZZI_AUDIO_BITS_PER_CHANNEL ... // Bits per pin. Default is 7
-

-MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM

-

See External audio output The (single) hardware timer claimed for MOZZI_OUTPUT_EXTERNAL_TIMED may be configured using "MOZZI_AUDIO_UPDATE_TIMER" (default: TIM2).

Tested on a STM32F103C8T6 blue pill board as well as an STM32F411CE black pill board, i.e. on sboards without a real DAC. Compiles and runs, with a bunch of caveats (see below). Should probably run on any other board supported by the STM32duino core (although this theory is untested). When trying any other board, you probably want to check the platform specific settings (see below), carefully, importantly, whether the desired output resolution is achievable, and whether the desired output pins are PWM capable.

This port requires the following two libraries (which should be part of a default installtion, however):

-

Some of the differences for Teensy 3.* which will affect users include:

    -
  • twi_nonblock code by Marije Baalman for non-blocking I2C is not compatible with Teensy 3.0/3.1/3.2.
    • -
-

-Output modes

The default mode is MOZZI_OUTPUT_INTERNAL_DAC .

-

-MOZZI_OUTPUT_INTERNAL_DAC

-

Output is to the inbuilt DAC. Output resolution is 12 bits. Mono, only. The DAC output pin differs from board to boards. In most cases the appropriate pin will be set outmatically. If needed, you can specify the DAC pin, explicitly:

-
#define MOZZI_AUDIO_PIN_1 ... // Default: A14, A12, or A21, depending on board

-
68 
-
69 The DIDR (Data Input Disable Register) disconnects the digital inputs from

70 whichever ADC channels you are using. This is important for 2 reasons. First

71 off, an analog input will be floating all over the place, and causing the
-
72 digital input to constantly toggle high and low. This creates excessive noise
-
73 near the ADC, and burns extra power. Secondly, the digital input and associated
-
74 DIDR switch have a capacitance associated with them which will slow down your
-
75 input signal if you are sampling a highly resistive load.
-
76 
-
77 And from the ATmega328p datasheet, p266:
-
78 
-
79 When an analog signal is applied to the ADC pin and the digital input from
-
80 this pin is not needed, this bit should be written logic one to reduce power
-
81 consumption in the digital input buffer. Note that ADC named_pins ADC7
-
82 and ADC6 do not have digital input buffers, and therefore do not require
-
83 Digital Input Disable bits.

-
10  *
-
11  * Mozzi configuration options include details such as audio rate, number of audio channels (mono or stereo), output generation method and many others,
-
12  * where details on the available options differ between the different platforms (see @ref hardware), and may include additional options beyond those listed, here.
-
13  *
-
14  * @note
-
15  * It is generally safe to leave the Mozzi Configuration unchanged, and that's very much recommended _until_ you have a very specific need to customize something.
-
16  * Contrary to past versions of Mozzi, all configuration options have a (usually sensible) default value, so you do not have to configure _anything_, unless you
-
17  * actually want to change something.
-
18  *
-
19  * Configuring Mozzi is mostly done using various preprocessor definitions. This approach is used to move as much of the processing involved to compile time, in order
-
20  * to save Flash, RAM, and CPU use at runtime. This section lists various global options, but in addition, most ports allow additional hardware dependent
-
21  * configuration options. See @ref hardware.
-
22  *
-
23  * Several configuration examples are provided in the "config" folder of the Mozzi sources. You may want to look at these, first. The general approach is as follows:
-
24  *
-
25  * @code
-
26  * #include <MozziConfigValues.h> // include this first, for named option values
-
27  * #define MOZZI_AUDIO_CHANNELS MOZZI_STEREO // set to stereo mode
-
28  *
-
29  * #include <Mozzi.h> // *after* all configuration options, include the main Mozzi headers
-
30  * @endcode
-
31  *
-
32  * Alternatively, if a suitable configuration example exists, use:
-
33  * @code
-
34  * #include <config/config_example_avr_stereo.h> // again, do this, before including the main headers
-
35  * @endcode
-
36  *
-
37  * @note
-
38  * Should you include Mozzi headers in more than one compilation unit (i.e. more than one .cpp file) inside the same sketch, you *must* use identical
-
39  * configuration options at the top of each file!

-
46  *
-
47  * Mozzi generally tries to keep your old sketches working, but we continue to find new (and hopefully better) approaches to old problems.
-
48  * Sometimes, keeping API compatibilty with the pre-existing solution may come with a smaller or larger penalty in terms of performance or code size.
-
49  * Therefore - if your sketch supports it - you may be able to get some minor benefit from disabling compatibility code.
-
50  *
-
51  * Currently supported values are:
-
52  * - MOZZI_COMPATIBILITY_1_1 - try to support sketches written for Mozzi version 1.1 (or possibly lower); this is the default when including MozziGuts.h
-
53  * - MOZZI_COMPATIBILITY_2_0 - try to support sketches written for Mozzi version 2.0; this is - currently - the default when including Mozzi.h
-
54  * - MOZZI_COMPATIBILITY_LATEST - always live on the bleeding edge
-
55  *
-
56  * @note
-
57  * MOZZI_COMPATIBILITY_V1_1 does not guarantee, that *everything* from Mozzi 1.1 will continue to work, just that we're doing a reasonable effort.

66  * @note
-
67  * Not all options are available on all platforms, and several options require specific wiring or external components to function on top of this!
-
68  * When customizing this, it is highly recommended to start experimenting with a simple and known-to-work sketch (such as a basic sinewave) to verify that your
-
69  * hardware setup is correct. Similarly, if you observe problems running your "real" sketch, it is often a good idea ot test your sketch with the default audio mode,
-
70  * too (by leaving this option, and preferrably all others, unset).
-
71  *
-
72  * Refer to the @ref hardware specific documentation for which modes are supported on your hardware, and further details!
-
73  *
-
74  * Supported values:
-
75  * - MOZZI_OUTPUT_PWM Output using pulse width modulation (PWM) on a GPIO pin. This is the default on most platforms.
-
76  * On the Arduino Uno (more generally ATMEGA328P), this allows for a sample resolution of 488 (almost 9 bits) on pin 9.
-
77  * Usable pins and resolution will be different on other boards.
-
78  * - MOZZI_OUTPUT_2PIN_PWM Output using pulse width modulation on two GPIO pins, where one pin represents the lower bits, and the other the higer bits of the sample.
-
79  * On the Aduino Uno, this allows for 14 bits of resolution on pins 9 (low) and 10 (high). For further information (wiring etc.) see @ref hardware_avr_2pin.
-
80  * - MOZZI_OUTPUT_EXTERNAL_TIMED Output is not controlled by Mozzi itself, but left to the user sketch. This setting allows to completely customize the audio output, e.g.
-
81  * for connecting to external DACs. For more detail, see @ref external_audio
-
82  * - MOZZI_OUTPUT_EXTERNAL_CUSTOM As above, but additionally bypassing Mozzi's sample buffer. For more detail, see @ref external_audio
-
83  * - MOZZI_OUTPUT_PDM_VIA_I2S Output pulse density modulated (PDM) samples via a (hardware) I2S interface (without a DAC connected to it).
-
84  * - MOZZI_OUTPUT_PDM_VIA_SERIAL Output pulse density modulated (PDM) samples via a hardware serial interface.
-
85  * - MOZZI_OUTPUT_I2S_DAC Output samples to a PT8211 (or compatible) DAC connected to a hardware I2S interface.
-
86  * - MOZZI_OUTPUT_INTERNAL_DAC Output to the interal DAC on boards that support one.

-
117  * Increasing the rate allows for better frequency response, but generally all affects achievable sample bitdepth (especially from PWM output).
-
118  * Also, of course, doubling the sample rate also halves the amount of time available to calculate the each sample, so it
-
119  * may only be useful for relatively simple sketches. The increased frequency response can also make

Detailed Description

-

Internal.

-

Do not use function in this namespace in your sketch!

-

This namespace contains various functions that are used by Mozzi, internally, but are not meant to be used in a sketch.

-

The details of these may change without warning. I repeat: Do not use these in your sketch!

MonoOutput Struct Reference

- -

This struct encapsulates one frame of mono audio output. - More...

- -

#include <AudioOutput.h>

-

Detailed Description

-

This struct encapsulates one frame of mono audio output.

-

Internally, it really just boils down to a single int value, but the struct provides useful API an top of that, for the following:

-

a) To construct an output frame, you should use one of the from8Bit(), fromNBit(), etc. functions. Given a raw input value, at a known resolution (number of bits), this scales the output efficiently to whatever is needed on the target platform. Using this, your updateAudio() function will be portable across different CPU and different output methods, including external DACs. b) The struct provides some convenience API on top of this. Right now, this is the function clip(), replacing the more verbose, and non-portable constrain(x, -244, 243) found in some old sketches. c) The struct provides accessors l() and r() that are source-compatible with StereoOutput, making it easy to e.g. implement support for an external DAC in both mono and stereo. d) Finally, an automatic conversion operator to int aka AudioOutput_t provides backward compatibility with old Mozzi sketches. Internally, the compiler will actually do away with this whole struct, leaving just the same basic fast integer operations as in older Mozzi sketches. However, now, you don't have to rewrite those for different configurations.

Clip frame to supported range.

-

This is useful when at times, but only rarely, the signal may exceed the usual range. Using this function does not avoid artifacts, entirely, but gives much better results than an overflow.

static MonoOutput MonoOutput::from8Bit (int16_t l)
- 		-inlinestatic
-
- -

Construct an audio frame from a zero-centered value known to be in the 8 bit range.

-

On AVR, if MOZZI_OUTPUT_PWM mode, this is effectively the same as calling the constructor, directly (no scaling gets applied). On platforms/configs using more bits, an appropriate left-shift will be performed.

static MonoOutput MonoOutput::fromAlmostNBit (A bits,

)
- 		-inlinestatic
-
- -

Construct an audio frame a zero-centered value known to be above at almost but not quite the N bit range, e.g.

-

at N=8 bits and a litte. On most platforms, this is exactly the same as fromNBit(), shifting up or down to the platforms' available resolution.

-

However, on AVR, MOZZI_OUTPUT_PWM mode (where about 8.5 bits are usable), the value will be shifted to the (almost) 9 bit range, instead of to the 8 bit range. allowing to make use of that extra half bit of resolution. In many cases it is useful to follow up this call with clip(). E.g.:

-
return MonoOutput::fromAlmostNBit(10, oscilA.next() + oscilB.next() + oscilC.next()).clip();

-
- -

Construct an audio frame a zero-centered value known to be in the N bit range.

-

Appropriate left- or right-shifting will be performed, based on the number of output bits available. While this function takes care of the shifting, beware of potential overflow issues, if your intermediary results exceed the 16 bit range. Use proper casts to int32_t or larger in that case (and the compiler will automatically pick the 32 bit overload in this case)

Detailed Description

-

This struct encapsulates one frame of mono audio output.

-

Internally, it really just boils down to two int values, but the struct provides useful API an top of that. For more detail see MonoOutput .

Conversion to int operator: If used in a mono config, returns only the left channel (and gives a compile time warning).

-

This could be turned into an operator for implicit conversion in this case. For now we chose to apply conversion on demand, only, as most of the time using StereoOutput in a mono config, is not intended.

Mozzi brings +TESTEST Currently your Arduino can only beep like a microwave oven. Mozzi brings your Arduino to life by allowing it to produce much more complex and interesting growls, sweeps and chorusing atmospherics. These sounds can be quickly and easily constructed from familiar synthesis units like oscillators, delays, filters and envelopes. You can use Mozzi to generate algorithmic music for an installation or
