Bring user audible sounds to harmonic for use with platform status sounds/tones.

[bperseghetti]

Desired behavior

To fully simulate a platform it would be beneficial to allow for user audible tones.
IE: gps lock, back-up, battery critical, platform startup success, mode transitions, etc

Example of a "vehicle's clean startup" sound:

output.mp4

Implementation suggestion

Ideally allow for given frequencies to be played with assigned duration on a topic that will allow for playing sound through either QT front-end or potentially other back-end if running headless.
IE: series of defined frequencies and relative duration
