Audio Stream Direction of Arrival (DOA)

This repository is designed to stream raw audio data, Voice Activity Detection (VAD) status, and decibel (dB) volume levels from 2 microphones on ESP32S3 to a TCP socket.

Prerequisites

• ESP-IDF version 5.0.0

Configuration

Set CONFIG_STA_WIFI_SSID, CONFIG_STA_WIFI_PASS, and CONFIG_TCP_SERVER_IP in sdkconfig.defaults to connect the device to your network and define the TCP server's IP address.

File Descriptions

main.c

• Sends VAD and dB volume data for both microphones to port 5000.
• Streams mic_left data to port 5000.
• Streams mic_right data to port 5001.

main_vad_vol.c

• Streams only VAD and dB volume data to port 5000.

tcp_server_mult.py

• Located on the PC side.
• Sets up TCP sockets to receive the audio, VAD, and volume data.
• Records the audio data into files.
• Outputs volume and VAD data to the console.

tcp_server.py

• Located on the PC side.
• Sets up a TCP socket to receive and print incoming VAD and volume data.
