Audio Source

Use an Android device as a USB microphone
Audio Source forwards Android microphone audio input to the PulseAudio daemon through ADB, so you can use your Android device as a USB microphone.

Requirements:

* Device with at least Android 4.0 (API level 14), but fully tested only on Android 10 (API level 29) so your mileage may vary.
* GNU/Linux machine with:
* Android SDK Platform Tools (requires adb in PATH).
* PulseAudio or PipeWire with PulseAudio support (requires pactl in PATH).
* Python 3 (requires python3 in PATH).

For further details, see the project's documentation.
