Many sources are available:
- `output` (default): forwards the whole audio output, and disables playback on the device (mapped to [`REMOTE_SUBMIX`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#REMOTE_SUBMIX)).
- `playback`: captures the audio playback (Android apps can opt-out, so the whole output is not necessarily captured).
- `mic`: captures the microphone (mapped to [`MIC`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#MIC)).
- `mic-unprocessed`: captures the microphone unprocessed (raw) sound (mapped to [`UNPROCESSED`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#UNPROCESSED)).
- `mic-camcorder`: captures the microphone tuned for video recording, with the same orientation as the camera if available (mapped to [`CAMCORDER`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#CAMCORDER)).
- `mic-voice-recognition`: captures the microphone tuned for voice recognition (mapped to [`VOICE_RECOGNITION`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#VOICE_RECOGNITION)).
- `mic-voice-communication`: captures the microphone tuned for voice communications (it will for instance take advantage of echo cancellation or automatic gain control if available) (mapped to [`VOICE_COMMUNICATION`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#VOICE_COMMUNICATION)).
- `voice-call`: captures voice call (mapped to [`VOICE_CALL`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#VOICE_CALL)).
- `voice-call-uplink`: captures voice call uplink only (mapped to [`VOICE_UPLINK`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#VOICE_UPLINK)).
- `voice-call-downlink`: captures voice call downlink only (mapped to [`VOICE_DOWNLINK`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#VOICE_DOWNLINK)).
- `voice-performance`: captures audio meant to be processed for live performance (karaoke), includes both the microphone and the device playback (mapped to [`VOICE_PERFORMANCE`](https://developer.android.com/reference/android/media/MediaRecorder.AudioSource#VOICE_PERFORMANCE)).
### Duplication
An alternative device audio capture method is also available (only for Android
