AudioSource
class AudioSource
| kotlin.Any | |
| ↳ | android.media.MediaRecorder.AudioSource |
Defines the audio source. An audio source defines both a default physical source of audio signal, and a recording configuration. These constants are for instance used in MediaRecorder#setAudioSource(int) or AudioRecord.Builder#setAudioSource(int).

Constants
CAMCORDER
static val CAMCORDER: Int
Microphone audio source tuned for video recording, with the same orientation as the camera if available.
Value: 5
REMOTE_SUBMIX
static val REMOTE_SUBMIX: Int
Audio source for a submix of audio streams to be presented remotely.
An application can use this audio source to capture a mix of audio streams that should be transmitted to a remote receiver such as a Wifi display. While recording is active, these audio streams are redirected to the remote submix instead of being played on the device speaker or headset.
Certain streams are excluded from the remote submix, including AudioManager#STREAM_RING, AudioManager#STREAM_ALARM, and AudioManager#STREAM_NOTIFICATION. These streams will continue to be presented locally as usual.
Capturing the remote submix audio requires the android.Manifest.permission#CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.
Requires
android.Manifest.permission#CAPTURE_AUDIO_OUTPUT
Value: 8
UNPROCESSED
static val UNPROCESSED: Int
Microphone audio source tuned for unprocessed (raw) sound if available, behaves like DEFAULT otherwise.
Value: 9
VOICE_CALL
static val VOICE_CALL: Int
Voice call uplink + downlink audio source
Capturing from VOICE_CALL source requires the android.Manifest.permission#CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.
Value: 4
VOICE_COMMUNICATION
static val VOICE_COMMUNICATION: Int
Microphone audio source tuned for voice communications such as VoIP. It will for instance take advantage of echo cancellation or automatic gain control if available.
Value: 7
VOICE_DOWNLINK
static val VOICE_DOWNLINK: Int
Voice call downlink (Rx) audio source.
Capturing from VOICE_DOWNLINK source requires the android.Manifest.permission#CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.
Value: 3
VOICE_PERFORMANCE
static val VOICE_PERFORMANCE: Int
Source for capturing audio meant to be processed in real time and played back for live performance (e.g karaoke).
The capture path will minimize latency and coupling with playback path.
Value: 10
VOICE_RECOGNITION
static val VOICE_RECOGNITION: Int
Microphone audio source tuned for voice recognition.
Value: 6
VOICE_UPLINK
static val VOICE_UPLINK: Int
Voice call uplink (Tx) audio source.
Capturing from VOICE_UPLINK source requires the android.Manifest.permission#CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.
Value: 2
