Kotlin |Java

public final class MediaRecorder.AudioSource
extends Object

java.lang.Object
↳	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).

Summary

Constants
int	CAMCORDER Microphone audio source tuned for video recording, with the same orientation as the camera if available.
int	DEFAULT Default audio source *
int	MIC Microphone audio source
int	REMOTE_SUBMIX Audio source for a submix of audio streams to be presented remotely.
int	UNPROCESSED Microphone audio source tuned for unprocessed (raw) sound if available, behaves like DEFAULT otherwise.
int	VOICE_CALL Voice call uplink + downlink audio source Capturing from VOICE_CALL source requires the Manifest.permission.CAPTURE_AUDIO_OUTPUT permission.
int	VOICE_COMMUNICATION Microphone audio source tuned for voice communications such as VoIP.
int	VOICE_DOWNLINK Voice call downlink (Rx) audio source.
int	VOICE_PERFORMANCE Source for capturing audio meant to be processed in real time and played back for live performance (e.g karaoke).
int	VOICE_RECOGNITION Microphone audio source tuned for voice recognition.
int	VOICE_UPLINK Voice call uplink (Tx) audio source.

Inherited methods

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Constants

CAMCORDER

Added in API level 7

public static final int CAMCORDER

Microphone audio source tuned for video recording, with the same orientation as the camera if available.

Constant Value: 5 (0x00000005)

DEFAULT

Added in API level 1

public static final int DEFAULT

Default audio source *

Constant Value: 0 (0x00000000)

MIC

Added in API level 1

public static final int MIC

Microphone audio source

Constant Value: 1 (0x00000001)

REMOTE_SUBMIX

Added in API level 19

public static final int REMOTE_SUBMIX

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 Manifest.permission.CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.

Requires Manifest.permission.CAPTURE_AUDIO_OUTPUT

Constant Value: 8 (0x00000008)

UNPROCESSED

Added in API level 24

public static final int UNPROCESSED

Microphone audio source tuned for unprocessed (raw) sound if available, behaves like DEFAULT otherwise.

Constant Value: 9 (0x00000009)

VOICE_CALL

Added in API level 4

public static final int VOICE_CALL

Voice call uplink + downlink audio source

Capturing from VOICE_CALL source requires the Manifest.permission.CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.

Constant Value: 4 (0x00000004)

VOICE_COMMUNICATION

Added in API level 11

public static final int VOICE_COMMUNICATION

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.

Constant Value: 7 (0x00000007)

VOICE_DOWNLINK

Added in API level 4

public static final int VOICE_DOWNLINK

Voice call downlink (Rx) audio source.

Capturing from VOICE_DOWNLINK source requires the Manifest.permission.CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.

Constant Value: 3 (0x00000003)

VOICE_PERFORMANCE

Added in API level 29

public static final int VOICE_PERFORMANCE

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.

Constant Value: 10 (0x0000000a)

VOICE_RECOGNITION

Added in API level 7

public static final int VOICE_RECOGNITION

Microphone audio source tuned for voice recognition.

Constant Value: 6 (0x00000006)

VOICE_UPLINK

Added in API level 4

public static final int VOICE_UPLINK

Voice call uplink (Tx) audio source.

Capturing from VOICE_UPLINK source requires the Manifest.permission.CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.

Constant Value: 2 (0x00000002)
