MediaRecorder.AudioSource

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 setAudioSource(int) or setAudioSource(int).

Summary

Constants
`int`	`CAMCORDER` Microphone audio source with same orientation as camera if available, the main device microphone otherwise
`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 `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_RECOGNITION` Microphone audio source tuned for voice recognition if available, behaves like `DEFAULT` otherwise.
`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 millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Constants

CAMCORDER

Added in API level 7

int CAMCORDER

Microphone audio source with same orientation as camera if available, the main device microphone otherwise

Constant Value: 5 (0x00000005)

DEFAULT

Added in API level 1

int DEFAULT

Default audio source

Constant Value: 0 (0x00000000)

MIC

Added in API level 1

int MIC

Microphone audio source

Constant Value: 1 (0x00000001)

REMOTE_SUBMIX

Added in API level 19

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 STREAM_RING, STREAM_ALARM, and STREAM_NOTIFICATION. These streams will continue to be presented locally as usual.

Capturing the remote submix audio requires the CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.

Constant Value: 8 (0x00000008)

UNPROCESSED

Added in API level 24

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

int VOICE_CALL

Voice call uplink + downlink audio source

Capturing from VOICE_CALL source requires the 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

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. It otherwise behaves like DEFAULT if no voice processing is applied.

Constant Value: 7 (0x00000007)

VOICE_DOWNLINK

Added in API level 4

int VOICE_DOWNLINK

Voice call downlink (Rx) audio source.

Capturing from VOICE_DOWNLINK source requires the 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_RECOGNITION

Added in API level 7

int VOICE_RECOGNITION

Microphone audio source tuned for voice recognition if available, behaves like DEFAULT otherwise.

Constant Value: 6 (0x00000006)

VOICE_UPLINK

Added in API level 4

int VOICE_UPLINK

Voice call uplink (Tx) audio source.

Capturing from VOICE_UPLINK source requires the 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)
