Constants
CAMCORDER
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
public static final int DEFAULT
Default audio source *
Constant Value: 0 (0x00000000)
MIC
public static final int MIC
Microphone audio source
Constant Value: 1 (0x00000001)
REMOTE_SUBMIX
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
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
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
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
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
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).

VOICE_RECOGNITION
public static final int VOICE_RECOGNITION
Microphone audio source tuned for voice recognition.
Constant Value: 6 (0x00000006)
VOICE_UPLINK
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)
