AudioAttributes

ALLOW_CAPTURE_BY_ALL

static val ALLOW_CAPTURE_BY_ALL: Int

Indicates that the audio may be captured by any app. For privacy, the following usages cannot be recorded: VOICE_COMMUNICATION*, USAGE_NOTIFICATION*, USAGE_ASSISTANCE* and USAGE_ASSISTANT. On android.os.Build.VERSION_CODES#Q, this means only USAGE_UNKNOWN, USAGE_MEDIA and USAGE_GAME may be captured. See android.media.projection.MediaProjection and Builder.setAllowedCapturePolicy.

Value: 1

ALLOW_CAPTURE_BY_NONE

static val ALLOW_CAPTURE_BY_NONE: Int

Indicates that the audio is not to be recorded by any app, even if it is a system app. It is encouraged to use ALLOW_CAPTURE_BY_SYSTEM instead of this value as system apps provide significant and useful features for the user (such as live captioning and accessibility). See Builder.setAllowedCapturePolicy.

Value: 3

ALLOW_CAPTURE_BY_SYSTEM

static val ALLOW_CAPTURE_BY_SYSTEM: Int

Indicates that the audio may only be captured by system apps. System apps can capture for many purposes like accessibility, live captions, user guidance... but abide to the following restrictions: - the audio cannot leave the device - the audio cannot be passed to a third party app - the audio cannot be recorded at a higher quality than 16kHz 16bit mono See Builder.setAllowedCapturePolicy.

Value: 2

CONTENT_TYPE_MOVIE

static val CONTENT_TYPE_MOVIE: Int

Content type value to use when the content type is a soundtrack, typically accompanying a movie or TV program.

Value: 3

CONTENT_TYPE_MUSIC

static val CONTENT_TYPE_MUSIC: Int

Content type value to use when the content type is music.

Value: 2

CONTENT_TYPE_SONIFICATION

static val CONTENT_TYPE_SONIFICATION: Int

Content type value to use when the content type is a sound used to accompany a user action, such as a beep or sound effect expressing a key click, or event, such as the type of a sound for a bonus being received in a game. These sounds are mostly synthesized or short Foley sounds.

Value: 4

CONTENT_TYPE_SPEECH

static val CONTENT_TYPE_SPEECH: Int

Content type value to use when the content type is speech.

Value: 1

CONTENT_TYPE_UNKNOWN

static val CONTENT_TYPE_UNKNOWN: Int

Content type value to use when the content type is unknown, or other than the ones defined.

Value: 0

FLAG_AUDIBILITY_ENFORCED

static val FLAG_AUDIBILITY_ENFORCED: Int

Flag defining a behavior where the audibility of the sound will be ensured by the system. To ensure sound audibility, the system only uses built-in speakers or wired headphones and specifically excludes wireless audio devices.

Note this flag should only be used for sounds subject to regulatory behaviors in some countries, such as for camera shutter sound, and not for routing behaviors.

Value: 1

FLAG_HW_AV_SYNC

static val FLAG_HW_AV_SYNC: Int

Flag requesting the use of an output stream supporting hardware A/V synchronization.

Value: 16

FLAG_LOW_LATENCY

static val FLAG_LOW_LATENCY: Int

Deprecated: Use AudioTrack.Builder.setPerformanceMode(int) with AudioTrack.PERFORMANCE_MODE_LOW_LATENCY to control performance.

Flag requesting a low latency path when creating an AudioTrack. When using this flag, the sample rate must match the native sample rate of the device. Effects processing is also unavailable. Note that if this flag is used without specifying a bufferSizeInBytes then the AudioTrack's actual buffer size may be too small. It is recommended that a fairly large buffer should be specified when the AudioTrack is created. Then the actual size can be reduced by calling AudioTrack.setBufferSizeInFrames(int). The buffer size can be optimized by lowering it after each write() call until the audio glitches, which is detected by calling AudioTrack.getUnderrunCount(). Then the buffer size can be increased until there are no glitches. This tuning step should be done while playing silence. This technique provides a compromise between latency and glitch rate.

Value: 256

SPATIALIZATION_BEHAVIOR_AUTO

static val SPATIALIZATION_BEHAVIOR_AUTO: Int

Constant indicating the audio content associated with these attributes will follow the default platform behavior with regards to which content will be spatialized or not.

Value: 0

static val SPATIALIZATION_BEHAVIOR_NEVER: Int

Constant indicating the audio content associated with these attributes should never be virtualized.
