AudioProfile


open class AudioProfile : Parcelable
kotlin.Any
   ↳ android.media.AudioProfile

An AudioProfile is specific to an audio format and lists supported sampling rates and channel masks for that format. An AudioDeviceInfo has a list of supported AudioProfiles. There can be multiple profiles whose encoding format is the same. This usually happens when an encoding format is only supported when it is encapsulated by some particular encapsulation types. If there are multiple encapsulation types that can carry this encoding format, they will be reported in different audio profiles. The application can choose any of the encapsulation types.

Summary

Constants
static Int

Encapsulation format is defined in standard IEC 61937.

static Int

No encapsulation type is specified.

static Int

Encapsulation format is PCM, which can be used by other formats that can be wrapped in a PCM frame, such as DSD(Direct Stream Digital).

No encapsulation type is specified.

Value: 0

AUDIO_ENCAPSULATION_TYPE_PCM

Public methods

describeContents

Added in API level 33
open fun describeContents(): Int
Return
Int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 31
open fun equals(other: Any?): Boolean
Parameters
obj the reference object with which to compare.
Return
Boolean true if this object is the same as the obj argument; false otherwise.

getChannelIndexMasks

Added in API level 31
open fun getChannelIndexMasks(): IntArray
Return
IntArray an array of channel index masks that are associated with the encoding format. This value cannot be null.

getChannelMasks

Added in API level 31
open fun getChannelMasks(): IntArray
Return
IntArray an array of channel position masks that are associated with the encoding format. This value cannot be null.

getEncapsulationType

Added in API level 31
open fun getEncapsulationType(): Int

The encapsulation type indicates what encapsulation type is required when the framework is using this format when playing to a device exposing this audio profile. When encapsulation is required, only playback with android.media.AudioTrack API is supported. But playback with android.media.MediaPlayer is not. When an encapsulation type is required, the AudioFormat encoding selected when creating the AudioTrack must match the encapsulation type, e.g AudioFormat.ENCODING_IEC61937 for AUDIO_ENCAPSULATION_TYPE_IEC61937.

Return
Int an integer representing the encapsulation type Value is android.media.AudioProfile#AUDIO_ENCAPSULATION_TYPE_NONE, android.media.AudioProfile#AUDIO_ENCAPSULATION_TYPE_IEC61937, or android.media.AudioProfile#AUDIO_ENCAPSULATION_TYPE_PCM

getFormat

Added in API level 31
open fun getFormat(): Int
Return
Int the encoding format for this AudioProfile. Value is android.media.AudioFormat#ENCODING_DEFAULT, android.media.AudioFormat#ENCODING_PCM_16BIT, android.media.AudioFormat#ENCODING_PCM_8BIT, android.media.AudioFormat#ENCODING_PCM_FLOAT, android.media.AudioFormat#ENCODING_AC3, android.media.AudioFormat#ENCODING_E_AC3, android.media.AudioFormat#ENCODING_DTS, android.media.AudioFormat#ENCODING_DTS_HD, android.media.AudioFormat#ENCODING_MP3, android.media.AudioFormat#ENCODING_AAC_LC, android.media.AudioFormat#ENCODING_AAC_HE_V1, android.media.AudioFormat#ENCODING_AAC_HE_V2, android.media.AudioFormat#ENCODING_IEC61937, android.media.AudioFormat#ENCODING_DOLBY_TRUEHD, android.media.AudioFormat#ENCODING_AAC_ELD, android.media.AudioFormat#ENCODING_AAC_XHE, android.media.AudioFormat#ENCODING_AC4, android.media.AudioFormat#ENCODING_E_AC3_JOC, android.media.AudioFormat#ENCODING_DOLBY_MAT, android.media.AudioFormat#ENCODING_OPUS, android.media.AudioFormat#ENCODING_PCM_24BIT_PACKED, android.media.AudioFormat#ENCODING_PCM_32BIT, android.media.AudioFormat#ENCODING_MPEGH_BL_L3, android.media.AudioFormat#ENCODING_MPEGH_BL_L4, android.media.AudioFormat#ENCODING_MPEGH_LC_L3, android.media.AudioFormat#ENCODING_MPEGH_LC_L4, android.media.AudioFormat#ENCODING_DTS_UHD_P1, android.media.AudioFormat#ENCODING_DRA, android.media.AudioFormat#ENCODING_DTS_HD_MA, android.media.AudioFormat#ENCODING_DTS_UHD_P2, or android.media.AudioFormat#ENCODING_DSD
