Default instance.

Public methods

getBufferSizeInBytes

abstract int getBufferSizeInBytes(
    int minBufferSizeInBytes,
    @C.Encoding int encoding,
    @DefaultAudioSink.OutputMode int outputMode,
    int pcmFrameSize,
    int sampleRate,
    int bitrate,
    double maxAudioTrackPlaybackSpeed
)

Returns the buffer size to use when creating an AudioTrack for a specific format and output mode.

Parameters
int minBufferSizeInBytes

The minimum buffer size in bytes required to play this format. See getMinBufferSize.
@C.Encoding int encoding

The C.Encoding of the format.
@DefaultAudioSink.OutputMode int outputMode

How the audio will be played. One of the output modes.
int pcmFrameSize

The size of the PCM frames if the encoding is PCM, 1 otherwise, in bytes.
int sampleRate

The sample rate of the format, in Hz.
int bitrate

The bitrate of the audio stream if the stream is compressed, or NO_VALUE if encoding is PCM or the bitrate is not known.
double maxAudioTrackPlaybackSpeed

The maximum speed the content will be played using setPlaybackParams. 0.5 is 2x slow motion, 1 is real time, 2 is 2x fast forward, etc. This will be 1 unless setEnableAudioTrackPlaybackParams is enabled.
Returns
int

The computed buffer size in bytes. It should always be >= minBufferSizeInBytes. The computed buffer size must contain an integer number of frames: bufferSizeInBytes % pcmFrameSize == 0.
