Field

int	PLAYSTATE_STOPPED indicates AudioTrack state is stopped
int	PLAYSTATE_PAUSED indicates AudioTrack state is paused
int	PLAYSTATE_PLAYING indicates AudioTrack state is playing
int	MODE_STATIC Creation mode where audio data is transferred from Java to the native layer only once before the audio starts playing.
int	MODE_STREAM Creation mode where audio data is streamed from Java to the native layer as the audio is playing.
int	STATE_UNINITIALIZED State of an AudioTrack that was not successfully initialized upon creation.
int	STATE_INITIALIZED State of an AudioTrack that is ready to be used.

Constructor

	AudioTrack(int streamType, int sampleRateInHz, int channelConfig, int audioFormat, int bufferSizeInBytes, int mode) Class constructor.
	AudioTrack(AudioAttributes attributes, AudioFormat format, int bufferSizeInBytes, int mode, int sessionId, boolean offload)

Method

int	getMinBufferSize(int sampleRateInHz, int channelConfig, int audioFormat) Returns the estimated minimum buffer size required for an AudioTrack object to be created in the #MODE_STREAM mode.
int	getNativeOutputSampleRate(int streamType) Returns the output sample rate in Hz for the specified stream type.
int	getPlaybackHeadPosition() Returns the playback head position expressed in frames.
int	getState() Returns the state of the AudioTrack instance.
void	play() Starts playing an AudioTrack.
void	release() Releases the native AudioTrack resources.
void	stop() Stops playing the audio data.
int	write(@NonNull byte[] audioData, int offsetInBytes, int sizeInBytes) Writes the audio data to the audio sink for playback (streaming mode), or copies audio data for later playback (static buffer mode).
int	write(@NonNull short[] audioData, int offsetInShorts, int sizeInShorts) Writes the audio data to the audio sink for playback (streaming mode), or copies audio data for later playback (static buffer mode).
int	write(@NonNull ByteBuffer audioData, int sizeInBytes, @WriteMode int writeMode) Writes the audio data to the audio sink for playback (streaming mode), or copies audio data for later playback (static buffer mode).
