public final class ToInt16PcmAudioProcessor extends BaseAudioProcessor

java.lang.Object
↳	androidx.media3.common.audio.BaseAudioProcessor
	↳	androidx.media3.common.audio.ToInt16PcmAudioProcessor

An AudioProcessor that converts different PCM audio encodings to 16-bit integer PCM. The following encodings are supported as input:

ENCODING_PCM_8BIT
ENCODING_PCM_16BIT (isActive will return false)
ENCODING_PCM_16BIT_BIG_ENDIAN
ENCODING_PCM_24BIT
ENCODING_PCM_24BIT_BIG_ENDIAN
ENCODING_PCM_32BIT
ENCODING_PCM_32BIT_BIG_ENDIAN
ENCODING_PCM_FLOAT

Summary

Public constructors
`ToInt16PcmAudioProcessor()`

Public methods
`AudioProcessor.AudioFormat`	`onConfigure(AudioProcessor.AudioFormat inputAudioFormat)` Called when the processor is configured for a new input format.
`void`	`queueInput(ByteBuffer inputBuffer)` Queues audio data between the position and limit of the `inputBuffer` for processing.

Inherited Constants

From androidx.media3.common.audio.AudioProcessor

static final ByteBuffer

EMPTY_BUFFER

An empty, direct ByteBuffer.

Inherited fields

From androidx.media3.common.audio.BaseAudioProcessor

`AudioProcessor.AudioFormat`	`inputAudioFormat` The current input audio format.
`AudioProcessor.AudioFormat`	`outputAudioFormat` The current output audio format.

Inherited methods

From androidx.media3.common.audio.BaseAudioProcessor

`final AudioProcessor.AudioFormat`	`configure(AudioProcessor.AudioFormat inputAudioFormat)` Configures the processor to process input audio with the specified format.
`final void`	`flush()` Clears any buffered data and pending output.
`ByteBuffer`	`@CallSuper getOutput()` Returns a buffer containing processed output data between its position and limit.
`final boolean`	`hasPendingOutput()` Returns whether the current output buffer has any data remaining.
`boolean`	`isActive()` Returns whether the processor is configured and will process input buffers.
`boolean`	`@CallSuper isEnded()` Returns whether this processor will return no more output from `getOutput` until `flush` has been called and more input has been queued.
`void`	`onFlush()` Called when the processor is flushed, directly or as part of resetting.
`void`	`onQueueEndOfStream()` Called when the end-of-stream is queued to the processor.
`void`	`onReset()` Called when the processor is reset.
`final void`	`queueEndOfStream()` Queues an end of stream signal.
`final ByteBuffer`	`replaceOutputBuffer(int size)` Replaces the current output buffer with a buffer of at least `size` bytes and returns it.
`final void`	`reset()` Resets the processor to its unconfigured state, releasing any resources.

Public constructors

ToInt16PcmAudioProcessor

public ToInt16PcmAudioProcessor()

Public methods

onConfigure

public AudioProcessor.AudioFormat onConfigure(AudioProcessor.AudioFormat inputAudioFormat)

Called when the processor is configured for a new input format.

Throws
`androidx.media3.common.audio.AudioProcessor.UnhandledAudioFormatException`

queueInput

public void queueInput(ByteBuffer inputBuffer)

Queues audio data between the position and limit of the inputBuffer for processing. After calling this method, processed output may be available via getOutput. Calling queueInput(ByteBuffer) again invalidates any pending output.

Parameters
`ByteBuffer inputBuffer`	The input buffer to process. It must be a direct byte buffer with native byte order. Its contents are treated as read-only. Its position will be advanced by the number of bytes consumed (which may be zero). The caller retains ownership of the provided buffer.
