Constructor Detail

SilenceSkippingAudioProcessor

public SilenceSkippingAudioProcessor()

Deprecated.

Creates a new silence skipping audio processor.

SilenceSkippingAudioProcessor

public SilenceSkippingAudioProcessor(long minimumSilenceDurationUs,
                                     long paddingSilenceUs,
                                     short silenceThresholdLevel)

Deprecated.

Creates a new silence skipping audio processor. Parameters:minimumSilenceDurationUs - The minimum duration of audio that must be below silenceThresholdLevel to classify that part of audio as silent, in microseconds.paddingSilenceUs - The duration of silence by which to extend non-silent sections, in microseconds. The value must not exceed minimumSilenceDurationUs.silenceThresholdLevel - The absolute level below which an individual PCM sample is classified as silent.

Method Detail

setEnabled

public void setEnabled(boolean enabled)

Deprecated.

Sets whether to skip silence in the input. This method may only be called after draining data through the processor. The value returned by isActive() may change, and the processor must be flushed before queueing more data. Parameters:enabled - Whether to skip silence in the input.

getSkippedFrames

public long getSkippedFrames()

Deprecated.

Returns the total number of frames of input audio that were skipped due to being classified as silence since the last call to BaseAudioProcessor.flush().

Description copied from class: BaseAudioProcessor

isActive

public boolean isActive()

Deprecated.

Description copied from interface: AudioProcessor

Returns whether the processor is configured and will process input buffers. Specified by:isActive in interface AudioProcessorOverrides:isActive in class BaseAudioProcessor

queueInput

public void queueInput([ByteBuffer](https://developer.android.com/reference/java/nio/ByteBuffer.html "class or interface in java.nio")inputBuffer)

Deprecated.

Description copied from interface: AudioProcessor

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

onQueueEndOfStream

protected void onQueueEndOfStream()

Deprecated.

Description copied from class: BaseAudioProcessor

Called when the end-of-stream is queued to the processor. Overrides:onQueueEndOfStream in class BaseAudioProcessor

onFlush

protected void onFlush()

Deprecated.

Description copied from class: BaseAudioProcessor

Called when the processor is flushed, directly or as part of resetting. Overrides:onFlush in class BaseAudioProcessor

onReset

protected void onReset()

Deprecated.

Description copied from class: BaseAudioProcessor

Called when the processor is reset. Overrides:onReset in class BaseAudioProcessor
