DefaultAudioSink.DefaultAudioProcessorChain
public class DefaultAudioSink.DefaultAudioProcessorChain implements DefaultAudioSink.AudioProcessorChain
The default audio processor chain, which applies a (possibly empty) chain of user-defined audio processors followed by SilenceSkippingAudioProcessor and SonicAudioProcessor.

Public constructors
DefaultAudioProcessorChain
public DefaultAudioProcessorChain(AudioProcessor[] audioProcessors)
Creates a new default chain of audio processors, with the user-defined
audioProcessors applied before silence skipping and speed adjustment processors.
DefaultAudioProcessorChain
public DefaultAudioProcessorChain(
AudioProcessor[] audioProcessors,
SilenceSkippingAudioProcessor silenceSkippingAudioProcessor,
SonicAudioProcessor sonicAudioProcessor
)
Creates a new default chain of audio processors, with the user-defined
audioProcessors applied before silence skipping and speed adjustment processors.
Public methods
applyPlaybackParameters
public PlaybackParameters applyPlaybackParameters(PlaybackParameters playbackParameters)
Configures audio processors to apply the specified playback parameters immediately, returning the new playback parameters, which may differ from those passed in. Only called when processors have no input pending.
| Parameters | |
|---|---|
PlaybackParameters playbackParameters |
The playback parameters to try to apply. |
| Returns | |
|---|---|
PlaybackParameters |
The playback parameters that were actually applied. |
applySkipSilenceEnabled
public boolean applySkipSilenceEnabled(boolean skipSilenceEnabled)
Configures audio processors to apply whether to skip silences immediately, returning the new value. Only called when processors have no input pending.
| Parameters | |
|---|---|
boolean skipSilenceEnabled |
Whether silences should be skipped in the audio stream. |
| Returns | |
|---|---|
boolean |
The new value. |
getAudioProcessors
public AudioProcessor[] getAudioProcessors()
Returns the fixed chain of audio processors that will process audio. This method is called once during initialization, but audio processors may change state to become active/inactive during playback.
getMediaDuration
public long getMediaDuration(long playoutDuration)
Returns the media duration corresponding to the specified playout duration, taking speed adjustment due to audio processing into account.
The scaling performed by this method will use the actual playback speed achieved by the audio processor chain, on average, since it was last flushed. This may differ very slightly from the target playback speed.
| Parameters | |
|---|---|
long playoutDuration |
The playout duration to scale. |
| Returns | |
|---|---|
long |
The corresponding media duration, in the same units as |
getSkippedOutputFrameCount
public long getSkippedOutputFrameCount()
Returns the number of output audio frames skipped since the audio processors were last flushed.
