All Implemented Interfaces:

AudioObject, AudioSink, javax.media.ControllerListener, javax.media.datasink.DataSinkListener

public class AudioMediaLineSink

extends DefaultAudioSink

implements javax.media.ControllerListener, javax.media.datasink.DataSinkListener

AudioSink wrapper for a javax.media playback device, enabling audio data to be played to speakers etc (avoiding the bugs encountered by the javax.sound.sampled playback devices when a TargetDataLine is running at the same time). Requires the JMF to be installed.

AudioMediaLineSink(int rate, int bits, int chans, boolean signed, boolean bigEndian)

Method Summary

void	controllerUpdate(javax.media.ControllerEvent evt)
void	dataSinkUpdate(javax.media.datasink.DataSinkEvent evt)
int	write(byte[] data, int offset, int length) Used to write data to this sink - called by the AudioSource which this sink is connected to (if its startSending method is used) so need not be called explicitly by an application.
