java.lang.Objectcom.frinika.audio.toot.SynchronizedAudioProcess
public abstract class SynchronizedAudioProcess
An audioprocess that can be synchronized from an outside timing source. Useful for e.g. audio playback to be synchronized with a sequencer.

SynchronizedAudioProcess(uk.org.toot.audio.server.AudioServer audioServer,
long initialFramePos)
Construct a new Synchronized audioProcess. |
Method Summary | |
---|---|
protected long |
getFramePos()
Call this method from fillBufferSynchronized to get the framePos according to the external timing source |
protected int |
getMissedFrames()
Call this method from fillBufferSynchronized to get the number of missing frames (glitch) after an external sync notification NOTE: Your tolerance on missed frames should not be too low - since timing functions like System.currentTimeMillis might slide up to 50 ms on some systems. |
int |
getMissedFramesToleranceMillis()
Number of milliseconds of glitch before synchronization if enforced |
int |
processAudio(uk.org.toot.audio.core.AudioBuffer buffer)

abstract void |
processAudioSynchronized(uk.org.toot.audio.core.AudioBuffer buffer)
|
void |
setFramePos(long framePos)
The external timing source should regularly notify with the current frame position here |
void |
setMissedFramesToleranceMillis(int missedFramesToleranceMillis)
Set number of milliseconds of glitch before synchronization if enforced |
