我正在開發一個簡單的Beatbox應用程序。首先我用純Java編寫了所有東西，然後我找到了一個很棒的tarsosdsp框架。但是現在我遇到了一個我無法解決的問題。你可以幫我嗎？嘗試填充audioBuffer時使用tarsosdsp audioEvent-Buffer加擾的噪音
我正在設置一個SilenceDetector - 這非常棒。然後我想用過程方法中的audioEvent的數據填充一個byte []緩衝區。在那裏我失敗了......變量audioBuffer的類型是ByteArrayOutputStream，並在運行時重用。請參閱相關代碼片段：
private void setNewMixer(Mixer mixer) throws LineUnavailableException,
UnsupportedAudioFileException {
if(dispatcher!= null){
dispatcher.stop();
}
currentMixer = mixer;
//final AudioFormat format = new AudioFormat(sampleRate, frameRate, channel, true, true);
final DataLine.Info dataLineInfo = new DataLine.Info(TargetDataLine.class, audioFormat);
final TargetDataLine line;
line = (TargetDataLine) mixer.getLine(dataLineInfo);
final int numberOfSamples = bufferSize;
line.open(audioFormat, numberOfSamples);
line.start();
final AudioInputStream stream = new AudioInputStream(line);
JVMAudioInputStream audioStream = new JVMAudioInputStream(stream);
// create a new dispatcher
dispatcher = new AudioDispatcher(audioStream, bufferSize, overlap);
// add a processor, handle percussion event.
silenceDetector = new SilenceDetector(threshold,false);
dispatcher.addAudioProcessor(bufferFiller);
dispatcher.addAudioProcessor(silenceDetector);
dispatcher.addAudioProcessor(this);
// run the dispatcher (on a new thread).
new Thread(dispatcher,"GunNoiseDetector Thread").start();
}
final AudioProcessor bufferFiller = new AudioProcessor() {
@Override
public boolean process(AudioEvent audioEvent) {
if(isAdjusting){
byte[] bb = audioEvent.getByteBuffer().clone();
try {
audioBuffer.write(bb);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("current buffer.size():: "+audioBuffer.size());
}
else {
if (audioBuffer.size() > 0) {
try {
byte[] ba = audioBuffer.toByteArray();
samples.add(ba);
System.out.println("stored: "+ba.length);
audioBuffer.flush();
audioBuffer.close();
audioBuffer = new ByteArrayOutputStream();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return true;
}
@Override
public void processingFinished() {
// TODO Auto-generated method stub
}
};
@Override
public boolean process(AudioEvent audioEvent) {
if(silenceDetector.currentSPL() > threshold){
isAdjusting = true;
lastAction = System.currentTimeMillis();
}
else {
isAdjusting = false;
}
return true;
}
有什麼建議嗎？
