Trouble playing wav in Java
I'm trying to play a
PCM_UNSIGNED 11025.0 Hz, 8 bit, mono, 1 bytes/frame
file as described here (1) and here(2).
The first approach works, but I don't want to depend on sun.*
stuff. The second results in just some leading frames being played, that sounds more like a click. Can't be an IO issue as I'm playing from a ByteArrayInputStream.
Plz share your ideas on why might this happen. TIA.
Solution 1:
I'm not sure why the second approach you linked to starts another thread; I believe the audio will be played in its own thread anyway. Is the problem that your application finishes before the clip has finished playing?
import javax.sound.sampled.*;
import java.io.File;
import java.io.IOException;
import javax.sound.sampled.LineEvent.Type;
private static void playClip(File clipFile) throws IOException,
UnsupportedAudioFileException, LineUnavailableException, InterruptedException {
class AudioListener implements LineListener {
private boolean done = false;
@Override public synchronized void update(LineEvent event) {
Type eventType = event.getType();
if (eventType == Type.STOP || eventType == Type.CLOSE) {
done = true;
notifyAll();
}
}
public synchronized void waitUntilDone() throws InterruptedException {
while (!done) { wait(); }
}
}
AudioListener listener = new AudioListener();
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(clipFile);
try {
Clip clip = AudioSystem.getClip();
clip.addLineListener(listener);
clip.open(audioInputStream);
try {
clip.start();
listener.waitUntilDone();
} finally {
clip.close();
}
} finally {
audioInputStream.close();
}
}
