How To Play Audio Clips in Java Applications

victor | 24 January, 2007 16:03

It is well-know about the ease to play audio clips in Java when dealing with applets.

It is, however, hard to get a Java application to play audio clips because there is no such interface for audio clips.

In this article, I will demonstrate how to play audio clips.
To play clips, we must use some undocumented classes in Java.

import sun.audio.*; //import the sun.audio package
import java.io.*;
// Open an input stream to the audio file.
InputStream in = new FileInputStream(Filename);
// Create an AudioStream object from the input stream.
AudioStream as = new AudioStream(in);
// Use the static class member "player" from class AudioPlayer to play
// clip.
AudioPlayer.player.start(as);
// Similarly, to stop the audio.
AudioPlayer.player.stop(as);

To use a URL as the audio stream source, substitute the following for the input stream and audio stream setup:

AudioStream as = new AudioStream (url.openStream());

Playing the audio stream continuously adds a bit more complexity:
// Create audio stream as discussed previously.
// Create AudioData source.
AudioData data = as.getData();
// Create ContinuousAudioDataStream.
ContinuousAudioDataStream cas = new ContinuousAudioDataStream (data);
// Play audio.
AudioPlayer.player.play (cas);
// Similarly, to stop the audio.
AudioPlayer.player.stop (cas);
