当JAV中包含WAV时，如何在Java中播放WAV

Question

I've been trying to deal with sound on my Applet for a bit now, and Instead of trying all the different methods, what is the best way to play Sound in Java? There are a few requirements:

• Needs to be able to loop
• Needs to be able to load a WAV from an archive JAR(I think with the getClass().getResource)
• Needs to be able to play more than one sound at the same time, and not clip already playing sounds

Thanks you so much for looking at my question and I hope you guys have an answer!

Thanks to the wonderful help I almost have it working with this:

public class MyGame() {
   Clip bullet;


    public void init(){
        try {

        bullet = AudioSystem.getClip();
        URL url2 = this.getClass().getResource("bulletSound.wav");
        AudioInputStream ais2 = AudioSystem.getAudioInputStream( url2 );

        bullet.open(ais2);
        } catch (LineUnavailableException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        } catch (UnsupportedAudioFileException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        }
    }
    randomMethodToPlayBullet(){
        bullet.setFramePosition(0);
        bullet.start();
    }
}

The problem is that the bullet sound plays, but if the randomMethodToPlayBullet is called say twice in a row, before the first bullet sound is done, the seonc one doesnt play.

Answer 1

The best way to load resources from jar file is to put in the same folder a class and get the resource with .class.getResource(...) or .class.getResourceaAsStream(...) methods:

URL url = ClazzInTheFolderOfMyMidiFile.class.getResource(nameOfMidiFile);

or

InputStream resourceAsStream = ClazzInTheFolderOfMyMidiFile.class.getResourceAsStream(nameOfMidiFile);

Answer 2

The answer for:

• Small samples is Clip . See the Java Sound info. page for an example of use.
• Large samples is BigClip .

Answer 3

You can't play the same Clip twice at the same time. You have to create another instance of Clip to play the sound twice at the same time.

Note that there will be a limit how many clips you can play, so the clip API may not be suited to support a sound-heavy game.
