Play a sound many times in a short time

Question

Hi,
i am using JMF 2.1.1e, and i wondered if there was some trick to play a sound many times in a short time.
The first method i used was:
     private static Thread t     = null;
     private static URL url;
     private static Player player;
     public static void playSound(String name)
          File mp3 = new File("./sounds/level5/"+name+".mp3");
          try { url = mp3.toURL(); } catch (MalformedURLException e) {e.printStackTrace();}
          // to prevent from multiple sounds playing at the same time
          if(t != null && !t.isInterrupted()) t.interrupt();
          t = new Thread()
               public void run()
                    try
                         MediaLocator ml = new MediaLocator(url);
                         player = Manager.createPlayer(ml);
                         player.addControllerListener(
                                   new ControllerListener()
                                        public void controllerUpdate(ControllerEvent event)
                                             if (event instanceof EndOfMediaEvent)
                                                  player.stop();
                                                  player.close();
                         player.realize();
                         player.start();
                    catch (Exception e) { System.out.println("Exception encountered!");}     
          t.start();
I wasn't really satisfied with such a method, since it often took two or three seconds before the sound start playing (maybe because my pc is slow, and the method takes too much memory) so i came up with another idea : storing the sound , calling the "start" method each time i need them, and re-preparing them for the next call short after the call to start; it gives :
static Player[] sounds = new Player[15];
// first initialization of a sound
sounds[0] = new Splay().generate("fac");
// call to the sound, the sound plays nearly immediately
sounds[0].start();
// reinitialization of the sounds, in order to prepare him for the next call
Splay.scheduleInit(0,"fac");
// methods used:
public static void scheduleInit(final int index, final String name) {
new java.util.Timer ().schedule (new TimerTask () { public void run () {
     Screen.sounds[index] = new Splay().generate(name);
}},500);
// and
     public Player generate(String name) {
          Player p = null;
          File mp3 = new File("./sounds/level5/"+name+".mp3");
          try { url = mp3.toURL(); } catch (MalformedURLException e) {e.printStackTrace();}
          try {
               MediaLocator ml = new MediaLocator(url);
               p = Manager.createPlayer(ml);
               p.realize();
          } catch (Exception e) { System.out.println("Exception !");}     
          return p;
it works better than the first one, but it's still not perfect ;
To resume, i need a code that easily allow to :
- Launch tracks fast
- Don't play many sounds in the same time (means that stops the currently played track before loading the new one)
- A player that handle MP3 would be really better compared to a wav player
Will be great if you have something like that
Thank you very much ^^

You can follow the below steps to easily play a sound at runtime - like on mouseover.
1. Make sure your audio is imported in library and has a linkage name specified.
2. Open Windows Menu -> Code Snippets panel and expand HTML5 Canvas -> Event Handlers section.
3. Select your button on Stage and apply the MouseOver Event from Code Snippets to it.
4. In the MouseOverHandler function add the below line and test movie:
          playSound('audio_linkage_name');
If you still face problems let me know.
Also, you might want to go through the SoundJS documentation for more control with Audio in HTML5.
