The ABB also offers support for playing sampled audio files, although the specification
does not require support for this feature. To play sampled audio, you just need to get a Player
for the data you wish to hear, and then start the Player running. You can get a Player by asking
Manager for one. In its simplest form, playing sampled audio data looks like this:
URL url = "http://65.215.221.148:8080/wj2/res/relax.wav";
Player p = Manager.createPlayer(url);
p.start();
