AudioTest.java

The following code is configured to bring up a blank JFrame, which the user can close after the sound clip has played. You may choose to put in a waiting time instead, by changing the main program to

	AudioTest inst = new AudioTest(false);
 	inst.test(filename);
	inst.sleep(3500);

If the wait time is too short the program will exit before the end of the sound clip.

There also seems to be a problem with .au files. Java throws a javax.sound.sampled.LineUnavailableException for format

ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame.

You can use a code converter such as AUD-to-WAV to convert .au files to .wav format.
