public class SoundPlayer
extends javax.swing.JComponent

This class is a Swing component that can load and play a sound clip, displaying progress and controls. The main( ) method is a test program. This component can play sampled audio or MIDI files, but handles them differently. For sampled audio, time is reported in microseconds, tracked in milliseconds and displayed in seconds and tenths of seconds. For midi files time is reported, tracked, and displayed in MIDI "ticks". This program does no transcoding, so it can only play sound files that use the PCM encoding.

The first and only parameter for the main method is the name of the file that provides the audio or midi sample.

This is taken from Section 17.4 of the Third Edition of Java Examples in a Nutshell, "Playing sounds with javax.sound".
