public class AudioPlayer
extends Sink
implements javax.media.ControllerListener

This actor accepts an ObjectToken that contains a DataSource. This is typically obtained from the output of the StreamLoader actor. This actor will play Datasources containing a MP3, MIDI, and CD Audio file. After the model is run, a window will pop up allowing control of playing, rate of playback, and volume control.

            throws IllegalActionException,
                   NameDuplicationException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.
