public class Audio
extends Object

Adds audio to GWT applications. Before calling any of the methods to play a sound-bite, make sure that the static method - setRoot() has been called. This is a singleton class and instance of this class can be obtained by calling the getInstance() method.

Limitations:

• Works only with IE and Firefox browsers on Windows only :-(.
