Play a Sound with Java Media Framework Hack #72

Use the Java Media Framework for better performance and support for more

audio formats.

Java Media Framework (JMF) is Sun’s attempt to bring a broadly focused

multimedia framework to Java, supporting audio, video, and other time-

based media types. The idea is to provide Java desktop applications with

these features across operating systems. Like JavaSound, it’s meant to be

extended so that Sun or third parties could add support for new file formats

or codecs (the compression/decompression encoding schemes used inside

those files).

JMF offers another way to provide sound from an application. The advan-

tages of doing so are that JMF may ...
