OGG-Audio mit Java abspielen

Wer OGG-Audiodateien in seiner Java-Anwendung abspielen möchte, stößt wahrscheinlich auf größere Schwierigkeiten. Ich biete hier daher eine Klasse an, die das Problem löst. Sie bedingt allerdings die Bibilothek j-ogg, die entsprechend in den Classpath einzubinden ist.

SoundPlayer.java
