Cas: I've already tested JOrbis in the past, and I've noticed that it was very very slow... :-/
zainuluk: Yeah, OpenAL is a very used sound technology in game (UT2003, etc...), but there are many others API like Audiere (http://sourceforge.net/projects/audiere
), which is very fast and support MOD, WAV, OGG and optionally MP3, JavaLayer (http://www.javazoom.net/javalayer/javalayer.html
), a MP3 java player (a little bit slow) and many others.
Try a search in google, you will surely find something interesting.
