The AudioClip class handles both midi and wav files.

Don't forget about midi.
javax.sound.midi.*

Are these sound buffers like DSound?
As in there is only one read/write pointer and thus the same buffer can only be played once until the pointer reaches the end. Which means you have to create multiple versions of the same buffer to allow simultaneous plays of the same sound.
