midi, wave, mp3 cross platform?

["Calvin Ellis" <kyndig gmail com>]

Hello list,

I'm looking for a cross platform library to incorporate into my software application. The application currently takes the commands required to play midi, wave, and mp3 files. Is there a cross platform library which I can bundle with my application? The application currently works on Linux, Windows, and MAC OS X ( with X11 install - can't wait for the native MAC completion! )

Thank you,
Calvin
