How do I play .cda (music from cd''s) with Direct Sound? I would also like to play them from my harddrive instead of directly from the cd. If all this isn''t possible, then how do I play .mp3 files with Direct Sound? This is all because I am making a game and I want to use music from my cd''s but since I only know how to play .wav files, then I have to convert .cda -> .wav and they end up being like 15-20MB!! Way too huge. Any suggestions on how to play the music I want would be very helpful! Thanks!

well to play cd audio tracks you can use MCI commands,
but this does not play the audio with direct sound.

to play mp3s
check out the dx section of http://cust.nol.at/ppee/mainframeeng.htm
or the golgotha source code.
