I'm about to buy some music from Music 2 Hues - Royalty Free Music Downloads | Buyout CDs | Production Music Library (http://www.music2hues.com) and the option is either MP3 or WAV format.
Any + or - for either? Seems that I've used both formats, I just don't know if one will deliver better audio after rendering to AC-3 for a DVD. Thanks!

WAV is absolutely better, especially if you're going to compress it down to AC-3. MP3 is already very compressed.

You could *get away* with MP3, but why would you when you have the choice?

Thanks David, just the advice I needed.
