I don't know what you want or want to do with it... but with the sound blaster live! it comes with a little program that you can do stuff like chimpmonk, turn it into a woman/man, etc. etc. etc.
i like this small and simple prog called Audacity, works good, not for the whole chipmunk thing, take a look, its got alot of features for such a small prog.http://audacity.sourceforge.net/
