Any way to import Planescape Torment sounds sets into the EE engine?

Hey all,

I have a set of the old Planescape:Torment voicesets that were ripped from P:T using BGTeam's Biffworkshop utility. Of course, that only creates files that worked using the BG2-style player (they won't play outside of the old IE engine games). Is there any way to take these files and decompress them into regular .Wav files that we could drop into the enhanced edition games?
