They are encrypted threw bink. Only way to do it is get an mp3 recorder and record the music as it plays. I used mp3 direct cut to get them.
It's a pain in the ass, but worth it until the OST is released or Kirill (the composer) puts them up on his website at
http://www.kirillpokrovsky.com/ He's got the music from the first two games there for free download.
