It’s actually quite simple meanwhile thanks to a Foobar plugin available here:

So the big challenge isn’t to decode it but to get one’s hands on those DTS CDs in the first place. 😉
Yeah, that’s the software I used to decode the tracks and convert them to a usable format. I then opened the individual tracks in an audio editing app and I was able to isolate and mix the levels of each track.
It’s really exciting to be able to listen to the original audio that I would have heard when I saw it in theaters back in 1993.
