Dolby Prologic question

[-=MadDog=-]

Is it possible to isolate the four channels (left/right/rear/center) of a Dolby Prologic wave-file into separate files?

To separate the left and right channel is no problem, but I also want to separate the rear and center channels (wich actually are encoded in the left/right-signal).

Theoretically, you can.

But, to do that, you would need a software DPL decoder. And, AFAIK, that doesn't exist.
