Pro Logic is a matrix, not separately encoded surround.
If you import it and render straight through as stereo PCM, I believe the matrix and phase shift will persist, and be recognized by PL enabled receiver / amps.
Yes and it can be decoded to separate tracks the same as a PLII receiver will. I want to be able to edit and mix the separate tracks. The only ways I know to do it is to either buy surcode or to play it back through a receiver and capture the decoded output.
I'm looking for a lower cost software solution rather than a lash up of hardware everytime I want to separate the tracks.
