I'm working on a preservation effort for a movie, I'm not done yet so I don't want to name the film. But I've done a fresh telecine of it, and can no longer get access to the film reels. So what I'm wondering, is, using what free/paid tools could I take the mono audio and divide it up into stereo channels. I'm not even sure if this is possible, but if it is, it'd help my project out alot. I can give you information as to which format the audio and video is in, if needed.
Thanks!
