Hi everyone,
I have a project where I need to extract just the dialogue from a movie, without any of the backing music or sound effects. I managed to rip the 5.1 track off the DVD, unfortunately though, the centre track contains dialogue as well as background music. The left and right tracks however, only contain the background music.
I was wondering if there was a way to mix the centre track and a left or right track and make the background music "cancel out" somehow? Any help would be greatly appreciated.
Thanks.

Probably almost every editor can do this. Personally, I know about Audacity and SoX. The function is often called “invert waveform” or similar, because a 180° phase shift is equivalent to inverting the sign of each sample (e.g., change +0.83 into -0.83).
