Re: Post Production Audio Advice

Dialogue is generally kept centre-panned in a stereo mix. This "phantom centre" is created by playing the sound in-phase at equal levels on both speakers.

You can accomplish the same effect by duplicating a track and panning one track hard-right and the other hard-left. However, you're just doubling the number of tracks you have to work with, needlessly increasing the amount of work you have to do. Moreover, if the two tracks aren't identical (perhaps one gets moved slightly), you could experience all sorts of phase-related problems.

Keep the Dialogue mono, and use effects and music to build a nice stereo image.
