My question *should* be simple to answer, but I’m finding little online to aid me. I have a QuickTime Pro 7 license and actively use GarageBand, however, I’m stumped for what should be one very simple task:
What I have is a recently recorded QuickTime file in which the audio track consists of me speaking in the left channel and me *plus* a second audio track mixed into the right which is significantly delayed. Stated most succinctly, I want to mute / drop the L channel and *only* retain the R channel, converting the result to an AIFF, MP3, or MOV which has a strictly monophonic track. It’s a major no-no to sum L+R into mono because of the delay factor. How to I drop L?
…on Macs this appears to be tremendously difficult. I’m running OS X Mountain Lion 10.8.2, GarageBand 6.0.5, and QuickTime Player 7.6.6 w/pro licensing.
Any tips? ALL links that I’ve followed suggest the L+R -> mono approach which won’t work because of the aforementioned delay issue.
