N00b here, so pleas bear with me. We had a mixup in either our sound board or our camera and recorded some video only in the left channel. I thought I could just duplicate the traci in garage band, then swap the channel on the duplicate track so we could get audio from both sides. I've duplicated the track, but can't seem to figure out how to swap the audio over to the right side. Can anyone give me any pointers? Thanks in advance for any help.
