I admit that I am not that familiar with Audition so I apologize for my level of knowledge in advance.
I recorded a video of a speaker in a small room using a nice Panasonic HD camcorder that has a surround mic arrangement built-in. During the talk the speaker was directly across from the camera but major mowing noise was happening outside with the windows open. I exported the audio to Audition from Premiere and I see 6 tracks marked L-R-C-LFE-Ls-Rs. Before diving into noise reduction I thought I would try to toggle channels (i.e. maybe just center for example).
Even though I see waveforms displayed on all six channels only L and R seem to contribute to the sound on the speakers when I play with the toggle buttons on the right side. The other channels have non-zero displays but toggling them on and off has no effect on the audible sound.
Am I missing some additional mixer somewhere? Are these other channels just an illusion?
