It's two track mono - the two channels are identical. I grabbed just one track, and in Cool Edit Pro inverted one of the channels, pasted it on top of the other channel, and it came out a flat line.
Thanks for the tip.I figured out the issue. The tracks actually had all the info from both channels on them. I had made a new Montage in Wavelab, since my old template went away with my old operating system. It was sending both channel 1 and 2 to the LF and RF, so they were double mono tracks with all the information from both channels.
I redid one of the shows, and the file size problem is all fixed, and they sure sound better. Live and learn.
I guess the question now is how did TLH know the channels are identical? there is still 2 channels?
