The reason I want to do this is so that I can normalize the audio and reduce the noise a little as well before generating proxies in Gearshift. If I do this after I generate the proxies, the sound changes when I shift gears. What I wonder is if I'm gaining an extra rendering generation when I load an M2T file into Soundforge, edit it, then save it?

Do not edit m2t audio (mpeg 1/layer II audio) in Sound Forge or anywhere else. You're editing a highly compressed format. You really, really want to edit the file after it's been processed/converted. In other words, only edit PCM audio, not mpeg audio.

What you say makes perfect sense, but I can't hear or see the difference. I realize that that doesn't mean there isn't damage being done. My hearing just isn't good enough to hear it.

This is why I started another thread about having an option to swap out just the video portion of the file and keep the proxy audio portion for the final render. That way if you wanted to do something like use noise reduction on a clip, you'd be working with the uncompressed audio and using it during the final render. It's a good idea I believe.

In the mean time though, I'm just trying to figure out the best way to work as things are. I know I could render another audio track, but that would be akward as I'm moving the interview sections around, and I wanted to do noise reduction on the unedited track because it works better that way.
