That is similar to how I repaired my videos, except I used AVIDemux instead of ffmpeg to pull the audio out and put it back in. Other than that, that was pretty much the exact process I used. On one box I did the Split Track and delete bad method, and on the other I did the Stereo to Mono option, because I could not find the first option on that system's version of Audacity. I'm sure it's there somewhere, but I got tired of looking for it. (ProTip to any lurking devs. Stop Changing the ****** interface around for no apparent reason please. If it's broke, don't try to fix it.) :p -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
