we have an instruction video with a bad sound. Most of it caused by breathing into the micro.
I thought about using Audacity to clean it up.
But first I have to "extract" the audio only, and later I have to re-attach the audio afterwards.
I do not have any experience with it so any recommendation is welcome.
ffmpeg is quite useful for extracting audio. ffmpeg -i in.mkv -vn -ab 128 out.mp3
