"To extract the audio from an MP4 video file you can use "WinFF".
To recombine the processed audio with the video you could use "Avidemux GTK". "
Thanks for the suggestions!
Nice that both are platform independent!
Was able to find a Wiki for "Avidemux GTK" with info for both input and output formats.http://www.avidemux.org/admWiki/doku.ph ... ut_formatshttp://www.avidemux.org/admWiki/doku.ph ... ut_formats
To date have searched to forum for tips, tutorials, or docs on using Audacity to CleanUp any type of Video but only thing I have found is this posting.
Either I am doing something wrong or there is no interested in using Audacity to CleanUp Videos?
Thanks again for your help!
