What I would like to do is extract the audio so I can master it with Ozone, then add the new audio file back in the video, what software would I need to do that?
Preferably free but I don't mind spending some money if I need to.


This can be done by BIAB for the last several years. Open <mp4> file and then select <Video> from the view toolbar. It will decompress the mp4 audio to a WAV file. After editing, it will re-sync the audio and video.
