I downloaded some music from a site, but it's a Quicktime movie, with just an audio track (in AAC). I tried just extracting the track, but that just creates a new movie with the same audio track. I could export the sound, but then I'd have to re-compress it, and I'd rather avoid that. I also tried exporting the entire movie to MPEG-4, during Pass-through on the audio, but that also gives me a new movie with the same audio track. Does anyone know of a way to extract just the audio and have it be in its own file, rather than a track of a second movie?
