Ok, this is going out all of you guys, or gals, that are way smarter than I am. I burned a short film to DVD when I was in college, and it is the only format that I have of this one scene. I need to get the scream from the girl (yes a horror short from college). The problem is that I have a Metallica sound blasting over the "great scream".
So what need to do is some how extract the Metallica song out of the clip (I have already imported the DVD into quicktime with MPEG Streamclip) so that all I have left is the original audio from my minidv footage.
Is this possible?
I am interested to know your thoughts. Or is there a better way? Or maybe not as good, but as good as I can get it route?

There might be a way to POSSIBLY get close to what you want. If the DVD audio track is a mono mix (ideally) and you can find a copy of the song, preferably the same source that you used for the original DVD, you might be able to copy it, mix the song to mono and then put it through a mixer or software program that is capable in INVERTING THE PHASE of the clip. If you then add this over the original DVD audio, the music should (in theory) cancel out and leave just the scream.
It's a long shot and would involve all of the planets lining up just right, not to mention the music track, but it is possible...in theory.
Might get you close anyhow...

Hi,
off topic:
I am a freelance Sound Designer. I have just found this forum as I wish to learn to edit with FCP.
On topic:
It IS POSSIBLE to reduce the background noise (in this case Metallica)
Using a sophisticated NR would be the way forward. I would suggest using the BNR on Pro-Tools or Waves have a few reasonable one's - The second option would be to filter the frequencies (via a EQ) to reduce unwanted noises. If it hasn't gone completely then you can always mask the sound with other sound FX. By this I mean that you can create alternatives within the scream - after all it is a horror movie.
If you know someone that has Pro Tools or another Pro. sound App then ask them. If not it's going to cost you a little.
