Separating Audio Layers From .AVI File

[PhoenixOrion602]

I have tons of Star Trek .AVI files on my computer, ripped from DVD. Through an error, upon opening one of them in VLC Media Player, I only heard the sounds of the computer consoles and other sound effects. I know that the effects and the computer's voice are added in post-production, and have suspected for a long time that they are in a separate layer. I would like to know how to separate this layer, so that the voices of the cast and the background music are not playing, making extraction of the sounds very easy and unaltered by the constant music that is playing. Anyone know how to do this?

Open your AC3 audio in a audio editor. Audacity is free and if you install the ffmpeg source plugin you can get at the AC3 track right from the VOB files (you'll get six channels of audio from an 5.1 AC3 audio track).

But you're not likely to find the sound effects are completely separate from the music and other background sounds.

Go to the Audio tab in VLC and check out the audio settings
