I am interested in making a trailer for ANH, and naturally I would like as much of the dialogue as possible to be isolated from the background music. I’m thinking about the Leia Hologram speech in particular. I’ve attempted to use the six channel AC3 file to isolate the vocals, however this is a very imperfect solution.

I’ve also attempted to use the noise reduction tool in Audacity to remove the music in this scene, but it always garbled the voice as well.

There is a way to isolate and eliminate the music in a scene, and this involves having an identical recording of the music which was used in the scene itself (this must be the same recording, not just the same notes). If the music is lined up and the waveforms of the recording are inverted, the two music waveforms will cancel out, leaving the rest of the sounds relatively intact.

My question to all the audiophiles on this forum is this: Does the original LP (or the 93 CD) use PRECISELY the same recording of any of the music in Star Wars? If not, is there any other way to isolate the dialogue?

Thanks!
