I am not sure if it's really possible but I've always wondered how radio stations seem to be able to rip the backtrack of a song out without the lyrics - -

I am wondering how to do something similar except with dialogue - - For instance - - I am trying to capture a portion of dialogue from "The lord of the rings" but the section has some music behind it that I would prefer not to be there -

Is there a decent way to isolate just the voices and scrap the music?

any help is greatly appreciated!

Thanks -
