I am looking for a sound bite from the texas chainsaw massacre movie.

At the start of the film (also the new one as well) they have camera shots of a corpse, and theres like this high pitch noise which builds up in short spurts and is played a few times in the intro with the pictures ebing taken. I think might be something to do with the camera or something, but i am not sure. Its hard to explain but it's at the very start of the movie, after the prolouge/intro.
i think it's one of the creepiest sounds, and it always gives me chills

Anyway, could i download this anywhere? or another thing is are there any good dvd audio rippers that are free, just so i could rip it off of the dvd instead (cause my brother owns it?)
any good recommendations?

thanks
