sound removal help

[Nirav Soni <nirav@xxxxxxxxx>]

A friend asked of me a favor, so, in turn, I've a favor to ask one of y'all.
He sent me a tape that he wanted to remove the sounds from and keep only the
voice. It contains essentially a sound that sounds like the needle falling
into the groove of a very dusty and damaged record looped, an underlying hum
and a voice that is audible but unintelligible. Sounds like something off a
Martin Tetreault record. I've very little expreience with this sort of
thing, so essentially I tried to cut out the high end. This made the voice
more audible, but more unitelliginble because the vocal articulators are
high-pitched sounds. I thought to take the sound, loop it and place it out
of phase with the original, and that might cancel the frequencies and leave
only the voice. Problem is, I have no idea how to do this. Anybody have any
advice, or alternate methods of making the voice intelligible?

Cheers,
Nirav
