Tool for finding an audio snippet in a bigger collection of recorded audio

[Rainer Straschill <moinsound@googlemail.com>]

This is really OT, but also, if not here, then where would I find one 
who could help me with something like this...

Some time ago, I had copied a snippet of audio out of a large pool of 
recordings (around 50-100 hours), compressed it and used it as a system 
sound. Now I want to find that source again, to work with that snipped 
(unprocessed) and its surroundings.

So I need something of a tool that would cross-correlate some, but will 
find the snippet in the source files even though the snippet is much 
hotter (not necesarrily into clipping, but rather from a -30dB to a -8dB 
RMS or something) than the original.

Anyone knows of a solution for this, other than listening through the 
whole 50-100 hours?
