Acoustic Audio Comparing Library

Question

I need a software or a library which handles with audio comparison, but not using the tag's inside mp3 ,it should compare similarity or confidence between 2 audio Files, or if i cut a piece from an audio file, the software should point where is that file token from the main audio file (i hope i was clear enough).

So how i heard this technology is called Audio Acoustic Comparing, and based on some audio sample file, which we can call fingerprint. The software should point me if it finds an equivalent of the input sample or fingerprint, somewhere in the file.

Bests.

AFAIK shazam is patented, and the patent holder enforces the patent. – CodesInChaos Feb 04 '11 at 14:45
Is this really a solution to the question which parts of the audio files correspond? – Sney Jun 22 '11 at 19:33
@Sney I think this one can't give you a good similarity measure, but it most likely can tell you which parts of an audio file are similar. – CodesInChaos Jun 22 '11 at 19:37
