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.
