Robust and invariant audio pattern matching

The invention claims an optical with quickly and welded for accurately two audio samples matching, and whether to avoid for playing variation of the invention technologies of the transformations. The audio sample between the relation of first matched to the output different specimen a fingerprint things. (210) For generating a set of (230) fingerprint things to each audio sample (231, 232) of each other in occurred a special position (242) is. The position (242) decisions panel according to the audio sample (210) contents, wherein the fingerprint things (232) provided with a or closing the special position (242) or more partial for (222). Then to each time to matching fingerprint object decision relative value. And a relative value histogram. Discovering and counting a obvious peak, and two audio samples matched with the inlet of.
