For instance I would like to tell with what percentage of accuracy a recorded sound match those given by a preexistent library of sounds
Plus, is there any tool or algorith that could be used?

1Are you looking for audio tools that will do this for you, or DSP techniques? If you are looking for DSP techniques, then consider moving this question over to signal processing.– ObscureRobotCommented Nov 15, 2012 at 19:19

I wasn't aware of that site, but an out-of-the-box tool would be very helpful, thoug– rraallvvCommented Nov 15, 2012 at 19:29

I don't know of a good tool offhand, but hopefully someone else does.– ObscureRobotCommented Nov 15, 2012 at 19:29

Shazam (and various others) do this for entire songs. This paper describes how:
- Beforehand, Shazam fingerprints a comprehensive catalog of music, and stores the fingerprints in a database.
- A user “tags” a song they hear, which fingerprints a 10 second sample of audio.
- The Shazam app uploads the fingerprint to Shazam’s service, which runs a search for a matching fingerprint in their database.
- If a match is found, the song info is returned to the user, otherwise an error is returned.
I would imagine for short sounds you would do similar but sample much more frequently.

Well the idea is there but thats not going to work for what he is asking for...unless he is doing music that is not going to work– Chris James ChampeauCommented Nov 16, 2012 at 23:40

I'm not into doing it myself at this moment, but it's good to know it is possible. I've installed the app in my phone, and the results are amazing. I guess the question that could suit better my requirement is ...is it posible? etc.. etc– rraallvvCommented Nov 17, 2012 at 1:25

Yes of course it is possible, I would say you would have to take a look into the Shazam API and then go from there– Chris James ChampeauCommented Nov 19, 2012 at 23:03
