This is amazing! truly great explanation in the related blog post here http://willdrevo.com/fingerprinting-and-audio-recognition-wi... Does anyone know of a good explanation of locality sensitive hashing? I know there are other applications.

I've written similar code, but using image processing algorithms. You can find it here:

I worked for a company working on audio fingerprinting before (as well as image/video). I have to say it's great that we have a song (audio) recognition system that works pretty well, but the business never takes off. May be it's just my previous company as I'm not sure how Shazam is doing, but I haven't heard of them for a while

Rather then just fingerprinting recorded audio can this thing fingerprint words and passphrases that the user just says outloud?

How well would this work for spoken word instead of music?

I was surprised that a lot of my friends still have Shazam on their phones - but it's the kind of app they only need once in a blue moon.

I think this approach is probably a little too rigid for something like that, where there would be significant pitch, amplitude, and timing differences each time you say your passphrase.
