Audio Fingerprinting implementation on iPhone

It's the first time I post a question in a blog, but it seems to me this is the best resource on the web for that.

I'm looking for a way to implement audio fingerprinting in an application for iPhone. I had a look at the lastfm fingerprinter, being that I already use other lstfm api calls, but porting it to the iphone seems to be a mess and I'm quiet sure that it would be highly inefficient.

Should I give the search for now as I am looking for a free service ,I'm a young private developer and don't have sufficient economic resources for a payed service. This is also the reason for which I cannot install the library on my web server and run it remotely, sending just the audio data to it. The hosting I rely on dosen't allow me to install third party applications...

Musi开发者_JS百科c Brainz seems to be a solution, but not quiet sure on how to obtain the fingerprint...

Any suggestions, hint, tips, links, search queries, anything?

Thanks in advance!

Check out Echoprint, an open source audio fingerprinting service provided by Echonest.

Here is the iOS example they provide on their echoprint github repo.
