vcast and autoid'ing songs

I saw an interesting commercial last night from Verizon. It encourage people to be "music hunters", and they can use their Vcast phone to ID music coming off of store speakers etc., Vcast will identify the music and then let them download out [assuming it's available].

I thought this was pretty cool. Anybody know how this works? I assume that however the CDDB info is found on the internet applies to wireless networking. It would be cool as I listened to my favorite jazz programs to point a device at them and autoid them; although a lot of this music is not readily available.

Yep, but it would take to long to explain here.

The technique is called acoustic fingerprinting and it's a kind of music information retrieval.

I believe that this is a completely different scheme than the one ccdb (gracenote) uses; I'm pretty sure ccdb uses song lengths & number of tracks.

Thanks for the info. I'm impressed that the acoustic fingerprinting is accurate enough to be considered forensic.
