Shazam Magic

On my short drive to the computer parking this morning, I tuned in to the WBGO radio station. There was a song I liked and I wanted to know what it is. Usually when this happens, I check wbgo’s web site where they have the play list, but for this I need to remember the time and I need to remember to check the web site.  This time I decided to use Shazam app on my iPhone. The app managed to tag it as one of Michel Camilo songs (why not!). This made me wonder what is the technology behind this. My initial thought was FFT on the song sample but then comparing this to every second of every song would be impractical. Quick google search reviled the academic paper written by someone from Shazam and a good explanation by this blogger. Very impressive technology.
