Chris (Shazam co-founder)

Hi - This is Chris Barton (founder of Shazam). Sony's TrackID was built by licensing (and later buying) a technology invented by Philips. That tech was invented after Shazam. Shazam was the first to create an algorithm that identifies recorded music with background noise in a highly scaled fashion. My co-founder, Avery Wang, invented the algorithm in 2000.
