The core algorithm is well known and fun to implement:

A blog had a simple implementation of it and were contacted by Shazam's lawyers:

- Cyph0n 10y agoDolby and Philips also have a bunch of patents. It seems like basically any version of audio fingerprinting has been patented. So unless you can come up with a fundamentally different algorithm, you're going to get sued.

- bogomipz 10y agoThanks for the links. I know in the US patenting an algorithm is legal but this is not the case in Europe where patenting any software is not legal. If this was the case I wonder why streaming services based in Europe such as Spotify or Soundcloud don't offer it considering the algorithms are well known.
- ptzz 10y agoI think the claim of it being impossible to patent algorithms in Europe is a bit overstated. In my experience, you just add "Method and apparatus that implements <whatever_algorithm>" and it's granted. Pretty sure Shazam/Philips/Dolby patents cover Europe.
