Topic(s) Shazam and Handheld Music Recognition

Shazam is an Android and iOS application that can use a device's microphone to recognize a piece of music or a TV show. The application was originally designed by Chris Barton and Philip Inghelbrecht in 1999, while they were students at Berkeley. The company Shazam was founded in 2000 and allowed users in the UK to dial a number, play a song into the phone's microphone, and receive text identifying the song played.

The method that Shazam uses to identify songs included spectography and acoustic fingerprinting. Similar methods are used for sound library management ant copyright infringement detection on media databases. In 2009, Shazam was accused of infringing on US Patent # 6941275, "Music identification system".
