'Name That Tune' Hotline Automated Music Recognition | |
'Name That Tune' Hotline
Researchers working for Philps in the Netherlands have worked out a way to recognise a song based on a few seconds of play. There's been two articles on this recently: Dial Up to Name That Tune Mobile Phone System Can Identify Mystery Music Basically, the entire song is split into chuncks and hashed to a unique identifier based on 'energy bands' at specific frequencies. The incoming call is then sampled, and compared to the huge database of songs. This requires quite robust pattern recognition, as many songs may sound the same from specific bars, and the noise from the phone line will not help. You can then purchase the song once it has been recognised. I'm sure Philips stands the chance of making more money from this than they invested! Doesn't it always work that way? |
