track id recognition allows a person to know everything about a music track with the help of gprs just by keeping the mobiles mic close to music source
The TrackID analyzes audio from recorded music from the phone and then submits that audio sample to the TrackID service. The Gracenote service compares a "musical fingerprint" generated from the audio sample against an enormous database of fingerprints containing 2.5 million songs which covers the global music market. The fingerprint is matched and the listener is sent the song name and artist info.
