How Does TrackID™ Works....?

[Adadvait]

Sony is truly unbelievable.Hats off to TrackID app.Whenever I am on the go I use this to recognize different songs and this app never disappoints.

But how does this app really works?....(Really need a detail answer)..

I once google searched it and read some threads which says that the TrackID breaks the 5 second song into 2-1-2 seconds and matches the songs frequency/waveform with the Gracenote Servers...Is that it..?

Plz answer.....!!

And again plz give a detail answer..(like a scientific answer)
