> How does Track ID work?
Bookmark topic
I cannot figure this out, I can pick any part of any song and most times it can match it. I know it goes online to do this, but how on Earth is it done?
I was thinking of the frequency range, of each song being different, but there are so many and the frequency range would change depending on what part of the song you are listening to.
Am I missing something here!?
ps has anyone had TrackID come back with an incorrect song?

Right ok, I tried to confuse Track ID by playing an old techno song (12") to see if it could tell the difference between the 12" and the standard song.
I recorded part of the song which is in all versions( just the beat)
It not only knew what song it was, but it told me which version of the 12" mix it was !!!
THATS IMPOSSIBLE!!!

Basically it uses the 5 second sample and sends it to the Gracenote server in the US (World's biggest music database) and then searches for a match of the 5 second waveform with the waveform of the millions and millions of songs on the server.
It's like when a police computer tries to match a fingerprint. The Track ID smaple is converted into frequency data and is virtually a unique fingerprint to all music.
The real question is how can it do all this within 10 seconds?
It also works with music from overseas.. Indian, Chinese, Arabic, Turkish music...
Truly amazing.

Converting the TrackID into a frequency would only work if the 5 second sample equalled what is stored on their servers, but you can pick any part of the song to sample, therefore the frequency could be different each time
With fingerprint ID, there is only 1 source(which never changes)
Still does not explain how it can differentiate between different versions of the same song, where the sample is identical in various versions. ( or seems to be)
Headache is looming, lol

ok well i tried track id for the first time 2 days ago to find the names of a couple of songs from a Sander Van Doorn live set (a dj for those who dont know who he is) but it didnt identify the song. Came back with NO results at all. Was in a very quiet environment so nothing was blocking the sound......
also tried it in a club on saturday night, but again came back with no results at all, and it was a fairly commercial song. maybe coz it was quite noisy

I tried it in a noisy t-mobile shop and it came back with a lemar tune correctly. It is a big magic isn't it.
Is there nothing on wiki about it?

Anyone know of a way to get this as a java app perhaps or add it on a K790? The initial info released had it listed as a feature but it's not even available on the prototype (which I have)

Does TrackID cost anything like Shazam does?

it only costs you the data consumed (i.e. gprs/3g etc)
