Gracenote • What it is? • CD identification service • Where and how it is used • iTunes, WinAmp, etc. • Identifies whole CDs, not individual tracks source: http://en.wikipedia.org/wiki/Gracenote image: http://en.wikipedia.org/wiki/File:Gracenote_logo.png
CDDB - How Gracenote works • XX = Checksum of pre-track silences • YYYY = Duration • ZZ = # of tracks • Example: • 2b1ae209 • 2b total seconds pre-track silences, 1ae2 total seconds, 9 tracks. source: http://en.wikipedia.org/wiki/CDDB
Consequence: • Two CDs with the same: • Total length • Number of tracks • Sum of pre-track silences • Will be identified as the CD!
