    Default How smart is CDDB?

    OK, I recorded an analog LP to a hard drive through a sound card. Initially it was one long file then I edited it into individual tracks and burned a CD. I was planning to manually enter the title/song info. But to my SURPRISE! the copy was correctly ID'ed through the Orange CD internet search! HOW DID IT KNOW????

    Hi Ron,

    This is called "fuzzy logic". In short, FreeDB server looks for a specific track pattern rather than for exact match. This allows better recognition of CDs printed in different countries - they often have slightly different track lengths.

    You did an accurate job cutting a recording into individual tracks, and kept songs in the same order, so the track pattern of your CD-R is so similar to the one of the official CD that FreeDB was fooled.
