How does itunes recognise cds

In those days there were plenty of CDs it did not know, and I posted many listings to their database. Fun stuff. Metralla , Jan 29, Location: LA, CA.

It connects to CDDB, which recognizes CDs by the following process: 1 It determines the time of track 1 and eliminates all CDs which do not have their track 1 as this same length. It then asks you to make a choice. If you have a CD with a single track, it produces lots of choices, because there's only one chance to eliminate other CDs. People like me, when they input a CD and get no info, are the ones who upload track times and whatnot. I think I must be one of the few who doesn't misspell song titles every other time!

Sometimes, though, you rip a CD in iTunes and find that you've just got "Track 1" and "Track 2" on an unnamed album by the ever-popular "Unknown Artist" I prefer their earlier work, personally. Sometimes you even just get a blank space where the artist or album name should be. If you've ever seen this happen, you may wonder what causes iTunes not to have song names and how to fix it.

This article has the answer to both questions. The names of songs and albums aren't encoded into CDs. All of that information actually lives on the Internet. GraceNote is a massive database of album information that can tell one CD from another using data that's unique to every CD but hidden from users. GraceNote then supplies the information about the songs on that CD to iTunes. When you don't get any song or album names in iTunes , that's because GraceNote hasn't sent any information to iTunes.

This can happen for a few reasons:. Check your internet connection. If it's not working, re-establish the connection, insert the CD again, and see if you have song info. If you do, proceed with ripping the CD.

If you've already imported the CD but are missing all of its information, you may still be able to get it from GraceNote. To do that:. Make sure you're connected to the internet. Open iTunes, if it's not already running. Single click the songs you want to get information for. Click the File menu. Click Library. Click Get Track Names. At this point, iTunes will contact GraceNote.

If it can match the song, it automatically adds whatever information it has. If it can't definitely match the song, a pop-up window may offer a set of choices. To cancel importing, click Stop Importing. Any songs that iTunes imports before you cancel importing are added to your iTunes library.

When the songs are finished being imported, click the Eject button near the top right of the iTunes window. Once the songs are imported into your iTunes library, you can play them , create a playlist with them , and more. If iTunes now recognizes the CD, delete the iTunes shortcut and create a new one. If error correction is turned on, it can take longer to import CDs. Also make sure you have the latest drivers for your video and sound cards.
