Three things that you’ll want your master audio CD to have are ISRC encoding, CD-TEXT, and finally to have the CD information submitted to the Gracenote CD Database. Crystal Clear Sound offers Digital Formatting for just $25 per disc. Of course if you’re getting your project mastered at Crystal Clear Sound then we do all of this at no additional charge. Below is a little information to explain the three parts of Digital Formatting.
International Standard Recording Codes (ISRC) are used if you plan on using digital distribution methods such as iTunes or Amazon Music or intend to make your music available for internet radio. Each song is given its own unique code (this is different from UPC as that is for physical CD sales). To learn more about ISRC codes you can read about them here http://www.usisrc.org/faqs/general.html
CD-TEXT is encoded into the metadata of the audio CD and allows CD-TEXT enabled car stereos to display the artist, album name, and song titles as the CD plays.
The Gracenote CDDB is the CD database used by iTunes and some other web connected music players. When a user inserts your CD into their computer and opens iTunes the software then goes online to the Gracenote CD Database to find the information for the CD. It then pulls that information back to display in the iTunes software. The Gracenote database uses the CDs table of contents (not CD-TEXT) and compares the CD in the drive to the database to find the nearest match, this is why you will occasionally get multiple matches and need to select the correct CD from the list.
