FAQs
CD-Text: Information encoded on the master containing the album title and artist and the track title and artist. A few CD players capable of reading CD-Text will display this information. Therefore you should provide this information as it should appear, with spelling and upper or lower case as you would like it to be. Please note that this is not the same thing as the internet-based Gracenote CD Database, which iTunes uses to retrieve and display this information on mp3s. To enable this feature, you or your label must upload the CD-Text information to the Gracenote CDDB (see below).

UPC/EAN Codes: The barcode usually supplied by a record label or distributor. This code can be embedded in the CD data and matches the barcode printed on the outside of a CD. If your label doesn't supply a UPC/EAN code, some replication plants offer to supply one as a service.
DDP Image (Disc Description Protocol): While Redbook CD-Audio discs (the kind that will play in a CD player) are often used as Masters for the replication plant, they always contain a number of errors, which is inherent in the medium. DDP files are exact data images of your mastered project and, because of the much more robust error correction in data files, are the preferred way to deliver your Master to the replication plant. If a plant does not accept DDP Images, it is a sign that they are not truly professional and should be avoided.
