Once your mastering has been completed then a number of formats can be supplied:
You can download your masters in a variety of formats. The most popular is CD quality 16bit 44.1khz WAV files.
A DDP (Disc Description Protcol) is an image of your CD master. No CD is burnt during this process so this eliminates potential errors. It can also be downloaded/uploaded saving on time and postage costs. Please check with your replicator that they can accept this format but any reputable company will. A PC/Mac player is supplied which allows you to play, burn a reference copy and extract WAV files. More information on the DDP format can be found here.
Red Book CDR Master
Some replicators still insist on sending RedBook CDR masters and these can be provided. If supplied, ISRC codes and CD-Text can be encoded.
