A file that contains the CD Text information for the discģ) DDP facilitates direct upload to clients and/or replication facilities, so CD materials costs, shipping time, and the vulnerabilities of optical media are all eliminated.

A file that contains the audio data for the disc.

Files labeled DDPID, DDPMS, and DDPPQ (or SUBCODES) all describe and organize the disc.

From this data your master can be replicated without transmission error.Ģ) A DDP 2.0 file set for a Red Book Audio CD will typically contain five components: In other words, a DDP file set is data that completely describes a CD or DVD. Here are a few points that will help you understand why, and help you get introduced.ġ) Doug Carson and Associates (DCA, Inc.) developed DDP to provide replication facilities with a “consistent and complete description of the input media” used to manufacture CDs and DVDs. The Disc Description Protocol (DDP) is a mandatory delivery method for many of the world’s biggest record labels. Perhaps the only contemporary alternative is one of the least known, most under-utilized tools in the independent music production world. In addition, the time and expense of shipping CD reference discs disconnects the otherwise limitless convenience of producing music across global boundaries using the Internet. These reasons include the cost and fragility of the materials, and the debatably relevant but indisputably real margin of error that optical media introduce.

There are, though, a number of reasons to think twice about burning a CD-ROM and mailing it to your replicator.

By the time a recording project is written, produced, and mixed, nobody really wants to consider a detail as deceptively small as how you will convey your CD master from mastering to replication.
