While obviously not the highest priority in a recording project (this won't matter to you at all if you're releasing your recording solely in the digital domain), it pays to make sure that employing this mechanism is the best way to approach your disc manufacture and subsequent release.

While audio CDs work for this purpose, they are far from. This method of transmission eliminates these potential bug-a-boos from the equation to meet a higher standard. There are two ways to deliver your master to a disk replication facility: audio CD, or DDP file. While not necessarily debilitating (All CD players/readers automatically 'correct' the simplest of them), these errors do exist on all physical discs. The file system is intended to replace a physical master disc, which can carry inherent 'errors'. The protocol was launched by Doug Carson and Associates (DCA, Inc.), who developed it to provide duplication facilities with a “consistent and complete description of the input media” used in CD and DVD manufacture. These relevant parameters include: pause gap measurements between songs, cross fades, and other salient disc information. It's a file-based system which does away with the need to submit a physical master and separate, accompanying PQ information.

It is a successor to Dolby Digital, also developed by Dolby, and has a number of improvements including support for a wider range of data rates, increased channel count and multi-program support, and additional tools for representing compressed data and counteracting artifacts. The DDP is made up of typically four files: the Audio Image (.DAT file), DDP Identifier (DDPID), DDP Stream Descriptor (DDPMS), and a Subcode Descriptor (PQDESCR). DDP Anatomy Files labeled DDPID, DDPMS, and DDPPQ (or SUBCODES) all describe and organize the disc A file that contains the audio data for the disc A file. Dolby Digital Plus, also known as Enhanced AC-3 is a digital audio compression scheme developed by Dolby Labs for transport and storage of multi-channel digital audio. In addition to the audio itself, all of the relevant data is included to ensure an album is copied onto a disc without issue.

The DDP is generally created by the mastering engineer and is the final step in the audio production chain before it’s sent off to be replicated and distributed. Many clients ask me what is a DDP and more specifically whether or not it’s something that they need.Ī DDP (digital description protocol) is a format used by most disc replication plants to create copies of an album.
