A DDP (digital description protocol) is a format used by most disc replication plants to create copies of an album. 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.
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 made up of typically four files: the Audio Image (.DAT file), DDP Identifier (DDPID), DDP Stream Descriptor (DDPMS), and a Subcode Descriptor (PQDESCR). Some engineers also include a text file which gives the titles and timings for the tracks.
What I Need to Make a DDP
Want a DDP? Great, but I (the mastering engineer) need a bit of information from you (the artist) before I can proceed. This information includes:
- Album Title
- Tracklist/Track Names
- Performer/Artist Name, Songwriter Name, Composer Name, Arranger Name (typically all the same person)
- Individual Track ISRC Codes (see how to get ISRC codes)
- Album UPC Code (see how do I get a UPC code)
- Any other notes you have for me (how tracks should flow into each other, space between tracks, etc.)
DDP Info Template
I’ve compiled all of the info I need from you into a straightforward Excel or Text file which you can download below.
Download (right click and save as), fill out the template, then send it back to me with any additional notes (if any) such as how you want tracks to flow into each other, space between tracks, etc. at firstname.lastname@example.org.
