A DDP (Disc Description Protocol) is a specialized folder containing all the data needed to replicate a CD. It acts as a digital 'master' that ensures the sequence, timing, and metadata of your album remain exactly as intended by the mastering engineer. While no longer needed for digital distribution, it remains the industry standard for professional CD manufacturing.
- 1.Use a DDP for physical CD manufacturing to ensure 'Red Book' compatibility, which guarantees the disc will play in any standard CD player without errors.
- 2.Provide a DDP to the replication plant to lock in metadata like CD-Text (artist/title info), ISRC codes, and precise track spacing/crossfades.
- 3.Skip the DDP if you are only releasing on streaming platforms (Spotify, Apple Music), as they require individual high-resolution WAV files rather than a single disc image.
- ×Burning a standard 'Data CD' or 'Audio CD' at home is not a substitute for a DDP; physical discs can suffer from 'bit rot' or write errors during shipping.
- ×Ensure your mastering engineer has included the ISRC codes in the DDP metadata, as these cannot be added easily once the glass master is made.
Always request a 'DDP Player' from your mastering engineer. This is a small application that allows you to listen to the DDP exactly as it will sound on the CD, ensuring the gaps and transitions are perfect.
