What is a DDP Image?

A DDP image is a type of file format used in the production and manufacturing of CDs. DDP stands for Disc Description Protocol, which is a standardized format for creating and transferring disk images. A DDP image contains all the information required to replicate a finished CD, including the audio data, track order, and other metadata. DDP images are commonly used by mastering engineers and CD replication companies as a way to ensure accurate and error-free transfer of CD data. They are considered a more reliable and efficient alternative to traditional physical masters, such as CD-Rs or tapes.

The following information is required to create a DDP Image for your album:

  • Artist Name
