What is a DDP master?
DDP file sets are an errorprotected wrapper format specifically designed for reliable optical disc replication. DDP or Disc Description Protocol is the industry standard method for delivering all of the data and metadata needed for disc replication to a pressing plant. Unlike audio CDs, DDP file sets contain error protected audio data plus all ancillary metadata or, “data about the data.” If your replication company can’t accept a DDP as the master or if you have ordered CD-TEXT I will provide you with a PMCD master.
