Definition
Super Audio CD (SACD) refers to disc mastered using the Scarlet book specifications which was introduced in 1999 as a successor to standard red book Audio CDs. They have more in common with DVDs than other CD types and feature encryption that render PC dumps unusable.
Like DVDs, SACDs can be both single or dual layer. Often the first layer is made up of a standard Audio CD containing the same content as the SACD layer in order to make the disc work in a standard CD player. This layer can be dumped for redump following the Audio CD guide.
Dumping
No SACD compatible PC drives were released, so current dumping methods rely on other hardware. Methods using a PS3 or a Blu-ray player with SACD support exists, but these do not capture the full disc contents and so Redump does not currently accept SACD dumps made using these methods. DIC supports reading SACDs using a first generation PS3 drive connected to a PC, but these result in encrypted dumps only.
