What type of sound technology does a Blu-ray Disc use?

Disney Blu-ray offers stunning sound quality that DVD can't match. This is the way movies were meant to be heard!

DTS-HD Master Audio can be found on most Disney Blu-ray Discs and delivers a soundtrack that is bit-for-bit identical to the original master recording. With up to 7.1 channels of surround sound, DTS-Master Audio places you in the center of the action!

Dolby True HD is another technology which delivers up to 7.1 channels of perfect surround sound identical to the original master recording. Dolby True HD can be found on National Treasure 2 and Enchanted on Blu-ray today!

Uncompressed PCM offers a truly uncompressed soundtrack identical to the master recording. Uncompressed PCM can be found on classic Blu-ray Discs such as Cars and Pirates of the Caribbean: The Curse of the Black Pearl.
