Dolby Digital 5.1 Creator is a version of Dolby Digital perceptual audio coding optimized for consumer applications, making it possible to store high-quality digital sound far more efficiently than it is to store conventional PCM recording.Dolby Digital 5.1 Creator can be built into disc-based camcorders (DVD, AVCHD, Blu-ray Disc, or flash memory), digital still cameras, optical disc recorders, and PVRs. It can also be incorporated into PC software that converts the user’s final audio mix to Dolby Digital for burning onto a recordable DVD-Video or Blu-ray Disc.
Soundtracks with 5.1 channels encoded with Dolby Digital 5.1 Creator can take up less than one-fourth the space on recording media required for stereo PCM audio, while audio quality is what consumers have come to expect from Dolby Digital media such as DVD-Videos and DTV broadcasts. A two-channel version, Dolby Digital Stereo Creator, is also available when only stereo audio is required.
Two-Channel PCM Audio (Red Book CD Standard): 1.4 Mbps
