Dolby® Digital 5.1 Creator Consumer Encoder

Dolby® Digital 5.1 Creator is an efficient audio coding technology that lets consumers record high-quality Dolby Digital 5.1-channel audio onto devices such as camcorders and hard disk recorders. Dolby® Digital 5.1 Creator is a version of Dolby Digital perceptual audio coding optimised for consumer applications, making it possible to store high-quality digital sound far more efficiently than it is to store conventional PCM recording. It is an audio standard for recording video on DVD, Blu-ray DiscT, AVCHD-based camcorders and digital still cameras.

The ESPICO implementations are based on the Dolby reference model with proprietary optimisations to reduce memory and MHz requirements. Contact ESPICO for specific resource requirements.
