Dolby Announces Lossless Audio Technology, TrueHD

Posted by Sachin Garg on 11th September 2005 | Permanent Link

Dolby Laboratories announced a new advancement in lossless audio technology, the Dolby TrueHD.

The TrueHD is designed to be paired up with the most recent developments in high-definition optical disc formats, says Dolby. Apparently, the audio is equal to that of the “highest-resolution studio masters currently available.”

Dolby’s latest creation is currently being showcased at it’s CEDIA Expo (exhibit booth #538). The new technology is being sold as essential for next-gen hi-def entertainment, and has been adopted for use with both HD DVD and Blu-ray disc formats. Dolby TrueHD and Dolby Digital Plus technologies are mandatory audio codecs in the HD DVD format as well as optional features in the Blu-ray Disc format.

It’s a step up from the previous MLP Lossless, having introduced higher bit rates, enhanced stereo mix support, additional channels and extensive metadata functionality, which includes both dynamic range control and dialogue normalisation.
