Dolby Laboratories Debuts Dolby TrueHD
September 08, 2005
Indianapolis, IN - Dolby Laboratories at CEDIA EXPO today announced its latest advancement in lossless audio technology, Dolby TrueHD, which is designed to complement the recent developments in high-definition optical disc formats. With Dolby TrueHD, the company says that home theater viewers will experience audio performance equal to the highest-resolution studio masters currently available.
Dolby says that these two technologies are essential elements of next-generation high-definition entertainment, having been adopted for use in both the HD DVD and Blu-ray Disc formats. According to the company, 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. They add that Dolby Digital is mandatory in both formats.
"The high-definition disc formats being discussed today will provide viewers with new levels of image quality," said Craig Eggers, Dolby Senior Manager, Consumer Electronics Technology Marketing. "With Dolby TrueHD, those same viewers can experience multichannel surround sound that fully complements the detail and fidelity of the high-definition picture."
Dolby TrueHD builds upon the foundation of MLP Lossless(TM) by incorporating higher bit rates, additional channels, enhanced stereo mix support, and extensive metadata functionality, including dynamic range control and dialogue normalization. Enabling recordings that are bit-for-bit identical to studio masters, according to the company, MLP Lossless was first introduced in DVD-Audio, and has since become the leading multichannel lossless audio format, according to Dolby. In addition, the company says, Dolby TrueHD provides support for all of the new speaker locations designated by the Society of Motion Picture and Television Engineers (SMPTE) for digital cinema applications (RP 226).
"When coupled with high-definition video, Dolby TrueHD offers an exceptional home theater experience that enables you to enjoy sound as stunning as the picture," said Ed Schummer, Senior Vice President and General Manager of the Consumer Division, Dolby Laboratories. "When a playback system displays the Dolby TrueHD logo, viewers are assured they are hearing the highest-quality audio performance possible -- as if they are hearing the studio master itself."
