Dolby TrueHD Surround Sound

 

The Leading Edge in HD Sound Quality

 

Surround sound encompasses a range of techniques for enriching the sound quality of an audio source – DVD, video, or HD television. The 3D sphere of human hearing can be virtually reproduced with specifically placed speakers and technology.

Commercial surround sound media include videocassettes, Video DVDs, and HDTV broadcasts encoded as Dolby Pro Logic, Dolby Digital, or DTS.

Multichannel music has slowly been reintroduced since 1999 with the help of SACD & DVD-Audio formats. Some AV receivers, stereophonic systems, and computer soundcards contain integral digital signal processors and/or digital audio processors to simulate surround sound from a stereophonic source.

While high-definition (HD) video has been around for about the same time, it has taken longer for HD audio formats to catch up. From the beginning, HD delivered a great picture, but due to the bandwidth constraints of entertainment media, the sound simply couldn’t match that same level of quality.

All that changed with the advent of HD disc formats like Blu-ray. These HD formats unlocked the full potential of HD by providing increased data capacity, finally making it possible to have audio every bit as spectacular as the HD video.

There was still a hole in that promise until now. Dolby TrueHD leverages the benefits of HD discs. It delivers 100 percent lossless audio—that is, audio bit-for-bit identical to the original studio master soundtrack, with none of the compromises normally associated with compressed audio. At last, you can enjoy HD surround sound that’s every bit as good as the HD picture. Finally, get ready for an unprecedented home theater experience.

You can also say goodbye to confusing and cluttered cables. With Dolby TrueHD, a single HDMI™ 1.3, our equivalent, cable is all you need for your audio and video connection.

Manufacturers worldwide are building Dolby TrueHD into Blu-ray Disc™ players, A/V receivers, and home-theater-in-a-box systems.
