Surround Sound

Surround sound changes the way you watch and listen to entertainment. Conventional stereo uses two speakers to create dimensional sound in front of you. Surround sound uses an array of speakers, placed around you, to create a complete, multidimensional sonic environment. Movies and concerts spring to life. You’re in the center of the action.

Dolby Defines Surround Sound

The first movie soundtracks were monaural (single-channel). Fifty years later, movie soundtracks were still mono. Then Dolby developed the first practical multichannel film sound format, and movie audio has never been the same.

Since then, more than 30,000 movies using Dolby® technologies have been released. Dolby 3D presentations with Dolby Atmos and Dolby Surround 7.1 sound provide the ultimate moviegoing experience.

Today, Dolby technologies bring the magic of surround sound to you anywhere. Settle in for a feature in your home theater. Watch on your PC. Enjoy music videos on the go on your mobile phone or tablet. Everywhere, you’ll get an unmatched, front-row audio experience from all your electronic entertainment.
