Your best sound experiences in cinemas today probably involve a Dolby 5.1 sound set up. This means you have 6 separate channels of sound. Left, Centre, Right, Left Surround and Right Surround make up the 5, and the .1 comes from a subwoofer or “low frequency effects” channel. From the summer, however, Dolby are rolling out their new theatrical 7.1 system. The two extra channels added here will be Back Left Surround and Back Right Surround.
This system has been developed by Dolby, apparently in collaboration with Disney Pixar who will debut 7.1 with Toy Story 3 in “select cinemas”.
The Dolby press release is trying to ride on the coat tails of 3D’s success a little, I feel:
Dolby Surround 7.1 brings a more exciting sensory experience to audiences for 2D and gives content creators control over audio placement in a theatre when mixing 3D movies. The ability to compose audio with visual elements of 3D allows content creators to immerse the audience deeper into the movie with dramatic realism.
