Dolby Surround 7.1

Dolby Surround 7.1 is a sound system by Dolby Laboratories which delivers theatrical 7.1 surround sound to movie-goers. It adds two new channels to current Dolby Digital 5.1. The first film to feature Dolby Surround 7.1 was 2010's Toy Story 3 by Disney and Pixar.[1][2] While most theaters worldwide today, still exhibit mainly in Dolby Digital; virtually every film that is released, as of May 2018, is mixed into Dolby Surround 7.1; while some films are adopting more Dolby Atmos mixes. Dolby 7.1, is mainly exhibited in premium large-screen formats, such as AMC ETX, Cinemark XD, and Dolby Cinema. As James Cameron's Avatar 2 is slated for release on December 18, 2020, it will be solely released in Dolby Cinema, Dolby Atmos and Dolby Surround 7.1; becoming the first film not to have a Dolby Digital soundtrack. Movie theaters will also replace most Dolby Digital sound systems with Dolby Surround 7.1 systems.
