Digital dts sound in selected theaters12/11/2022 Not all movies are, and you can find a list of such movies on the Movies Mixed in Barco's 3D Sound page. ![]() In order to take advantage of an Auro 11.1 sound system in a theater, the movie must be encoded with an Auro 11.1 soundtrack. Announcements have been made by some of the major theater chains to install more systems across their circuits, so we expect that number to increase in 20 to the point where finding a movie playing in Auro 11.1 should become easier. As of January 2014, there are 27 North American theaters with Auro 11.1 sound systems installed. Originally known as Auro-3D®, the Auro 11.1 sound format takes the traditional 5.1 channel layout and adds two vertical layers of sound a height layer which is above the traditional layout, and an overhead layer which ceiling mounted to provide overhead sound effects.Īuro 11.1 was introduced in September 2011, with Red Tails being the first movie carrying the soundtrack. If theaters indicate that their presentation is in Dolby Surround 7.1, we add the logo you see above to the showtimes for that movie at that theater. Dolby Surround 7.1 is the marketing name that was given to the 7.1 channel sound format, but nothing about it is unique to Dolby technology or equipment. Dolby Surround 7.1 is only available with Digital Cinema Projection systems.Īn interesting note about this sound format is that the ability to produce 7.1 channels of sound is built into every Digital Cinema Projection system. Dolby Surround 7.1 takes the rear surround channel as described in Dolby Digital Surround EX (below) and splits it into two channels. In 2010, Dolby Labs worked in conjunction with Walt Disney Pictures and Pixar Animation Studios to introduce a new sound format with their release of Toy Story 3. Just look beneath the showtimes to see designations for 7.1 channel digital sound. We rely on the theaters to provide this additional information in the showtime comments. It is marketed by Dolby Labs as Dolby Surround 7.1, even though no Dolby-specific technology or equipment is involved in the process (see below). This sound format does not have an official designation, so many theaters just refer to it as "7-channel digital sound" or something similar. This allows for more localization of sounds as they pan behind the listener and can help when action flies overhead, since the sound can move from in front of you to behind you, causing your brain to fill in the gap above you (to a certain extent). It splits the traditional two surround channels into four, so you now have two side surround channels (left and right) as well as two rear channels (left and right). 7.1 Channel Digital Soundħ.1 channel sound for Digital Cinema was introduced with the 2010 release of Toy Story 3. ![]() ![]() Since this can be anywhere between 1-12 channels, it is up to the theater to specify if they are doing something other than the traditional, expected format of 5.1 channels (3 front, 2 surround, 1 subwoofer). Digital SoundĪll sound that you hear during a Digital Cinema presentation is stored and delivered digitally, as mentioned previously. Think of film-based digital sound being similar to an MP3 file and digital cinema sound being like a multi-channel CD. The sound is compressed losslessly, which means that there is no compression used that removes any of the original sound that was produced in the studio. All Digital Cinema Projection systems output sound digitally, whether it is one channel or up to 12 channels that is allowed by the Digital Cinema specification. The movie theater industry is transitioning itself to using Digital Cinema Projection systems, which means that film has been replaced by digital files provided by a computerized server.
