Dolby Atmos

Dolby Atmos is the name of a surround sound technology announced by Dolby Laboratories in April 2012 and released in June of the same year, first utilized in Pixar's Brave.

History

The first installation was in the Dolby Theater in Hollywood, California, for the premiere of Brave in June 2012. Throughout 2012, it saw a limited release of about 25 installations worldwide, with an increase to 300 locations in 2013. There were over 2,100 locations as of February 2015. Dolby Atmos has also been adapted to a home theatre format.

Technology

The Dolby Atmos technology allows up to 128 audio tracks plus associated pan metadata to be distributed to theaters for optimal, dynamic rendering to loudspeakers based on the theater capabilities. That is, Dolby Atmos enables the re-recording mixer using a Pro Tools plugin (available from Dolby) or a Dolby Atmos equipped large format audio mixing console such as AMS Neve's DFC or Harrison's MPC5, to designate a particular location in the theater, as a three-dimensional placement, where each dynamic sound source should seem to be coming from. Sounds that are not dynamically moving, such as ambient sounds and center dialogues, are still separately pre-mixed in a traditional multichannel format. During playback, each theater's Dolby Atmos system renders all dynamic sounds, from the pan metadata, in real-time to make it seem like each sound is coming from its designated spot, with respect to the speakers present in the target theater. By way of contrast, traditional multichannel technology essentially burns the audio tracks into a fixed number of channels during post-production. This has traditionally forced the re-recording mixer to make up-front assumptions about the playback environment that may not apply very well to a particular theater (to the extent its capabilities differ from the mixing stage where the mixer was working).

    Atmos is an album by Czech bassist Miroslav Vitous featuring Norwegian saxophonist Jan Garbarek recorded in 1992 and released on the ECM label.

    Reception

    The Allmusic review by Scott Yanow awarded the album 3 stars stating "Garbarek does emit some passion on soprano and Vitous augments the music at times with some percussive sounds made by hitting his bass; once in awhile [sic] he also adds brief samples from what he calls "the Miroslav Vitous Symphony Orchestra Sound Library." But in general this is a stereotypical ECM date, recommended to fans of that genre"

    Fictional character biography

    Original continuity

    Atmos was the genetically-engineered champion of the planet Xanthu. When the villain Universo enacted a plan to conquer his homeworld of Earth, he had several of the United Planets' superheroes, including Atmos, mindwiped and imprisoned on a distant planet. Also imprisoned were the Legion of Super-Heroes members Saturn Girl, Brainiac 5, Chameleon Boy and Dream Girl. Saturn Girl overcame Universo's hypnosis and eventually the Legion members freed everybody.

    During Atmos' absence from Xanthu, the planetary government ordered Star Boy to resign from the Legion to replace him. Thereafter, Atmos used his powers to enthrall and romance Star Boy's girlfriend Dream Girl. His manipulation was eventually uncovered, and Dream Girl angrily left him.

    Dolby Laboratories

    Dolby Laboratories, Inc., often shortened to Dolby Labs, is an American company specializing in audio noise reduction and audio encoding/compression. Dolby licenses its technologies to consumer electronics manufacturers.

    History

    Dolby Labs was founded by American Ray Dolby (1933-2013) in the United Kingdom in 1965. He moved the company to the United States (San Francisco, California) in 1967. The first product Dolby Labs produced was the Dolby 301 unit which incorporated Type A Dolby Noise Reduction, a compander based noise reduction system. These units were intended for use in professional recording studios.

    Dolby was persuaded by Henry Kloss of KLH to manufacture a consumer version of his noise reduction. Dolby worked more on companding systems and introduced Type B in 1968.

    Dolby also sought to improve film sound. As the corporation's history explains:

    The first film with Dolby sound was A Clockwork Orange (1971), which used Dolby noise reduction on all pre-mixes and masters, but a conventional optical sound track on release prints. Callan (1974) was the first film with a Dolby-encoded optical soundtrack. In 1975 Dolby released Dolby Stereo, which included a noise reduction system in addition to more audio channels (Dolby Stereo could actually contain additional center and surround channels matrixed from the left and right). The first film with a Dolby-encoded stereo optical soundtrack was Lisztomania (1975), although this only used an LCR (Left-Center-Right) encoding technique. The first true LCRS (Left-Center-Right-Surround) soundtrack was encoded on the movie A Star Is Born in 1976. In less than ten years, 6,000 cinemas worldwide were equipped to use Dolby Stereo sound. Dolby reworked the system slightly for home use and introduced Dolby Surround, which only extracted a surround channel, and the more impressive Dolby Pro Logic, which was the domestic equivalent of the theatrical Dolby Stereo.
