Dolby Atmos
Dolby Atmos is a proprietary, object-based surround sound format that was introduced by Dolby Laboratories in April 2012 . It requires the extension or modification of the speaker configuration of existing home theater systems.
technology
The Dolby Atmos technology theoretically allows an unlimited number of sound tracks. In contrast to the purely channel-based surround formats, vector-based metadata for moving objects can be included in the data stream , the coordinates of which are then calculated by the receiver in relation to the respective speaker setup. The first generation of hardware, the Dolby Atmos Cinema Processor , supports up to 128 individual sound tracks and up to 64 separate output signals.
An essential component of the system is an extension - or a partial replacement - of the existing loudspeaker system, whereby either up to four loudspeakers are positioned on the ceiling of the listening room, or the previous loudspeakers of the home theater system are supplemented / replaced or replaced by "Dolby Atmos Enabled Speakers" to be modified. If four ceiling speakers are used, a previous 5.1 system becomes a 5.1.4 system, and a 7.1 system becomes 7.1.4.
By expanding the speaker set, a realistic simulation of rain or helicopters, for example, is possible. Dolby Atmos is backwards compatible with older systems such as 5.1 or 7.1 .
With Blu-ray discs , a 7.1 sound bed with embedded objects is used as the starting configuration for an Atmos mix, in which objects are moved individually. Playback is intended for a room with a maximum 9.1.6 configuration. Dolby Atmos information is then played back in the Dolby TrueHD codec as metadata via an audio receiver; without Atmos configuration, ordinary 7.1 or 5.1 is played back. A Dolby Atmos soundtrack is created using a plug-in for Pro Tools and a system called Dolby RMU. Either the finished sound is simulated or played in a small room with Atmos speakers.
history
The first cinema in which the new technology was also used for demonstration is the Dolby Theater in Hollywood , California . In June 2012, Pixar's Merida - Legend of the Highlands was the first film to use the new system. In the same year, 25 cinemas worldwide were equipped with the system. It was planned to expand the distribution to around 1000 locations by 2013.
At the beginning of 2013 there were already two cinemas with the technology in German-speaking countries. Initially, the focus was on commercial cinemas, with later adaptation for home theater installations .
While the first films had to be remixed in the new sound system for Atmos, Joseph Kosinski's Oblivion (2013) was the first film to be mixed directly in Dolby Atmos and in which the 5.1 and 7.1 sound was derived from the Atmos sound. The first German film that was mixed directly in Dolby Atmos was Lost Place .
In September 2014, Transformers: Age of Extinction was released as the first Blu-ray Disc with a Dolby Atmos soundtrack.
Dolby Atmos is now also being integrated into smartphones in the form of equalizers.
Since 2019, the Sony TV model BRAVIA AG9 has been equipped with an Acoustic Surface Audio which is improved compared to the AF9 and which now also supports Dolby Atmos.
