built upon conventional 5.1 and 7.1 layouts. For Dolby Atmos, the nomenclature differs slightly by an additional number at the end, that represents the amount of overhead or Dolby Atmos enabled speakers: a 7.1.4 Dolby Atmos system is a conventional 7.1 layout with four overhead or Dolby Atmos enabled speakers. The simplest Dolby Atmos setup is 3.1.2, the most professional one is 24.1.10. Dolby Atmos content is authored using compatible digital audio workstation software (Dolby supplies a plug-in for Pro Tools) or a suitably equipped large format audio mixing console such as AMS Neve's DFC or Harrison's MPC5. The Dolby Atmos sound system consists of a compatible speaker system, a TV or an AV media player and an AV receiver (or preprocessor), that has a Dolby Atmos object audio renderer. During playback, each theater's Dolby Atmos system renders the audio objects in real time based on the known locations of the loudspeakers present in the target theater, such that each audio object is heard as originating from its designated set of coordinates. By way of contrast, conventional multichannel technology essentially burns all the source audio tracks into a fixed number of channels during post-production. This has conventionally forced the re-recording mixer to make assumptions about the playback environment that may not apply very well to a particular theater. The addition of audio objects allows the mixer to be more creative, to bring more sounds off the screen, and be confident of the results. The first-generation cinema hardware, the "Dolby Atmos Cinema Processor," supports up to 128 discrete audio tracks and up to 64 unique speaker feeds. The technology was initially created for commercial cinema applications, and was later adapted to home cinema. In addition to playing back a standard 5.1 or 7.1 mix using loudspeakers grouped into arrays, the Dolby Atmos system can also give each loudspeaker its own unique feed based on its exact location, thereby enabling many new front, surround, and even ceiling-mounted height channels for the precise panning of select sounds such as a helicopter or rain. Consumer implementations Home theater At the end of June 2014, Dolby Labs' hardware partners announced that Dolby Atmos would soon be coming to home theaters. Dolby Atmos enabled movies are available with Kaleidescape's movie players. A first public demo was performed at CEDIA Expo 2014 on a Trinnov Audio Altitude 32 processor.
