Why Dolby Atmos" Whitepaper
Why Dolby Atmos Why Dolby Atmos 08—2020 Your story made better in Dolby Atmos Dolby Atmos has become the immersive audio standard for film and television content creation. Introduced first in the cinema, Dolby Atmos has been adopted by the most popular streaming services such as Apple TV+, Disney+, and Netflix, and is also being made widely available to mainstream audiences on millions of consumer playback devices. Once used primarily on big-budget Hollywood films, Dolby Atmos is being leveraged by content creators on a wider variety of content genres and types than ever before. This is your opportunity to hear first-hand from some of those content creators on how Dolby Atmos has enabled them to enhance their stories. This paper will demystify what Dolby Atmos is and why content creators should be creating all of their content in Dolby Atmos. “Dolby Atmos is a format and not a particular sound. At Netflix, we feel the best mixes come when mixers have excellent technology and the freedom to use it in a way that best tells the story.” — Scott Kramer | Netflix Dolby Atmos: From cinema to home First utilized on Pixar’s 2012 film, Brave, Dolby Atmos introduced a new paradigm of audio creation and delivery in cinema, enabling filmmakers to fully immerse moviegoers in their story’s soundscape. Today, that paradigm has also revolutionized the home entertainment experience, bringing Dolby Atmos technology to the living room and enabling content creators to immerse viewers more deeply into their stories. Many of today’s leading content services and their studio partners have adopted Dolby Atmos on feature films and episodic titles. -

Dolby Atmos for the Home Theater
Dolby Atmos® for the Home Theater October 2014 Dolby Atmos®, the revolutionary cinema sound technology, has come to home theaters. With Dolby Atmos, content creators can precisely place and move sounds anywhere in your living room, including overhead, to make entertainment incredibly immersive and lifelike. This white paper is designed to explain how Dolby Atmos will work in home theaters and how you can build a Dolby Atmos enabled system or upgrade your existing system to support Dolby Atmos. This paper also explains the technological components of Dolby Atmos in home theater and the tools that content creators and broadcasters will use to create and deliver Dolby Atmos content to homes. Why replace channel-based surround sound? Dolby Atmos is a revolutionary technology that moves beyond the paradigm of channel- based audio, which has gone as far as it can in the home. Dolby has led home theater technology since the late 1980s, when we introduced four- channel Dolby® Pro Logic®. We led the development of 5.1 and then introduced 7.1 surround sound in the home and the cinema. But as home theater expanded to 9.1 and even 11.1 systems, the problems of pursuing more and more channels became clear. Home theater content often originates from theatrical content that is mixed, at best, in 7.1 sound and many times in 5.1. That meant that 9.1 or 11.1 systems reached a point of diminishing returns in parsing and upmixing that limited signal to serve more and more channels. In addition, the ability to recreate reality using channel-based audio is inherently limited. -

Dolby Atmos® for Compact Entertainment Systems: Immersive Surround Sound from a Stereo Form Factor
Dolby Atmos® for Compact Entertainment Systems: Immersive Surround Sound from a Stereo Form Factor November 2016 Dolby Atmos® is a revolutionary cinema sound technology that has come to home theaters, bringing a new and exciting sense of total immersion and reality to your favorite movies, music, video games, and other programming. With Dolby Atmos, content creators now have the tools to precisely place and move sounds anywhere in your living room, including overhead, to make entertainment incredibly immersive and lifelike. Dolby Atmos is based on the concept of sound objects. Every sound in a scene—a child yelling, a helicopter taking off, a car horn blaring—can be represented as an independent and discrete sound object. Each of those sounds comes from a specific location in the scene, and in some cases, they move. Using sophisticated content creation tools that represent the sound objects in a three-dimensional space, filmmakers can isolate each of the sound objects in a scene and decide exactly where they want it to be and how they want it to move. In the final sound mix, the sound objects are combined with positional metadata—additional data that describes a variety of parameters about the sound object, including its location, its size and movement, if any. During playback of a Dolby Atmos soundtrack, the object audio renderer (referred to as the OAR and a key ingredient in Dolby Cinema™ processors and home theater playback devices) references the positional metadata in the mix to scale the object-based audio presentation to the specific speaker layout in the room. -
