Dolby Atmos is a surround-sound technology developed by Dolby Laboratories that allows you to experience multi-dimensional sound with incredible clarity that brings you deeper into the story. It expands on existing surround sound systems by adding height channels, allowing sounds to be interpreted as three-dimensional objects with neither horizontal nor vertical limitations. With Dolby Atmos, sound can be precisely placed anywhere in the cinema, even overhead, creating an immersive soundscape that sounds more like real life. The technology was initially created for commercial cinema applications, and was later adapted to home cinema.

Key features of Dolby Atmos include:

• Audio objects: Dolby Atmos introduces the concept of audio objects to cinema sound, which allows content creators to control distinct sound elements in a soundtrack to the traditional channel-based approach for mixing.

• Overhead speakers: The most immediately noticeable difference in a Dolby Atmos system is the use of overhead speakers, which allows sound to move around you in three-dimensional space.

• 128 discrete audio tracks: The first-generation cinema hardware, the "Dolby Atmos Cinema Processor", supports up to 128 discrete audio tracks and up to 64 unique speaker feeds.

Dolby Atmos is available in select movie theaters and home theater systems. It is designed to create a powerfully moving cinema experience that brings you deeper into the story.
