Dolby Atmos

Definition

Dolby Atmos is an advanced audio technology that provides an immersive sound experience by allowing sound to move freely around a listener in a three-dimensional space. Unlike traditional surround sound systems that assign sounds to specific channels, Dolby Atmos uses object-based audio to position sounds anywhere in the environment, creating a more realistic and engaging listening experience. This technology enhances sound editing and mixing, allowing for greater creative possibilities in audio production.
