Dolby Atmos

Definition

Dolby Atmos is an advanced sound technology that creates an immersive audio experience by allowing sound to be placed and moved in a three-dimensional space. This technology enhances the traditional surround sound system by adding height channels, making audio feel more realistic and enveloping.
