Dolby Digital is a digital audio technology developed by Dolby Laboratories. It is a surround sound format that is widely used for home theater systems, DVDs, and Blu-ray discs. Dolby Digital uses 5.1 channels of audio, consisting of front left, front right, center, surround left, and surround right, with a low-frequency effects (LFE) channel for the subwoofer.
Dolby Atmos, on the other hand, is an immersive audio technology that takes the surround sound experience to the next level. It was introduced by Dolby Laboratories in 2012 and is designed to create a three-dimensional sound space, where sound can be placed and moved in any direction, including overhead. With Dolby Atmos, sound objects can be precisely positioned in a virtual space, providing a more realistic and immersive audio experience.
Unlike traditional surround sound, where audio is mixed into channels, Dolby Atmos uses "object-based" audio. This means that audio can be placed in a 3D space and moved dynamically, providing a more natural and immersive audio experience. Dolby Atmos is used in theaters, home theater systems, and even in some mobile devices.
