Sound moves around you in three-dimensional space, so you feel like you're inside the action.
Dolby Atmos creates powerful, moving audio by introducing two important concepts to cinema sound: audio objects and overhead speakers. Together, these completely change how soundtracks are created and heard.
Traditional surround soundtracks confine all sounds to a small set of channels that can deliver sound to you from only a few perceived angles. They cannot put sound above you. Further, sounds exist only as part of a channel mix. If one sound is emphasized in a traditional mix, another must be diminished.
In Dolby Atmos, by contrast, sound can be freed from channels. It enables artists to treat specific sounds as individual entities, called audio objects. These can be precisely placed and moved by the soundtrack creator anywhere in the cinema’s three-dimensional space—they are not confined to specific channels
A Dolby Atmos soundtrack brings alive the onscreen story as never before possible. The movie’s sounds flow all around you to completely immerse you in the action, heightening the impact of the story and creating a powerfully moving cinema experience.
