Starlight Presented in Dolby Atmos
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. 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—though the artist can continue to use channel capabilities as desired. The Dolby Atmos cinema processor then determines which of a cinema's huge array of front, back, side, and overhead speakers it will use to recreate this lifelike movement.
