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.Īs a result, a Dolby Atmos soundtrack brings alive the onscreen story as never before possible. These can be precisely placed and moved by the soundtrack creator anywhere in the cinema's three-dimensional space, though the artist can continue to use channel capabilities as desired. It enables artists to treat specific sounds as individual entities, called audio objects. In Dolby Atmos, by contrast, sound can be freed from channels. If one sound is emphasized in a traditional mix, another must be diminished. Further, sounds exist only as part of a channel mix. Traditional surround soundtracks confine all sounds to a small set of channels that can deliver sound to you from only a few perceived angles.
Together, these completely change how soundtracks are created and heard. Dolby Atmos® creates powerful, moving audio by introducing two important concepts to cinema sound: audio objects and overhead speakers.
