Dolby Surround 7.1 adds two discrete channels of sound to increase the realism of all types of movies.
With two new channels of sound, Dolby® Surround 7.1 extends the creative palette for filmmakers and enables movie sound that better matches the onscreen action.
Greater control of the sound placement allows filmmakers to better match the audio to what takes place onscreen.
Dolby Surround 7.1 enhances audio definition, so individual sounds are clearer and more distinct.
Dolby Surround 7.1 improves the surround sound experience across the entire theatre by widening the listening "sweet spot."
Surround sound introduced a whole new element to the cinema experience—the chance to feel immersed in a scene and part of the action.
Dolby Surround 7.1 increases the impact of surround sound by adding two audio channels. In the process, it improves the spatial dimension of movie audio and enhances overall audio definition for movie soundtracks.
One of the innovations of Dolby Surround 7.1 is the creation of four distinct surround zones in the theatre. These surround zones provide filmmakers with greater control over the exact placement of each detail in their soundtracks.
The orchestration possibilities that Dolby Surround 7.1 introduces allow mixers and sound designers to more accurately match their audio to the visuals onscreen. This means more depth and greater realism for you at the movies.
In addition to improving the side-to-side panning of sounds and sound localization, Dolby Surround 7.1 enhances audio definition, so you hear individual sounds more clearly and distinctly. It also widens the listening "sweet spot"—in other words, the full power of Dolby Surround 7.1 is not limited to a handful of seats in the center of the theatre.
Dolby Atmos® is the latest, most lifelike audio experience for the cinema.
