While not stunning in its own right, the clip demonstrated the precise control Atmos provides, with shouts, bullet hits, and the roar of passing engines coming not from vague general directions, but from extremely specific locations within the theatre.
#Dolby atmos demo full
The clip from The incredibles was played twice - once with the full Atmos mix, and then again with just the surround elements. The presentation also provided ample examples of the discrete use of Dolby's audio objects. Sound cues came from extremely specific locations The difference here, according to Dolby, is sheer power: Atmos is designed for the surround speakers to be nearly equal in power to the front speakers, creating a more robust audio environment for sound designers to work with. Back when THX first debuted, films were preceded by a swelling, resonant chord that demonstrated just how different THX was at the time Atmos provides a similar experience, with the demo clip ending in a rattling set of tones that emphasized the surround speakers. Where Atmos stood out most was in its ability to envelop the theatre and draw out specific sound elements. The speakers hanging above the audience performed as advertised - a lightning strike sounded like it was coming from directly overhead - but ultimately that's a very specific use case. So how does it sound?Ī lightning strike sounded like it came from directly overheadĭolby projected several examples of Atmos in action, including a flashy 23-second demo clip and a remixed scene from Pixar's The Incredibles, and we we left very excited about the possibilites. There's also a more immediate hook: in addition to front, rear, and surround speakers, Atmos utilizes speakers mounted above the audience. 128 different objects can play back audio at any given time, with the system dynamically adjusting what speakers represent those objects based on a theater's configuration (if 128 speakers are present, for example, each object could get its own speaker if less are available, the system will map the audio objects to the available speakers). Rather than focusing on mixing sound elements to discrete channels, Atmos instead uses what Dolby calls "objects" - virtual sound locations within a theater's physical space. Atmos is both a new way to mix audio for film as well as a system to play it back in theaters. Dolby announced its new Atmos multi-directional sound platform back in April, and today the company offered a demo of the system at the recently-renamed Dolby Theatre in Hollywood.
