However, equipping a cinema for immersive audio is an expensive business. The Atmos mantra is 'author once, optimise everywhere.' The post production process automatically creates 5.1 and 7.1 mixes of a movie, and it's these that are used for unmodified cinemas and home video distribution. KILLER." Winning over Hollywoodĭolby is banking on the fact that mixing in Atmos doesn't impose significant time or creative penalties on a studio's existing workflow after all, time is money.
He excitedly tweeted afterwards: "Was given a demo Dolby today of sequences from INCREDIBLES & MI:GP remixed in their brand new top secret system. The result is a more natural and immersive soundfield the days of crude overhead pans are audio history.Īcademy Award winning director Brad Bird was given a preview of Dolby Atmos earlier this year. Engineers can place an audio object anywhere spatially, with a precision impossible in conventional 5.1 mixes. Dolby Atmos achieves this immersive innovation by combining additional sound channels with object based steering. The process is called adaptive rendering. In Dolby Atmos every element in the frame can be a separate sound object, able to be placed anywhere to create an immersive soundfield If that speaker fails, or you have far fewer speakers in an auditorium, then the system calculates where it needs to create a phantom speaker, so that the sound still appears in roughly the same space."
"If you have a hundred speakers down one wall, you can have the sound come from the exact speaker specified by the movie's sound designer. ''Suddenly every element in the frame becomes a separate sound object," he says "and the resulting soundtrack gets mixed on the fly at each and every cinema, depending on the speaker configuration in the theatre. He told Tech Radar that systems such as Dolby Atmos not only change the way films are experienced, but fundamentally alter the way sound designers think about mixing movies. Datasat makes the AP20 cinema sound processor, used in theatres worldwide, and has just launched a new high-end home cinema processor based on it, called the RS20i (yours for a cool £16k). He's more familiar than most with the next generation of 3D sound formats.
