Dolby Immersion

I’ve finally figured out what the big deal is with Dolby Surround 7.1, which is not new and has actually been installed in some 2100 theatres. But until tonight I didn’t fully understand what makes this sound system a distinctive development. The ins and outs were discussed this evening by several sound specialists at a Dolby headquarters seminar in San Francisco, but I didn’t really get it until I spoke to Dolby marketing manager Stuart Bowling after it ended.


At this evening’s Dolby Labs seminar on Dolby 7.1 Surround: (l. to r.) Eric Brevig, Skywalker Sound’s Michael Semanick, Transformers 3/Tree of Life sound designer Eric Aadahl, director-producer Rohan Sippy, sound designer Kinson Tsang, and (far right) Stuart Bowling, Dolby Laboratories technical marketing manager.

So here’s the shot in layman’s terms. Dolby Surround 7.1 basically delivers super-clear, highly immersive sound from four discreet sound “zones” — front, left, right and rear. But that’s what Dolby 5.1 delivered, right? No, there’s a difference. To really hear all four channels with Dolby 5.1 you had to sit in a theatre’s “sweet spot,” which is more or less dead center. Dolby 7.1 delivers loud and distinct super-quad sound in almost any section in the theatre. You don’t need to be in a sweet spot to really hear it. So there you go. That’s the thing.**

Early this evening Dolby management and publicists hosted an elegant dinner on the third floor of company’s headquarters on Potrero Street. I arrived a bit late due to my Burbank-to SFO plane being delayed by fog. The seminar, an agreeably informative thing, lasted for a couple of hours. The panelists were Eric Brevig, Skywalker Sound’s Michael Semanick, Transformers 3/Tree of Life sound designer Eric Aadahl, director-producer Rohan Sippy, sound designer Kinson Tsang, and moderator Stuart Bowling, Dolby Laboratories’ technical marketing honcho.

I asked a question about how everyone at sound seminars always talks about creating big, loud soundtracks for big tentpole blockbusters while I prefer subtle, more human-level sounds, and that the world of aural cinema (including the realm of Dolby Surround 7.1) is far too vast and delicate and all-encompassing for seminars like this one to focus only on the sounds of explosions, blam-blams, face-punchings, rib-punchings, gunfire, helicopter blades, and blah, blah.

There’s a breakfast tomorrow morning from 8 am to 9 am, and then Ioan Allen‘s “The Egg Show” (i.e., some kind of instructive lecture about the history of sound design) and then a lunch and bunch of other seminars and screenings of Legend of the Fist: The Return of Chen Zhen and Dum Maaro Dum and then a cocktail party from 8 pm to 10pm and so on. A very full day.

** Dolby Surround 7.1 is also savorable through Bluray and other non-theatrical modes with the same four-channel discretion.
