Atmos, Here: Sound & Vision's First Foray Into Object-Based Sound

Dolby Atmos, the latest, “object-oriented” surround sound solution magicked up by the San Francisco technologists, has earned enough ink here and elsewhere that many of us are passingly familiar with it already. Briefly, then, object-oriented means that instead of panning discrete effects or overall mixes to left, center, right, or various surround channels, sound designers and producers can now direct sounds through a virtual listening space, letting the computer work out the details. Ultimately, of course, whether at the theater or at home, sounds still emanate from physical loudspeakers driven by physical amplifier channels, so there’s a certain amount of semantics at play here. But Atmos is scalable: A commercial theater can have as many as 64 discrete, individually addressable loudspeakers, including multiple “height” speakers in the ceiling.

Greg P. Russell Elevates Transformers

Greg P. Russell is the sound rerecording mixer of Transformers: Age of Extinction, and all of the Transformers movies actually, representing three of his 16 Oscar nominations… and counting. Since this was not only his first Dolby Atmos mix but the very first Dolby Atmos Blu-ray ever, he graciously sat down to discuss his work with Sound & Vision.

THE VERDICT
Outstanding audio capabilities and thoughtful ergonomics underpin our first Dolby Atmos–capable A/V receiver.

It’s been several years since I’ve had the opportunity to “do” a big Denon A/V receiver. So when a sample arrived of the company’s behemoth AVR-X5200W, one of the very first receivers ready to decode and distribute Dolby Atmos in a home theater setting, I was ready to begin. Atmos is the San Franciscans’ latest, “object-based,” scalable-multichannel surround format.

Transformers: Age of Extinction

Picture

Sound
Extras
I guess people really like to watch robots breaking stuff. Transformers: Age of Extinction was another worldwide hit for the franchise, repeating more of the same paranoid nonsense (and lame dialogue and unfunny jokes) as its three predecessors. This time, a couple of suits decide they can build and control their own Transformers, using technology stolen from the evil Decepticons. How do you think that works out? The human ally this time is an underdog inventor (Mark Wahlberg) with a cutie-patootie daughter, in a mildly disturbing riff on Beauty and the Beast.

Will the DVD Format Disappear?

Got a tech question for Sound & Vision? Email us at AskSandV@gmail.com

Q Some of my friends argue that spending extra money on Blu-ray Discs is unreasonable since DVDs offer almost equal picture quality for less money. Worldwide, DVDs sell much better than Blu-rays, which many people still consider to be a format for videophiles. Do you think it’s possible that DVDs will ever disappear from the market? —Tomek Ciecwierz, Warsaw, Poland

In Space, No One Can Hear You Scream "Atmos!"

You remember Gravity, right? Outer space, pulverized space ships, Sandra Bullock floating weightlessly, heavy breathing—pretty good film from both a technical and narrative standpoint. You might already have a copy on Blu-ray. But I'd like to give you two reasons to consider buying it again. A new "Diamond Luxe Edition" Blu-ray due in February promises to be very interesting for both film aficionados and home-theater enthusiasts. Doubly interesting if you are both.

Direct or Dipolar Speakers for Dolby Atmos?

Got a tech question for Sound & Vision? Email us at AskSandV@gmail.com

Q I am building out a dedicated 7.2-channel home theater and was planning on buying dipolar surround speakers to help “spray” sound along the side and back walls. After reading a few articles on Dolby Atmos, however, it seems that direct-radiating speakers would be the more appropriate option since they can better pinpoint objects in the room. Am I correct in thinking that direct-radiating speakers would serve better in an Atmos environment, or do I have things totally wrong? —Adam Tremai / via e-mail
