Upmixing with Dolby Atmos


Dolby Atmos is now. Not years from now. Right now.

While the stream of programming with Dolby® Atmos has only begun to fill the media landscape, you don’t have to wait to experience the the immersive, cinematic sound of Dolby Atmos thanks to “upmixing.”

You will immediately notice the benefits of upmixing compared to standard surround sound during movies as well as musical performances, video games and sporting events.

We’ve said it before and we’ll say it again. Dolby Atmos is the biggest advancement in home and cinema audio since surround sound. (Overview + FAQ of Dolby Atmos.)

HOW DOES UPMIXING WORK?

A Dolby Atmos enabled receiver will handle most of the work by recognizing the sound that would typically be sent to the surround channels and sends some of that sound out to the Dolby Atmos elevation channels.

In Dolby’s own words: “The Dolby surround upmixer employs the original soundtrack to create a highly accurate rendering of the environment in the movie while simultaneously honoring and maintaining the artists’ intent for the mix.”

All of the major receiver manufacturers including Onkyo, Denon, Marantz, Yamaha, and Pioneer are making Dolby Atmos enabled receivers that will work with Klipsch Reference Premiere Dolby Atmos enabled speakers.

THE DIFFERENCE BETWEEN SURROUND SOUND AND UPMIXED DOLBY ATMOS

Upmixing allows you to hear height/elevation effects, creating a much more immersive, true-to-life experience versus traditional surround sound. This isn’t a gimmick. It’s a honest-to-goodness improvement that will reinvigorate your existing movie collection, television programs, video games and music collection.

Dolby says “Unlike previous wideband upmixing technologies, the Dolby surround upmixer operates on multiple perceptually spaced frequency bands for a fine-grained analysis of the source signal. The Dolby surround upmixer can individually steer frequency bands, producing surround sound with precisely located audio elements and a spacious ambience.”

Don’t believe it? We strongly recommend a visit to your local Klipsch dealer who carries Dolby Atmos speakers to test this out for yourself.

THE DIFFERENCE BETWEEN UPMIXING AND “PURE” DOLBY ATMOS

“Pure" Dolby Atmos is only possible when source material is encoded (mixed and published) in Dolby Atmos technology. If you are looking at a Blu-Ray, it should be clearly labeled with the Dolby Atmos logo on the disc packaging.

With a “pure” Dolby Atmos mix, you are hearing sound exactly as the (human) sound editor intended it. In order to upmix to Dolby Atmos, an algorithm in the receiver determines which sounds go to the Dolby Atmos channels based on frequency and phase correlation. Essentially, upmixing is a synthesized, yet very effective Dolby Atmos experience that draws from the original 5.1/7.1 mix.

More and more content is being created in Dolby Atmos; however, you will be delighted by the immediate benefits that you will hear by upgrading to a Dolby Atmos setup.
