Immersive audio isn’t a gimmick. I installed an immersive audio setupalmost two years ago. Now that I’ve lived with it, written about some of my immersive audio listening impressions, and tested immersive audio-based gear (like Denon's X7200WA and Anthem's AVM 60), I can attest that immersive audio truly is the next evolution in home theater—and it’s here today.

While Dolby Atmos and DTS:X have had the lion’s share of press in the United States, Auro-3D has often been forgotten in the discussion. But thanks to a few AVR manufacturers, Auro-3D has been making some quiet inroads. In this article, we’ll talk a bit more about Auro-3D, the company's technology, how you can take advantage of it at home, and how it performs in a real-world setup.

Auro-3D's History

Auro-3D’s introduction harkens back to the 2006 AES convention in Paris and San Francisco where inventor Wilfred Van Baelen demonstrated Auro 9.1 and Auro 10.1 layouts. By 2011, Skywalker Sound had installed the first Auro-3D studio system in their Mix A Studios. With the help of Barco, best known for their cinema projectors, Auro-3D became a reality in commercial theaters. And, on November 1, 2011, George Lucas’ Red Tails became the first film in history released with immersive sound as an Auro-3D 11.1 mix. In case you're keeping score, Dolby wouldn’t come to theaters with Atmos until the following year when Disney-Pixar’s Brave became the first film released in Dolby Atmos.

Fast forward to today, and there are lots of Auro-3D enabled theaters around the world. To find an Auro-3D enabled theater near you, see: Barco’s Auro-3D theater finder here.

Auro-3D is a Hybrid Technology with Channel and Object-Based Options

Most people don't know that Auro-3D is a hybrid format that consists of both a channel-based and object-based technology. With channel-based audio, engineers mix sounds into specific channels. DVDs and Blu-ray movies played back on traditional home theaters sporting stereo, 5.1, or 7.1 configurations have all been channel-based. Auro-3D’s consumer solution remains a channel-based approach.

Object-based audio takes a different approach. Object-based audio works by mixing sounds as individual objects in a particular space and time as opposed to a specific channel. With object-based audio technologies, you set up your speakers according to one of several speaker layout options that your AVR offers. The AVR's processor then maps and mixes the sound into the appropriate speakers (based on which speaker layout you have) to make it sound as though the sound is coming from the appropriate coordinates. Dolby Atmos and DTS:X are object-based audio technologies.

Regarding speaker layouts, Dolby Atmos and Auro-3D require specific speaker layouts. DTS:X can adopt either layout.

Because Auro-3D is a hybrid format, the company brands its object-based technology as AuroMax to avoid any confusion. Most AuroMax installations require more than 20 speakers. Thus, they are confined to theater installations. There aren’t any consumer-grade AVRs on the market today that support AuroMax. We’ll therefore be confining our discussions to Auro-3D’s channel-based, consumer-focused technology in our overview.

Auro-3D's ideal speaker layout places the height layer speakers at a 30-degree angle and a 90-degree, face-on position to the listeners for discrete height effects

Upmixing Traditional Mixes to Immersive Audio

In addition to native immersive audio content, Auro-3D also includes an up-mixer, which it calls Auro-Matic 3D. Auro-Matic 3D will take standard 5.1 or 7.1 mixes and render them as immersive audio mixes by extracting height and ambient sound information. You can also apply Auro-Matic 3D on stereo sources though I'm not a fan of that personally. To my ears, it just doesn't sound right. Sometimes you can have too much of a good thing but I do encourage you to try it out. It's always good to have more tools in your bag of tricks.

On my Denon X7200WA I have the ability to fine-tune the performance of the Auro-Matic 3D upmixer. The small setting is ideal for pop, chamber music or movies with lots of dialog; medium, the default, is best for jazz, typical movies and TV; large is ideal for orchestral works and action movies; and speech is designed for dialog broadcasts, like news programs. In addition to these presets, you can also fine-tune the level of the up-mixed channels used. You can set a value from 1 to 16, where 1 is no upmixing and 16 is the maximum effect. The default on the Denon X7200WA is 10.

Auro-3D’s Channel Naming Convention

Auro-3D setups follow the typical naming convention for home theater where the first number refers to the total number of channels (including height) and the number after the period corresponds to the number of subwoofers. Dolby Atmos and DTS:X, in contrast, put the number of floor standing speakers first, the number of subwoofers second, and the number of height channels third, with each series of numbers separated by periods. Therefore a 9.1 Auro-3D setup corresponds to the same number of channels as a 5.1.4 Dolby Atmos or DTS:X setup. Got it?

Because consumer-based AVRs don’t support more than five floor-level channels when using Auro-3D, think of Auro-3D as an extension of the 5.1 surround format. Any number above five corresponds to height channels. Height channels sit above the left and right front speakers and above the left and right surround speakers. Therefore, a 9.1 Auro-3D setup means five floor-standing speakers and four height speakers. A 10.1 Auro-3D setup adds the voice of God in-ceiling speaker above the listening position. While there are native Auro-3D mixes above 10.1, today’s consumer-level AVRs with Auro-3D don’t support the additional channels natively so they will be down-mixed.

In this graphic, you'll find the different Auro-3D configurations and the speakers that correspond with each

What Makes Auro-3D Different?

Auro-3D’s speaker layouts consist of three distinct audio layers. You have a traditional floor-level speaker arrangement, a height layer, and finally an overhead or top layer. As I mentioned, the height layer speakers are located above their respective floor-standing speakers.

Auro-3D calls for an overhead speaker for a third, top layer, which is unique to the Auro-3D format. The third speaker is commonly called the 'Voice of God' channel because it reproduces sounds from above. While DTS:X can theoretically support the top speaker among its speaker layout agnostic architecture I'm not aware of any consumer-based AVR that allows you to use it with DTS:X. I can't use the top speaker on the Denon AVR-X7200WA with DTS:X content. Therefore, for purposes of our discussion, we'll consider the third layer—the overhead layer—unique to Auro-3D in today’s consumer AVR electronics.

Auro-3D has three layers, which makes it different from other immersive audio formats, which only have two layers

Auro-3D Native Content

While it’s easy and natural to focus on the technical merits of a particular technology, at the end of the day it’s all about the content, isn’t it? And available content makes Auro-3D unique. Unlike DTS:X and Dolby Atmos, there are a number of multichannel music Blu-rays that take advantage of Auro-3D. Auro-3D keeps a current listing of movies and music here.

If you’re the type of person who dismisses multi-channel music, let me simply say that if you had bad experiences with some of the old multi-channel DVD-audio discs, you're going to be pleasantly surprised with Auro-3D material. The material I listened to was nothing short of breathtaking. Auro-3D mixes were typically used to convey the immense space of a venue, expand the soundstage, and create a more “you are there” feeling.

Auro-3D's top layer is like adding a center channel for overhead effects as opposed to creating a phantom center channel from left and right height channels

The European and Asian markets seem to have a number of movie and music Blu-rays mixed in Auro-3D. However, trying to get any of those titles in the United States is a bit more challenging. I could find some titles on Amazon Germany but not on Amazon in the US. For US-based customers, if you encounter a dearth of content, you’ll look to take advantage of Auro-3D’s Auro-Matic 3D upmixer, which is excellent.

How can I get Auro-3D?

In addition to a compatible speaker layout, you need an AVR or pre-pro capable of decoding Auro-3D. Marantz and Denon (both subsidiaries of D+M Holdings) were the first mainstream AVR manufacturers to support Auro-3D with an optional $199 upgrade. In September of this year, those two brands announced that going forward Auro-3D will now be an out of the box feature for several of AVR models. That's a huge step forward!

Denon's X7200WA receiver confirmed an Auro-3D signal on its front display along with the active channels

Unfortunately other than Marantz and Denon, other consumer-focused AVR manufacturers haven’t jumped on board the Auro-3D bandwagon. Of course, there are Auro-3D offerings in high-end processing solutions like Storm Audio's immersive audio processors and amplifiers that will put you back $16,000 or more. When I’ve asked other companies about supporting Auro-3D, they have been a bit gun shy, telling me that they are taking a wait and see approach to the immersive audio market.

If you want to take advantage of Auro-3D in a typical home or home theater, you’ll want to look at supporting models from Denon or Marantz. And let’s call a spade a spade: if you’re left with only those two brands as choices, it doesn’t get much better than that.

Can I support Auro-3D with DTS:X and Dolby Atmos?

If you configure your AVR to use Auro-3D, you can also playback native DTS:X material. Auro-3D actually sits on top of a DTS audio layer. DTS:X will support Auro-3D’s speaker layout so that you can run both concurrently. You cannot, however, use Dolby Atmos in that case. Auro-3D and Dolby Atmos layouts are incompatible. That's a huge pain in the neck, but it doesn't mean you're stuck.

If you want to support Auro-3D, DTS:X, and Dolby Atmos content at the same time, you’ll need to arrange your home theater with the so-called “unified speaker layout” where you have two front height and two rear height channels. To take advantage of the overhead, voice of God speaker with the unified speaker layout you must use the 11.1 amp assign speaker layout.

I have tested the “unified speaker layout” with Auro-3D material in my setup. In my room, I prefer a proper Auro-3D layout with side height surround speakers and, of course, the overhead voice of God speaker. To me, the immersive experience is better. Gene DellaSala, Audioholics president, did an extensive analysis on universal layouts for immersive audio formats that you should check out if you want to read more on this topic.

With Auro-3D mixed content, height effects are more pronounced and seamless coming from the side. Oh and in case I didn't emphasize it the first time: There’s just no substitute for the overhead speaker.

The table above shows the typical Auro-3D speaker positions and angles for each speaker assuming you could take advantage of a full Auro-3D setup, which today's consumer AVR's cannot.

Installing Auro-3D in Your Home

Auro-3D offers an installation guide in PDF that you can access here. The guide covers the history of Auro-3D, the different speaker configurations, rooms, and special cases such as low ceilings or multiple theater rows that require multiple height speakers.

For most users, you'll likely be concerned about supporting all immersive audio formats—including Dolby Atmos and DTS:X. Therefore, what do you do? The most logical installation recommendation is to install an Auro 10.1 or 13.1 format (assuming you have the space and can install the top speaker). In the case of a 10.1 installation, install speakers at the front and rear of your room. The reasoning here is that currently, we know that the unified format accommodates front and rear height speakers. It also provides you with the most future-proof scenario. If you install a 13.1 then you can anticipate future immersive audio advancements, but know that the side surround speakers may not be active. You can also run a canonical Auro-3D setup should you want to.

My biggest beef with my Denon AVR-X7200WA receiver is that I can't use the amp assign mode to run independent Auro-3D and Dolby Atmos and DTS:X setups. I should be able to do that. I can load the different speaker configurations with Audyssey calibration, but it takes almost 15-20 minutes to re-upload them, which is a pain. My wish is that AVR manufacturers would allow users to run parallel and native Auro-3D and Dolby Atmos setups. DTS:X can sit on either. I don't know what's involved to do this from a programming point of view, but I can't imagine it's hard to do.

It's worth mentioning that you cannot use Dolby Atmos-enabled speakers with Auro-3D. Atmos-enabled speakers fire sounds up towards the ceiling and then bounce them back down to the listening position. These type of speakers are NOT nearly as effective as discrete mounted speakers and only recommend them as a last resort.

For more information, see: Dolby Atmos-enabled vs Discrete In-Ceiling Speaker Listening Test Results

You need discrete on-wall or in-ceiling speakers with Auro-3D. In case you're wondering, I did not try Atmos-enabled speakers to see how they sounded with Auro-3D.

Auro-3D 10.1 Test Setup

The speaker configuration in my home theater is designed to support a canonical 13.1 Auro-3D setup. While the Auro-3D specification prefers direct-radiating speakers, I did not follow that setup. Instead, I have all in-ceiling speakers.

Unlike Dolby Atmos, which calls for traditional, down-firing, in-ceiling speakers, Auro-3D calls for models with angled drivers for the front height and surround height speakers. The sole exception is the top voice of God speaker, which should not be angled. In my setup, I followed Auro-3D’s canonical recommendations where the Beale Street in-ceiling height speakers use angled tweeters and the voice of God overhead speaker has a down-firing tweeter.

The Beale Street Audio speakers used for the Auro-3D height channels have angled woofers and pivoting tweeters.
