My editor has insisted that I am unable to name Atmos in a automotive “Catmos.” So anyway, Catmos is the most recent implementation of Dolby’s object-based encompass know-how. We have talked earlier than about how nicely it might add peak to film sound in theaters, how most mid- and high-end soundbars have some Atmos performance and the way even some headphones have it in-built. However in a automotive?
Effectively, sure truly. Today the automotive is the place most individuals take heed to essentially the most music. In some methods it is also an ideal place to convincingly create encompass audio, for the reason that listening positions are fastened, and a system is designed to include and compensate for precisely the place the audio system are positioned. Neither of these issues are attainable at residence, and even in a theater it isn’t as targeted.
One of many largest points with most automotive audio constancy is ambient noise. One technique to drastically cut back that situation is by eradicating the engine utterly. A high-end electrical car makes for a best-case state of affairs in a cellular encompass sound system, and to that finish I used to be invited by Rivian and Dolby to listen to their almost 1,000-watt, 18-driver Atmos-enabled system within the R1S SUV at an occasion in Venice, California, conveniently 15 miles from the place I reside. It is LA, so simply shy of two hours later, I used to be all ears.
Atmos-to-Go
With Atmos (on the fitting), sound designers can pinpoint precisely the place in a theater, any Atmos theater, they need a sound to “seem.” This contains overhead, or actually, nearly anyplace in the whole house of the cinema.
Let’s again up a second and discuss Atmos. It is an interesting know-how, and its “object-based” strategy gives a distinct technique to combine motion pictures and music. The standard method of audio mixing, which has been round for many years, was to assign a sound or instrument to considered one of 5 encompass channels or the subwoofer — often known as 5.1. Three up entrance, two within the again or sides. Some motion pictures had much more channels, with seven channels changing into pretty frequent, permitting for aspect and rear channels.
Atmos adjustments all that up with the power to deal with a sound or instrument as an “object.” Within the mixing course of, the sound designer can transfer that object wherever, and the Atmos encoder would perceive the place in bodily house the sound designer meant. An Atmos decoder, in a theater, say, creates a digital map of the system’s audio system and may translate “door creak in again left nook” so the viewers hears it come from that place. This accuracy was tough, if not unattainable, earlier than Atmos. A designer might wish to place a sound in a particular location, however there’d be no technique to regulate what that meant in a theater with 5 seats, 50 or 500.
The Rivian R1S SUV.
Because of this extra exact method of transferring sounds round, peak audio system had been far simpler to make use of. Now sounds might extra convincingly go from behind the display screen, up over your head, and “land” someplace behind you. Finished proper, it is extraordinarily immersive. If a theater did not have peak audio system on the ceiling, the Atmos would nonetheless work, with the decoder shunting the sounds off to the edges. So it might nonetheless whoosh previous you, simply not as convincingly as it might have in a extra elaborate system. The Atmos decoding course of is “good,” primarily understanding what the audio system and house had been, and adjusting so it might do the most effective it might with what it had.
Constructed on the identical platform and sharing a majority of components, the R1T is mainly the identical because the R1S minus a roof over the rear. It loses 2 audio system within the audio system too.
The double-edged sword on this case is that Atmos can work, at some degree anyway, with far much less elaborate methods. That is why there are single-unit soundbars and even TVs with “Atmos.” They’ve upward-firing audio system at finest — and, extra usually, in depth processing to simulate that peak sound with various ranges of success.
Which brings us again to Atmos within the automotive. The listeners are all in recognized locations, there will be peak audio system, and it is easy to have rear audio system since all trendy vehicles — particularly SUVs — are auditorium-sized anyway.
Rivian Premium Audio with Dolby Atmos
The motive force areas within the Rivian R1S. The woofers are positioned within the doorways, the tweeters on the pillars and above. The subwoofer is within the trunk, above and behind the fitting rear wheel.
The 2025 R1S Gen 2 I noticed boasted a Dolby Atmos system with 18 drivers, which had been powered by 960 watts of amplification. Placement for many of those audio system was pretty typical, with some within the sprint, together with a middle channel within the center, woofers within the doorways and a subwoofer within the trunk.
What’s much less frequent is the tweeters on the roofline, above the doorways however under the glass roof. The R1S is a large car, so that they may very well be thought of peak audio system for just about everybody, and in the event you’re tall sufficient that these are ear degree, you would not have the ability to see out the windshield.
Like most electrical autos, the R1S has few knobs or dials. Nearly every thing is managed by way of a touchscreen.
You want Atmos-encoded content material to get an actual Atmos expertise. To that finish, the in-car leisure system has built-in Apple Music, Tidal, Amazon Music and Audible. Throughout my demo, we listened to a number of tracks, together with Ariana Grande’s 7 Rings and As It Was by Harry Kinds.
The monitor that took full benefit of Atmos was Pink Floyd’s Cash: The long-lasting money register opening distinctly began someplace behind the rear passenger-side door, then progressed to above the dashboard, then working its method across the inside. The precise devices then crammed the house in a method that conventional stereo would have struggled with (this Atmos combine was painstakingly permitted by the band). I am unable to absolutely decide the sound high quality based mostly on a demo of pre-chosen music, however total the treble was clear and the bass punchy, particularly with the Kinds monitor.
One of many peak audio system, observe its location close to the seize deal with. The “sky” on this picture is actually the sky, as seen by way of the panoramic roof.
Whereas there are points of a automotive which might be good for encompass sound, and others that are not. I discussed above about highway noise. Provided that the R1S is electrical, I assume highway noise is lower than, say, my Miata. The opposite is each a constructive and a unfavorable. On one hand, engineers know precisely the place the potential listeners are and, roughly, what number of. The truth that they’re unfold aside, near the “partitions,” and to not point out extensively completely different distances to the audio system, all add a not insignificant problem. The combination within the R1S is biased towards the motive force and entrance passenger, which is not too shocking since you may all the time have no less than a kind of. Rear listeners will nonetheless get the impact, there are peak audio system again there too, however to a lesser extent. A budget seats, if you’ll.
Drivers within the A-pillar and sprint.
Primarily based on my three-song demo, I am unable to say the place the Rivian’s system stacks among the many high-end automotive audio methods I’ve heard (which is kind of just a few). Nonetheless, I can say the encompass facet was pronounced and extra natural-sounding than something I’ve heard earlier than. So, maybe unexpectedly for some, it was one of many higher demos of Atmos I’ve heard exterior a theater.
The settings display screen. I did not have an opportunity to mess with the sound throughout my demo.
They hear me rollin’, they curious
Rivian is not the one firm together with in-car leisure with Dolby. There are additionally Atmos methods put in in, or deliberate for, fashions by Cadillac, Lotus, Lucid and Chinese language automaker Li. One apparent development amongst all of these is that Dolby Atmos does not come low cost. Rivian’s R1S car is within the “premium SUV” class and may simply value over $100,000 (which is, in equity, what most of those large electrical vans value). The Premium Audio system is mixed with the glass roof as a part of the $2,500 Sound + Imaginative and prescient package deal. You want a subscription to one of many aforementioned streaming companies and Rivian Join Plus, which prices $15 a month or $150 a 12 months. This additionally features a knowledge connection and may flip your R1S right into a hotspot, in addition to another options. For such a complicated car, it is disappointing that there isn’t any Apple CarPlay or Android Auto.
Again seat (or, technically, center row), listeners can have some management over what the pilot and co-pilot are listening to.
So is it price it? I solely had a quick demo, in a stationary automotive. I am additionally too low cost, to not point out being a broke author (purchase my ebook!), to spend round $100K on a car, however $2,500 for some nice sounding audio, to not point out a glass roof I am unable to think about not having in a truck like this, looks like an affordable add-on for ~2.5% of the full worth. So, in all probability?
Will we see Atmos in lower-end autos? Maybe. Automotive firms have been partnering with audio firms for a very long time, and whereas as of late it is normally Bose or some taste of Harman, automakers know there is a revenue alternative in higher sound. Will they pay for the additional engineering and tuning to get Atmos working accurately? And even simply working? The upper-end manufacturers may, however it’s extremely unlikely we’ll see an Atmos system with peak audio system in one thing like a Nissan Versa.
Then once more, if there is a demand, who is aware of. I am positive there’s some exec on the market who loves Atmos and needs to place it in a extra budget-friendly automotive. Type of a contemporary Pontiac GTO — besides as a substitute of an enormous V8, it has Catmos. [You’re fired. —Ty]
