Tesla’s Impressive Sound Systems Are Missing One Thing: True Spatial Audio [Opinion]
Tesla has consistently demonstrated a commitment to high-quality audio hardware in its vehicles. The sound engineers go through a thorough design process - including integrating the subwoofer’s sound flow through the Cybertruck’s hollow body sections. Tesla offers, by and far, one of the best OEM audio experiences in its price range.
However, physical components and engineering magic aside, the current software that drives Tesla’s audio experience is sub-par when compared to higher-end audio systems on the market. It falls short of delivering truly spatial, three-dimensional audio that many audiophiles and even discerning casual listeners have come to appreciate from the likes of $100 earbuds with spatial audio support from their cell phones.
This really feels like a missed opportunity, especially when Tesla used to offer “Dolby Surround” in the past.
Immersive Sound… Kind Of
Tesla’s proprietary Immersive Sound option widens the sound stage by creating a surround-sound-like effect within the vehicle. It has evolved over the years from a simple “Off/Standard/High” to include slightly more granular control, as well as an Auto mode that intelligently adjusts the level of immersion based on the content being played.
For many, including myself, the experience often feels more like an improved stereo field rather than a genuine multi-dimensional soundscape. Even when set to High and paired with Hi-Fi downloaded music from sources like TIDAL, Immersive Sound struggles to open up the sound stage. The sense of height and precise placement of individual sound sources - hallmarks of spatial audio - are missing, leading to an audio presentation that, while clear and powerful, ultimately feels a little flat.
In reality, Immersive Sound often just turns on the A-pillar speakers and uses them for a wider set of sounds than they are normally used for, which really feels rather disappointing.
A good example is Imagine Dragons’ song Believer. Try listening to it with Immersive Sound on, and then off. If you’ve got headphones with Spatial Sound / Dolby Atmos support, try listening to the same song there. You’ll find a world of difference.
The Gold Standard: Dolby Atmos
Technology like Dolby Atmos has become the gold standard for listening to spatial audio - and represents a substantial step above traditional “Surround Sound” and Tesla’s current Immersive Sound. Dolby Atmos does a lot to achieve that truly three-dimensional audio experience.
They use object-based audio, where sounds are treated as individual objects that can be placed and moved precisely in a 3D space rather than being confined to specific channels, like with 5.1 or 7.1 Surround Sound. They also include a vertical dimension, making the sound feel like it’s coming from above, below, or all around. This is done through dedicated processing (and sometimes dedicated down-facing speakers) to render the sound in a fully 3D space.
All that, alongside the ability to render complex mixes like 5.1 and 7.1 surround sound with exceptional clarity, means that individual instruments and vocal layers maintain their distinction.
The overall result is a refined listening experience that is genuine, more engaging, and compelling. It isn’t just better for music too - it makes video content consumption better with spatial sound matching what’s being displayed on-screen.
Amazing Hardware Deserves Amazing Software
Tesla’s investment in custom-engineered audio systems is commendable. The 17 speakers in the Cybertruck represent one of the best OEM-designed speaker arrays capable of producing detailed and dynamic sound.
However, this amazing hardware is being asked to perform an orchestra with one hand tied behind its back. Without the extra spatial rendering capabilities of an industry standard like Dolby Atmos, we may as well only have five speakers. Tesla isn’t taking full advantage of the great hardware in these vehicles by letting the software lag behind.
Implementation
The barrier to entry for true surround sound may not be as high as some imagine; for perspective, a consumer license for Dolby Atmos on a PC is remarkably affordable - only $14.99. While commercial automotive licensing is on a different scale, this illustrates that access to the core technology isn't inherently prohibitive, suggesting it's more a matter of prioritization for Tesla.
Some might perceive the engineering effort to implement and tune true spatial audio as immense, but it's worth noting that advancements in calibration are constantly being made. For example, in a controlled home environment, initial spatial sound system tuning can sometimes be accomplished in as little as an hour.
Naturally, the acoustic complexity and variability of a car interior demand a more involved process, but for a company with Tesla's engineering prowess, creating an exceptional in-car spatial audio experience is well within reach and arguably less of a monumental task than many might think.
This isn’t just about satisfying those with a particular ear for sound - a truly exceptional spatial sound system like Atmos, or at least a functional in-house one that genuinely matches its capabilities, would be a huge bonus for Tesla’s flagship vehicles. It would help to elevate the experience, especially as Tesla continues to narrow the premium feel between their flagship vehicles and their everyday vehicles.
Tesla builds vehicles with some of the most impressive audio hardware on the market, so there’s no reason not to match this with the most impressive audio software. Let’s bring back Dolby surround sound support.
