NIO ET7 audio system reveals how important software will be in future vehicles [Editorial]

Published

on

NIO went the extra mile—and then some—when it conceptualized the audio system for the ET7. The NIO ET7 has 23 speakers powered by Swedish digital audio pioneer Dirac’s Opteo Professional audio software and Dolby Atmos technology. 

NIO and Dirac’s work on the ET7’s audio system reveals the changing design of the car’s cabin and the role software plays in its redesign.

The NIO ET7’s Sound

Every automaker has a specific sound they would like their passengers to enjoy in their vehicles. NIO also has a particular sound target, and for the ET7, the Chinese automaker wanted it to come through crystal clear. 

NIO worked closely with Dirac to create its sound. The NIO ET7’s official online page states that the four-seater car has 23 speakers, four overhead speakers, and a subwoofer. It also has a 20-channel amplifier and comes standard with Dolby Atmos Technology. 

NIO didn’t just add lots of speakers to the ET7, though. The China-based automaker together with Dirac were meticulous and intentional with the ET7’s audio system.

Redefining the Cabin

Audio experts must consider the environment the sound will be played in, making it challenging to work with vehicles. Lars Carlsson, the Head of Business Development Automotive Audio and Vice President at Dirac, told Teslarati that audio experts have to consider many things when creating the perfect sound inside a vehicle. They have to consider the number and position of the speakers and the number of seats in the vehicle. Audio experts must also consider how sound reflects on the cabin’s different surfaces and windows. 

Each speaker output in the NIO ET7 was measured with 16 microphones, positioned in each seat for a total of 64 measurement positions in the cabin. The measured data gave Dirac a good overview of the acoustic performance of the car’s cabin and creates the base for Dirac’s patented algorithms to optimize the sound.

“We base everything on measurements and data. Our process really saves audio engineers a lot of time. They can tune on their computer instead of spending weeks in the car,” Carlsson said. 

After measuring the cabin, Dirac used algorithms to “derive the optimum solution” for its sound field control technology. With sound field control, Dirac created “super speakers” for the ET7. Typically, there are three speakers in a car door: low frequency, mid-range frequency, and a tweeter for the high frequency. Dirac uses sound field control to digitally align the speakers, making them collaborate to realize one full, quality sound. 

“In addition our algorithm lets the speakers in the cabin and the subwoofer collaborate to create an even sound field in the car, which means we can actually create an equal audio experience in every seat. You get the voice right in front of you and a good imaging and a very even bass distribution and tight bass,” explained Carlsson.

Software’s Critical Role in Future Vehicles

Software is playing an increasingly important role in the auto industry as automotive OEMs and startups reconceptualize the idea of the vehicle. Now, automakers are reimagining the use of the car cabin as more vehicles integrate autonomous software. 

Software lies at the center of redesigning the cabin space for passenger activities. Many automakers have started investing in software for their vehicles. For instance, Volkswagen invested €2 billion in a joint venture with China-based Horizon Robotics. And Stellantis launched a software development center in India recently. 

Audio, in particular, is beginning to play a more significant role in the cabin as automakers introduce more types of media for passengers to enjoy while on the road. Electric cars coming out on the market have fun new features now, like karaoke, videos, games, and more which rely heavily on audio systems. However, it is autonomy that drives the cabin’s redesign.

“We have an enormous interest for our solutions because audio is getting more and more important in the car. This is true for electric cars because it’s a quieter environment but also when looking into autonomous cars, where maybe you’ll be working in your car, you’ll be listening to music, you’ll be watching videos, you’ll have maybe rotating seats,” said Carlsson. 

“There’s a lot of challenges also coming ahead, but I would say that Dirac is very well equipped for future challenges because software for anything in the cars is key,” he added.

Tesla Cybercab sightings on public roads are becoming much more frequent, and they all are pointing to one thing: imminent production.

The Tesla Cybercab is the company’s vehicle developed for fully autonomous travel, as it will be manufactured without a steering wheel or pedals, according to CEO Elon Musk.

Tesla Robotaxi Cybercab: Seats, price, special features, release date, and more

After it was unveiled a year ago by Tesla, the company has made some pretty drastic jumps in progress in terms of the Cybercab, but a recent development has truly pushed fans of the company to think it is probably going to be available soon.

Last week, we reported on the first Cybercab sighting when the vehicle was finally being tested on public roads. The spotting was not a one-time deal, as we are now seeing many more sightings on public roads:

The first spotting was in Palo Alto, just a few blocks from Tesla’s Engineering Headquarters in Los Altos. This second sighting appears to be relatively close to that first spotting, and it seems unlikely Tesla would be putting it on roads much further than that.

The public on-road testing of the Cybercab marks a major milestone in the entire project for Tesla. These early sightings and testing phases are usually followed by a lot of speculation about when the vehicle could end up in the hands of customers.

However, Tesla has already put a definitive date on when Cybercab production will begin, as Elon Musk said during the Q3 Earnings Call that it would roll off production lines in Q2 of next year.

But the speculation regarding the Cybercab is slightly different than other vehicles because Tesla has been developing it for fully autonomous travel; it’s not meant to be driven by humans but instead by software and the company’s Full Self-Driving suite.

Despite the vehicle being spotted with a steering wheel and pedals in the recent sightings, Musk has maintained that the Cybercab will not be developed with typical controls for a human. He recently confirmed this, and it does not seem the company is willing to veer too much from its plans for an autonomous car.

Tesla has rapidly progressed in the production of its most anticipated Model Y trim level: the Model Y Performance.

New drone images from noted drone operator and Gigafactory Texas observer Joe Tegtmeyer show Tesla is moving forward quickly in terms of its progress in producing the new Model Y Performance.

The vehicle is being spotted more frequently at the factory located just outside of Austin, with what appears to be the first units rolling out to outbound lots:

In the United States, Tesla unveiled the Model Y Performance on September 30, the newest iteration of the fastest trim level of the best-selling car in the world for the past two years. It was launched on the very last day of the $7,500 electric vehicle tax credit in the United States.

It featured a handful of performance improvements, including a 0-60 MPH acceleration rate of 3.3 seconds, a trim from the 3.5 seconds the 2025 version offered.

Additionally, the range has gone from 277 miles to 308 miles, a notable improvement in terms of how far it can travel on a charge.

There are also a handful of hardware changes that Tesla made to improve its aerodynamic performance, which all likely can be attributed to the boost in speed and acceleration, as well as range.

The vehicle was initially launched in Europe, which was not surprising, especially as Tesla was testing the new Performance trim at the famed Nurburgring in Germany.

Deliveries are currently slated for late November, but some orders are getting projections of mid-December for their Model Y Performance, which would help Tesla bolster its end-of-year delivery figures and follow up on an extremely bullish finish to Q3, which was the company’s strongest performance in history.

Twitter co-founder and Square CEO Jack Dorsey has publicly backed Elon Musk’s leadership ahead of Tesla’s pivotal shareholder vote, which is expected to be decided later today at the company’s 2025 annual meeting. 

Dorsey framed the pay package as an engineering and governance crossroads for Tesla.

Dorsey’s public nod framed as an engineering defense of Musk

In a post on X, Dorsey weighed in on Tesla’s post about being in a “critical inflection point.” As per the Twitter-co-founder, the vote on Musk’s 2025 performance award is not about compensation. Instead, it’s about ensuring the path for the company’s engineering in the coming years. 

“This is not about compensation. it’s about ensuring a principled (and exciting!) engineering approach to the company’s future,” Dorsey wrote on his post, later stating that users of Cash app with TSLA shares would be able to vote for the CEO’s proposed 2025 performance award. 

Elon Musk appreciated Dorsey’s endorsement, responding to the Twitter co-founder’s post with a heart emoji. Musk has been pretty thankful for the support for is fellow tech executives, also thanking Michael Dell recently, who also advocated for its proposed 2025 performance award.

Musk’s support

While Elon Musk’s 2025 performance award has received opposition from proxy advisors such as Glass Lewis and ISS, it has received quite a lot of support from longtime bulls such as ARK Invest, and, more recently, Schwab Asset Management following calls from TSLA retail shareholders. 

“Schwab Asset Management’s approach to voting on proxy matters is thorough and deliberate. We utilize a structured process that focuses on protecting and promoting shareholder value. We apply our own internal guidelines and do not rely on recommendations from Glass Lewis or ISS. In accordance with this process, Schwab Asset Management intends to vote in favor of the 2025 CEO performance award proposal. We firmly believe that supporting this proposal aligns both management and shareholder interests, ensuring the best outcome for all parties involved,” Charles Schwab told Teslarati.
