Dirac and NIO collaborate to push the boundary of automotive audio with the new NIO ET7 smart electric flagship sedan

August 16, 2022

Dirac and NIO collaborated to bring Dirac’s top-of-the-line automotive sound solution to the ET7, delivering unparalleled sound performance that reproduces any immersive content faithfully, bringing the in-car audio experience beyond users’ expectation.

UPPSALA, Sweden, August 16 — Swedish digital audio pioneer Dirac and electric automobile innovator NIO today announced collaboration on the NIO ET7 sound system. The NIO ET7 has adopted Dirac Opteo™ Professional, the company’s most advanced automotive sound optimization solution, to ensure the ultimate sound performance.

The NIO ET7 features standard configuration of 23 speakers and 20*1000W amplifier output channels. Its four main channels are composed of high, middle, and bass speakers in three units, with a subwoofer and four overhead channel speakers. Panoramic acoustic music with outstanding details and clarity, combined with Dirac Opteo Professional, renders the most realistic, clear and immersive sound experience through the ET7’s 23 high-quality speakers.

“At NIO, we wanted to deliver the ultimate immersive sound experience in the ET7 – so that passengers across all seats can listen to music as if they were in a concert hall,” said Danilo Teobaldi, NIO Engineers Vice President. “As we knew doing so required more than enabling immersive content, we built the best possible sound system for the ET7, then turned to Dirac and its industry-leading digital optimization to take the performance to an even higher level. Our collaboration with Dirac helped us ensure that our users could experience the best automotive sound system on the market.”

Achieving peak sound performance in cars takes ingenuity and expertise. The car cabin is regarded as one of the most challenging acoustic environments in the world – as in-car speakers cannot perform as intended regardless of their price-point and design.

Within the cabin, speakers can’t be positioned as optimally as they would, for example, in a home theater. As a result, speakers interfere with each other, causing distortion and reducing audio clarity. The interference increases when more speakers are used. In addition, the car cabin itself adds unwanted sound coloration, resulting in muddy, booming sound that makes it difficult to discern where sound is coming from.

Featuring patented multiple-input/multiple-output (MIMO) mixed phase impulse response correction technology, Dirac Opteo Professional solution addresses these challenges by enabling all the speakers in a car to work intelligently together and co-correct each other’s impulse response.

The solution “erases” the car cabin – removing the unwanted effects of the cabin in ways previously regarded as possible only in theory. It also creates ideal loudspeaker responses for maximum fidelity and achieves unparalleled bass performance. Sound is richer, more balanced, more dynamic, in every seat. Occupants hear deep, clean, and tight bass free of resonances rarely heard in a car. With immersive content enabled, ET7 brings a concert-like sound experience – where transparent, genuine sound embraces occupants like they were listening live.

“Dirac is the world leader in automobile audio optimization, thanks to our solution’s unique ability to maximize the sound created by today’s increasingly complex, immersive car audio systems,” commented Lars Carlsson, Dirac General Manager of Automotive Audio. “The more speakers that automakers use to achieve a signature sound, the more important it is for Dirac to digitally optimize their performance and ensure the perfect listening experience, especially when enjoying immersive content.”

Continued Carlsson, “The NIO ET7 includes a sound system worthy of a concert hall. Dirac is proud to enable the faithful reproduction of drivers’ favorite, most immersive sound experiences. With NIO, we are raising the bar for in-car sound experiences.”

Dirac Opteo Professional solution is built upon Dirac’s industry-first Intelligent Audio Platform (IAP). It is a data-driven measurement system, semi-automatic tuning tools, integrated sound optimization algorithms, and an I/O to h/w platform. This enables manufacturers to achieve perfected sound faster, more easily, and consistently across vehicle models.

The NIO ET7 will also be the first car model that obtains the certification of “Dirac Pro”, a quality seal of top-class sound performance – according to Dirac standards
