Techno Revolutionizes Car Sounds

author: FutureCar Staff    

Electric vehicles are giving automobile companies a chance to reinvent how cars sound – and many are turning to producers to help them create radically new sound palettes.

"I'm driving in a black on black in black Porsche 924." With these words in his classic 1985 track, "Night Drive (Thru-Babylon)," Juan Atkins made explicit the nascent connection between techno and cars.

It was not unprecedented. The first major piece of electronic pop music, Kraftwerk's "Autobahn," was about driving down the highway, and Gary Numan evoked cars as safe spaces in his landmark "Cars."

But Atkins, recording as Model 500, connected the dots between the Detroit automobile assembly lines, the man/machine fusion of the automobile, and techno production, itself a kind of cyborg relationship between musician and electronic instrument.

With the rise in popularity of electric vehicles (EV), car manufacturers are taking the opportunity to redefine the sound of the automobile. Aside from tires rolling on pavement, EV are almost completely quiet. There's no engine noise because there's no combustion engine. Because of various safety concerns, EV are required to make some kind of sound to alert pedestrians to their presence. Just what form that sound will take, however, is up to the companies themselves.

While some manufacturers have stuck with the old script, synthesizing the sound of old-school engines, others are getting more creative. There are cars with samples of the human voice as part of the ‘engine' noise. Another incorporates a didgeridoo. These are not machine sounds but essentially human sounds. And the people championing this redefinition of how a car should sound are often electronic musicians.

Richard Devine straddles two worlds. He's known as a musician but he's also a sound designer. This includes cars. He's lent his talents to Jaguar, on the C-X75 prototype and I-PACE, working on both engine and interior sounds.

While Kyma and SPEAR are high-end, professional applications (sound designers have long used Kyma in major Hollywood films, for example), Richard also employed software that we as electronic music producers will know: Max/MSP and Native Instruments Reaktor.

Cars are extremely sophisticated machines. That includes their audio environments.

"The software that is running in the I-PACE car is completely proprietary," says Richard. "I designed and prototyped the synthesis engine in Reaktor and the rest was redesigned by two other coders. The system had to run on this proprietary playback system in the car that was much more limited compared to my computer, so there were lots of changes and limitations we had to deal with."

As cars are dynamic, the sound engine has to be as well.

Techno producers have been incorporating the sound of Roland synthesizers into their tracks since the beginning of the genre. Now cars are getting the same treatment. Japanese manufacturer Green Lord Motors (GLM) tasked Roland with creating the audio environment for its 2014 Tommykaira ZZ car. In turn, Roland adapted its SuperNATURAL sound synthesis architecture, as featured in the Integra-7 and JD-Xi, for the EV.

When asked about the biggest challenge involved with the project, Satoshi Wakuda, the head Roland engineer involved, explained that it was matching the change in the sound of acceleration and speed. This required a complete overhaul of the existing synthesis code to work in the car.

Recently, there's been a distinct move away from recreating the sound of engines of the past and instead creating a new palette of sounds. This comes as a direct influence from companies employing musicians to act as sound designers.

Synth god Jean-Michel Jarre has recently worked with Renault to create the sounds for its new cars. In a series of promotional videos, Renault's representatives use words like "caring" and "friendly" to describe the sounds that they have developed with Jarre. This is a far cry from the kinds we usually hear, which tend to be aggressive and loud.

Car companies are also aware of how the sounds of their vehicles contribute to urban and public spaces. We have designed cities around cars, after all. With EV cars increasing in number, we now have a unique opportunity to re-soundtrack our urban spaces and create environments that are embracing of humanity.

Along with creating new public sounds, modern EVs allow us to customize their interior sounds, as we would a personal Spotify playlist.

As electric vehicles come of age, automobile manufacturers are taking the opportunity to redefine what the sound of a car can be. Across the board, they're pushing things into a friendlier and more human-embracing zone.

This is all very techno in the original sense of the term. Rather than subsuming their own humanity to prioritize machines, people are now working together with machines to create a better world, whether that be programming beats on a drum machine or using modern synthesizer technology like SuperNATURAL and Reaktor to give musical life to automobiles.
