F1 Audio Revolution: How Mics on Air Ducts and Exhausts Enhance the Roar of Racing!

Director Joseph Kosinski emphasized a key directive for the audio specialists on his new movie “F1”: He aimed for maximum immersion, desiring the viewers to experience the sensation of being inside the race car themselves.

However, capturing genuine Formula 1 sounds was unprecedented. Juan Peralta, a re-recording mixer, noted, “Formula 1 has always been heavily guarded with its rights, which has prevented any films directly focusing on it. The sensation of being inside an F1 car in a cinema setting is quite novel. We’re familiar with race movies featuring different cars, but Joseph really wanted us to capture the essence of being at the races, feeling the velocity at play. Our main challenge was ensuring that whenever the scene involved the car’s perspective, the audience could really feel it and sense the speed.”

The Apple Original Film features Brad Pitt as Sonny Hayes, a former Formula 1 racer coming out of retirement. Javier Bardem portrays Ruben, the leader of a struggling race team who persuades Sonny to rejoin the sport and mentor a young racer, Joshua Pearce, played by Damson Idris. The story unfolds mid-season, with Ruben hoping Sonny’s involvement will secure the team a podium finish.

To authentically record the car sounds, supervising sound editor Al Nelson explained that initial recordings were done using Formula 2 cars driven by Pitt and Idris. Although these recordings were valuable, they were placeholders for the actual F1 sounds needed later. “It was an excellent initial step to understand how to effectively mic these incredibly loud cars,” said Nelson.

The production team collaborated with Mercedes AMG and Formula 1 engineers to construct actual race cars capable of carrying filming equipment. Nelson added, “Real F1 tracks and real cars were used, with Gareth using specialized DPA microphones akin to those used in actual races, allowing us to capture sounds from the cars and track with precision.”

John explained how the microphone packs were secured with cable ties in risky but acoustically strategic positions near the exhausts to capture intense, authentic soundscapes. “We explored various placements like air ducts to best capture the robust sounds needed for an immersive experience,” he said.

Beyond the sounds of the cars and turns, capturing the ambiance, environment, and crowd reactions was equally vital.

The movie’s journey follows the F1 global circuit from Silverstone to Las Vegas, culminating in Abu Dhabi, with each track imbued with its unique character and atmosphere.

In Las Vegas, Gwen Whittle noted the diverse, predominantly non-English-speaking crowd. “The grandstand echoed with Spanish, Italian, and French, reflecting the international fan base likely due to the sport’s burgeoning popularity in the U.S.,” she observed.

Contrastingly, Whittle found the pit lane surprisingly silent despite the frenetic activity. “The pit crews worked swiftly and silently, much like ninjas, focusing intensely without a word,” she said.

The team spent considerable time at Silverstone, the site of the British Grand Prix, where they recorded extensive track sounds. “We stationed ourselves and our microphones all around the track, capturing the dynamic race atmosphere during two grand prix events,” John recounted.

Filming was tightly scheduled around actual races, with around 30 cameras capturing the high-speed drama as Pitt and Idris took to the tracks.

During filming, real-life racing incidents were captured, adding authenticity. “We witnessed and recorded actual crashes and racing events, integrating these real moments seamlessly into our narrative,” John explained.

Integrating Hans Zimmer’s thrilling score was another layer of complexity. Gary Rizzo discussed the challenge of balancing the dynamic score with the sounds of the race to maintain emotional and adrenaline-driven intensity.

Real F1 commentators, Martin Brundle and David Croft, were brought in to add authenticity, requiring several ADR sessions to perfect their commentary. “Balancing the informational needs of F1 novices and aficionados through their commentary was a delicate task,” noted Whittle.

Among the sequences, Silverstone was particularly challenging due to its lack of musical accompaniment, relying solely on sound effects to maintain intensity, according to Peralta.
