Walk deep into Walt Disney Imagineering’s sprawling, surprisingly unassuming Glendale campus, and you’ll eventually find Studio C.
It’s where Imagineering mixes the audio for its attractions, but when I recently stepped inside, I quickly realized it was much more than a recording studio. The room is lined with dozens upon dozens of speakers designed to recreate the sound field of Disney attractions, letting Imagineers hear a ride long before guests ever do.
During my visit, I watched a live mix session for Zootopia: Hot Pursuit, Shanghai Disneyland’s trackless dark ride, and the experience was almost uncanny. Sound moved seamlessly around the room, tracking the ride vehicle as though I were actually inside the attraction.
That same room became the proving ground for one of Imagineering’s most unusual engineering challenges yet: figuring out how to mix the audio for Soarin’ Across America.
The reimagined version of Disney’s iconic flight simulator debuted this summer at both EPCOT at Walt Disney World in Orlando, Florida, and Disney California Adventure in Anaheim, California, timed for America’s Semiquincentennial celebration. Disney’s Unscripted behind-the-scenes video confirmed that Imagineers used the Apple Vision Pro during production of Soarin’ Across America, but it left one obvious question unanswered: why? That’s what I wanted to find out.
So I spoke with Greg Lhotka, Sr. Manager, Audio Media Design at Walt Disney Imagineering, who walked me through the surprisingly complicated process behind mixing one of Disney’s most technically demanding attractions.
“For Soarin’ Across America, we utilized Studio C not only as a production facility, but as a proving ground for an entirely new field-mixing approach developed specifically for this film. On the sound design side, we partnered with Skywalker Sound, and together we used Studio C to prototype and validate a custom speaker configuration that closely mirrors the unique audio architecture of the Soarin’ theaters.”
If you’ve ridden Soarin’, you already know why that matters. Riders are lifted into the air in three stacked rows facing a massive curved projection screen, while sound moves not only around the theater but above and below you as well. As Lhotka explained, the attraction uses a four-tiered speaker system — upper, mid-level, lower, and a dedicated floor array — creating an audio environment that’s far more complex than a traditional movie theater.
Having now ridden Soarin’ Across America several times, it’s easy to appreciate the result. The updated film sweeps from New York Harbor and the Grand Canyon to California’s rolling hills and countless landscapes in between through soaring aerial cinematography, practical effects, and a soundtrack that glides almost effortlessly alongside you. The audio shifts just as fluidly as the visuals, making each transition feel natural as the ride carries you across some of America’s most recognizable landmarks and scenic vistas.
Studio C could simulate much of that during production, but not all of it.
“For Soarin’ films, mixing historically required the construction of scaffolding inside the theater to reach the appropriate listening height for final mix decisions,” Lhotka explained. “Even then, the process was far from ideal, as the ride canopy significantly influences the acoustics. For this project, one of the key requirements was that the theater remain fully operational and open to guests throughout production — eliminating the possibility of scaffolding altogether.”
How do you mix a show with over 1,000 audio tracks and an extremely complex panning matrix while seated in a ride vehicle?
That constraint forced Imagineering to rethink its entire workflow.
“The challenge was clear: how do you mix a show with over 1,000 audio tracks and an extremely complex panning matrix while seated in a ride vehicle? The solution came through an innovative use of new AR technologies. By leveraging advanced screen-sharing capabilities, we were able to remotely control our production system — directly connected to the theater — while seated in the ride vehicle itself. This allowed us to place virtual screens in our field of view, effectively bringing the mixing console into the theater environment.”
Watch On
Before anyone tested it inside the attraction, Studio C became the test lab.
“Studio C once again played a critical role as our testbed. Over the course of a week, we evaluated multiple configurations to confirm that things could be controlled precisely in this way, and that the AR headset’s external cameras would allow us to view the film clearly in the theater’s low-light conditions while simultaneously monitoring the virtual screens. The final configuration exceeded expectations.”
Once validated, the workflow moved from experiment to production.
“This workflow was ultimately used as the solution — and it became the method by which Soarin’ Across America was mixed. The result is a soundtrack that was shaped directly from the guest’s perspective, using tools and techniques that reflect our continued commitment to innovation, immersion, and storytelling.”
Having experienced Studio C for myself, that revelation immediately clicked. The room is already designed to recreate the feeling of sitting inside a Disney attraction with remarkable accuracy. But even a purpose-built facility couldn’t perfectly replicate Soarin’s unique acoustics. The only place left to finish the mix was inside the attraction itself.
It’s an elegant solution that solved two problems at once. Guests never lost access to Soarin’ during production, and Imagineering’s audio team was able to shape the soundtrack from the exact seat every future rider would occupy. Rather than approximating the experience from scaffolding or even Studio C, the final mix was crafted where it mattered most: inside the attraction itself.
