Every revving engine and racing sound effect in Evolution Studios' upcoming game, DriveClub, has been created from recording noise from each individual car, audio manager Alan McDermott explained via the PlayStation Blog.
Although the team initially approached manufacturers to buy samples, they eventually began traveling around the world to capture audio. More than 16 mics were used for each car, with some totaling "26, even 27 in one of them," McDermott said.
"We've been chasing these cars around the world," he says. "There aren't that many Pagani Huayras available. They don't just send them out on a whim. It's in Japan on a Wednesday, it'll be in Italy on Saturday... we chased them. We've gone all out."
The extensive hunt was part of Evolution's desire to bring the engines to life and step away from the work of its competitors.
"It's what makes you feel connected to the road," McDermott said. "Coupled with the physics and the handling, I'd say the audio is one the most important aspects of the experience. If the audio sounds wrong it breaks the entire experience. The whole connected experience goes right through from physics to audio.
"Maybe not everyone will notice everything we've done, but we're obsessive about this stuff and we go the extra mile for the small percentage of people who will notice."
