In the high-octane realm of racing games, where the roar of engines and the screech of tires are as crucial as the visual blitz of speed and scenery, Gran Turismo 7 has revved up the game world with its impressive dedication to audio authenticity. The painstaking efforts of Polyphony Digital’s sound engineers and designers to capture the raw, exhilarating essence of real car sounds were highlighted in a deep-dive session during the CEDEC and Kushu Game Developer Conference in Japan. This rare peek behind the curtains not only showcased the lengths to which the team goes to ensure acoustic fidelity but also hinted at exciting potential additions to the game’s already vast car roster.
The journey of sound in Gran Turismo has evolved significantly over its 25-year history, transitioning from simple digital audio tape recordings to sophisticated multi-channel setups that capture everything from the growl of the engine to the subtler notes of interior acoustics and air intake. The quest for the perfect sound has led to experiments with over 50 types of microphones, settling on the Sennheiser MKH 60 for its sharp directivity and resilience at capturing high-pressure sound levels. This quest for acoustic perfection is indicative of the series’ commitment to realism, aiming to immerse players visually and sonically in the racing experience.
The process of recording these sounds is a meticulous one, involving sessions at facilities across Japan, Europe, and North America. Cars are placed on hub-type Dyno packs, which simulate real driving loads, while a variety of microphones strategically capture every nuance of sound from different parts of the vehicle. This dedication extends to tire sounds, with the sound team collaborating closely with tire manufacturers to record the unique sounds of tires on various surfaces including asphalt, gravel, and even snow. It’s this level of detail that enables Gran Turismo 7 to offer an unparalleled auditory experience, whether you’re tearing down the highway or kicking up dust on a dirt path.
Gran Turismo 7 doesn’t just stop at replicating existing car sounds. The Advanced Engine Sound Synthesizer allows the sound team to create engine noises for futuristic or concept vehicles that haven’t even hit the road yet. The introduction of 3D audio further elevates the game’s aural landscape, offering players a more immersive and spatially aware auditory experience, adding depth and realism to the virtual racing environment.
The dedication of Polyphony Digital to capturing the essence of each car’s sound is a testament to the Gran Turismo’s commitment to realism and authenticity. It’s this unwavering dedication to the smallest details that sets the game series apart as one of the gold standards of racing games. For players, this means not just seeing their dream cars in stunning detail but hearing them roar to life with unprecedented fidelity. As Gran Turismo continues to evolve, it remains a beacon of how technology and passion can combine to create an experience that respects and elevates the reality of racing, ensuring that every rev of the engine and screech of the tires is not just heard, but felt, by racers worldwide.
