Forza Horizon 5 utilises ray tracing for more immersive audio

By Sean Carey,
In a new livestream, Playground Games discussed Forza Horizon 5's sound design, revealing that ray tracing is being used to enhance the game's sound design and that over 320 brand-new car recordings have been added.

Forza Horizon 4 was criticised by the Forza community for its lacklustre car engine sounds, and it seems that Playground has been listening as it has put a much bigger emphasis on sound design with Forza Horizon 5. During the latest "Let's Go" live stream, lead audio designer Fraser Strachan and creative director Mike Brown spoke at length on how Playground recorded the various car sounds and some of the new techniques the audio team used to get accurate sounding engine noises.

Strachan revealed that Forza Horizon 5 utilises ray tracing to enhance the game's audio. The game sends out ray-traced audio paths which can detect various objects such as buildings and trees in the game world, meaning you'll hear the sound of your car's engine bouncing off buildings as you scream past. Environments will all sound different, too — driving through city streets or in a more urban setting will sound crisper and pronounced, while speeding through an area with thick foliage will be more muffled and organic.

The team has also been hard at work recording a bunch of new car sounds for Forza Horizon 5. Over 320 brand-new car recordings have been added on top of Playground's already existing library of car sounds.

In the video embedded above, Playground has detailed a new feature coming to Forza Horizon 5 called Audible Upgrades, which allows you to change the intake, exhaust, and a variety of other sounds on your car and hear in real-time what your engine sounds like as you're making an upgrade.

In a previous livestream, Playground shared new details on Forza Horizon 5's new weather system, which is both regional and seasonal.
