Game developer Playground Games recently shared how ray tracing was used for the audio design of the upcoming video game Forza Horizon 5.
A new episode of the game on the official YouTube channel covered the various innovations that this game offered and one of them was the audio design. It was revealed that the developers are using ray tracing to enhance the player’s immersion in their driving experience.
Creative Director Mike Brown and Lead Audio Designer Fraser Strachan discussed how the principles of ray tracing were used to create the game’s audio design. What ray tracing does is that the game will constantly detect objects in the world. The feedback that comes from that detection is then used to deliver audio. Looks like a bat would use echo to navigate the world. In this case, the feedback from each object that bounces off is used to provide the appropriate audio for it, such as distance and sharpness.
Urban areas will have a noisier sound due to the many buildings in them, while areas with tons of trees and foliage will have a muffled sound instead. Ray tracing will intensify those with accurate audio.
Forza Horizon 5 launches on November 9, 2021 on Xbox One, Xbox Series X/S, and PC.
