For example in forza, the game plays engine sounds based on how much we press the button. Are there different sequences of clips ? If yes how do they blend so well ? Or are they synthesized dynamically ?
There are so many parts to it as well - when the gear shifts, when you suddenly slow down at high speed, when you suddenly accelerate from stop. They all seem very realistic.
Edit: Thanks for the great answers everyone 🙏
There is also a one man wonder effort to improve the sound work of simulated engines by “simply” simulating the flow of air https://www.youtube.com/watch?v=J11c8mMN1PA
