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 🙏
I remember exploring the Road Rash files as a kid and each bike sound was a single short click that just repeated rapidly. Times have changed.
All sounds are short clicks that just repeat rapidly, if you think about it.
