How are engine sounds in racing games played ?
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 🙏

Most older games will have 2-3 engine loops that they will blend between and pitch accordingly, however Forza 5 specifically was the first in the series to use granular synthesis which is a much more modern approach.
These will have a series of sound files including all the different parts of the engine, exhaust, turbo, etc. Then the software slices these files into tons of pieces in real-time and plays the slices based on the players inputs.
It’s tricky to explain without examples, so here’s a video that does a decent job of explaining how it works in music: https://youtu.be/ftDLRYnRYZQ?si=SEHOl55K7rimi4Eu
Some electric BMWs do the same on the literal automobile, too. It's an EV that sounds like a high performance ICE both inside and outside the car.
Can you buy different sound packs? I would want mine to make a "wub wub wub" sound...
I want mine to just scream "AAAAAAA-" continuously and base the volume on the speed
And if someone honks it should scream in fear too.
