A question about cars' sound simulation.

Hi guys! Recently I'm conducting an experiment about automotive cars and I made up a scene. I use BeamNG.Drive as the sound resources. Now I'm wondering how BeamNG gets such vivid sounds from all kinds of vehicles. I have some basic guesses. One, they were recorded in reality and processed by some designers. Two, they are all made up, like making the sound of a car by cans. Three, they are simulated by some professional software, like Fmod...Now I'm really confused, and it's very important for my experiment. So I wonder whether there is an official documentation which introduces the sound of the cars in detail.
So guys, if you know anything about this question, I'm more than happy to discuss it with you.

 

BeamNG uses FMOD for its sound simulations, I think

 

Thank you for your reply But don't they need some original car sounds as resources to simulate a real car move? And I have a little question: if they really use FMOD to make the sound, it means the sound is not that powerful, right? It just makes the players feel like it's a real car but in reality, maybe it's totally the other way around.

 

this video goes through the process they use for implementing sounds:

 

Hi! Thank you for your reply! And now I know how they make the scene sound and it's so real. But actually, I'm more curious about how they process the car's moving sounds, like firing up the engine, car accelerating, or decelerating, etc. But I can't find the related videos from the official BeamNG channel on YouTube: (

 

I'd pop in there and ask TDK https://www.beamng.com/threads/audio-feedback-thread.44084/

 

Good suggestion! Thank you for your help, I'll do that!
