Engine Simulator: produce realistic sounds from various engine parameters

For ages I've wanted to simulate different designs for exhaust headers and systems, to be able to possibly create different/interesting sounds from certain engines - i.e. can you add some additional headers with a different length and make an I4 sound like an I6?

FYI, this software is Windows-only for now, but there appears to be an active effort to make it cross-platform: https://github.com/ange-yaghi/engine-sim/issues/2#issuecomme...

Absolutely amazing. I wonder, do games like GTA simulate those sounds as well, or is it pre-baked somehow?

GTA used a combination of pre-recorded real life audio and their own granular synthesis engine. (Granular synthesis uses sampling, but cuts up the samples into tiny pieces and processes them in various ways.)

This is great, I'm watching the video on YouTube now... Are exhausts/mufflers modelled?

If I recall correctly he modeled the acoustics of the exhaust using equalizers and filters, so not really simulated

Wish I was doing something interesting like this for a work, instead of working on boring SAAS stuff

Could use convolution with recorded impulse response (IR) files to achieve realistic results for different exhausts.

This is so cool and it's amazing to me that a single programmer was able to do this as a hobby project. (To me it's magic, I know to some this a just a big project).
