    I wonder if this could be converted into a web application, maybe using WASM? I'm sure a lot of people here want to try it out on their own, but for me the build process is daunting as I haven't written C++ since college days. A web application would be very accessible.

    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...

    The sounds generated by this are very impressive - it is an actual simulation of the entire combustion process.

    Best parts are the engine sound under load, slight delay when opening throttle and changing down a gear to force engine braking.

    This is great, I'm watching the video on YouTube now...

    Are exhausts/mufflers modelled?

    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?

    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).

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

    It would be epic to make something for this guy.

    This is so cool. It makes me wonder what kind of amazing simulation software is behind closed doors in car companies.

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