As of recently, I've been getting recommended videos by William Moser on YT, a guy who creates "audiovisual demonstrations of cylinder firing orders". The way he did it was seriously impressive, and in most engines he showed, it sounded pretty realistic, too. Here's an example of the firing order of certain Ford V8s. Here's another of a Subaru's boxer engine. It even has that trademark Subaru rumble. So it got me thinking, I know the sounds in this game are synthesized, but what I always figured was that it was just a simple pitch shift, like sounds at multiple RPMs just strung together. But what if you guys did it similar to this? What if you simulated sounds of the individual cylinders, increasing in speed/pitch? Would this be viable? Would it be pointless? I don't know, I just figured it'd be an interesting experiment to mess with.
