I would only make a small suggestion for dealing with a large project like that. The audio is an immersion killer for me too. I want this to not only be enjoyable for myself, but for everyone else who cringes at the current in-game sounds haha :-D I will be open to any and all input/suggestions, requests, modifications. For example a Boxer engine will sound just like an actual Boxer engine because of how it's built, same for different sized and shaped I4's, v4's?, v6's, v8's, v10's, v12's, and so on. Modeling every aspect of the engines from rough running, bad tunes, good tunes, broken parts, performance vs stock parts, cam timing differences, cylinder fire sequence differences, high compression vs low compression, turbos, superchargers, intake/exhaust length & shape, etc. Originally posted by Dromeda:I am actively working on a realistic engine sound mod as we speak.
