SOUND ON!
First draft of synthesized engine sound. this is also running in a handmade audio engine written with WASAPI.
Took a while to figure out, and I have no idea what I am doing nor have I ever dabbed in synthesizing sound before.
This uses a combination of sine, sawtooth, noise, and square functions that generate harmonics an are modulated based on different engine aspects.
Will likely modify this down the road but this is a first passable draft, now we have engine sounds!
here demonstarting changing different engine aspects and hearing the corresponding changes in sound. (added a basic FFT function to visualize the EQ curve in the bottom)
