Same engine, completely different sound
When I say symmetric, I mean the same on both sides in form and function. However, what is important according to my model is the total time it takes for the sound pulse to get from exhaust port to tailpipe. I experimented with moving a simulated muffler forward and back on one side of an...- UdjatEye

Same engine, completely different sound
My simulation is of a cross plane V8, and I haven't done a flat crank V8 yet. In a cross plane V8 no two cylinders fire at the same time, the power strokes are all spaced 90 degrees of crank rotation apart. However, each bank has an uneven firing order so that it isnt r-l-r-l-r-l-r-l but...- UdjatEye

Same engine, completely different sound
Last weekend I programmed a software sampler to simulate any engine configuration based on the firing order and exhaust manifold pipe lengths. The details are boring, but basically for a V8 sound I have 8 single cylinder pulses playing at the same time, but phased 1/8 apart, and each with a...- UdjatEye
