In this video I simulate a variety of engines including:
1. Subaru EJ25 with equal length headers
2. Subaru EJ25 with unequal length headers
3. Toyota 2JZ
4. 60 degree V6
5. 90 degree odd-fire V6
6. 90 degree even-fire V6
7. GM LS
8. Ferrari F136
9. 9 cylinder radial
10. 1LR-GUE (Lexus LFA)
11. Rolls Royce Merlin V12
12. Ferrari 412 T2

Hey guys, hope you liked the video. I decided to talk in this one, let me know if you prefer this over the last video. Thanks for watching!

Something to consider (you probably already have) is licensing this tech to game makers NOT as a real time simulation, but to provide a workbench where they can develop and customize their source sound samples. You could envision an API and generative workflow where custom samples could be generated based on player input, then silently rendered and captured for use in the cheat sound engines they already use.
-
Nice to see that even BeamNG supports you and therefore recognizes the potential of your simulator for other simulations. Great work on the unequal length headers!
-
Aw hell nah Bocchi's anxiety turned her into an engine now
-
That Ferrari V12 sound is just pristine.
-
the sound of engine braking in ES never ever stops being jaw-dropping
-
The EJ25 with unequal headers was so accurate it startled me
-
Your 5.3 LS at idle literally sounded identical to my Silverado when I started it with no muffler. That's impressive!
-
I like how the cylinders resemble bocchi's hair. You're the engine hero.
-
There must be nothing more satisfying than writing a physics engine and getting that validation that you've simulated everything right when the sounds are so close to real life. Impressive and promising.
-
I would love to see a rotary engine in the simulator soon!
-
The non-blown version on Merlin is called Meteor and was developed for tanks.
-
Just gotta say again Ange, these are by far the most realistic simulated sounds I've ever encountered. That V10 sounds insane. This project is so cool. Can't wait for the eventual 787B simulation. (good luck!)
-
From a musical perspective it's fascinating to hear how the more balanced the engine and headers are the purer the 5th tone is (2nd harmonic @ 3/2 ratio) And past 6 cylinders a major 3rd tone appears.
-
The F1 engine at the end is an amazing demonstration of data compression! The artefacting you hear is because the physics calculations have a defined resolution/bit depth so when the speed gets past that limit, the signal becomes lossy. I've understood the concept for a long time, but seeing it come up sort of organically in the simulator made it click in a different way for me. Pretty cool
-
I could recognise the ferrari feeling on the V6 and the downshift on the LFA with closed eyes, extremely impressive work
-
im very impressed with the LFA. i think it only sounds off because of the special exhaust the LFA features. in case youre reading this and don't know, the LFA design team actually hired Yamaha to help nail the sound both in and out of the cabin, which would be difficult to simulate. amazing work as always ange!
-
You could improve your demo runs by adding flyby's, incorporating the doppler effect. It would help showcase airplane engines for sure. Stellar work so far!
-
The unequal length headers on the Subie sounds a lot better! Looking forward to the forced induction sounds. Been super cool hearing all the different engine types.
