Real-time Engine Tuning - Engine Simulator Devlog 4

[@waltermorgenroth7872]

The microphone placement concept is far more important than I realized. If you think about it, the audio samples being played are from the perspective that you're right where the exhaust is exiting from, rather than hearing the waves as they expand outward in other directions in space. This must be what's making the exhaust notes sound so tubular and resonant in this stage

[@cor74]

I think you might be right, its like when a mic is way too close to a persons mouth and you hear too many articulation sounds.

[@xenn4985]

That can be done in post. However the reverse cannot be done. So its best to start with the mic right up in there.

[@tacticalidiot175]

It could be done like BeamNG does, with separate audio emitters placed in different areas along the car and the engine components.

[@Bassalicious]

Also directional focus is linked to frequency in pretty much any physical sound source. Higher frequencies will be more directional and lower ones more omni-directional due to diffraction. I think it would be great if Ange could implement a filter with the cut-off frequency linked to how much the normal vector of a sound source is pointing away from the mic or something like that.

​@@xenn4985acchshullyyy if you have an impulse response you caaaann convolve it with the inverse impulse response which would teeeechnically give you back the original sound 🤓🤓🤓

That’s amazing that even at this early stage I can hear and differentiate few engines: - 2 stroke chainsaw - something like excavator/tractor engine - a cow ready to be milked Also I’ve heard a few backfires, that’s really cool :)

Engine Simulator really has come a very long way from where it started, you should be proud of yourself Ange, you've made an amazing software. :)

[@lntegrate]

16:26 you've officially made an french engine. it goes "oui oui" every time you rev it

[@zacbrown8191]

Dude this is amazing stuff. I've worked as a mechanic in some for for 10+ years and even the basic simulations you've shown here mimic alot of what real world experience has shown me. And as props to your skills @AngeTheGreat, I've used ES2D to replicate real world engine builds (mostly vintage motorcycles) and corresponding dyno figures to a remarkable level of accuracy. You're doing amazing work!! I'm currently using ES2D to build and tune a Bonneville land speed bike, and by all accounts from many different experts everything the simulation is telling me (accounting for altitude change) is within expected ranges. I can't wait to see ES3D and try it out!!

[@NFBartos]

Dude that's incredible!

[@RagingHadron]

I don't want to detract from how impressive this all is, but I do want you to know that my favorite part of the video was 9:40. I was not prepared for the slide-whistle sound to turn into goat noises.

[@TheOriginalGeekyNoob]

That's uncanny to see modelled, absolutely amazing - cannot wait to see where this technology goes!

[@kvaek]

Babe, wake up! Ange posted! Excited to see the progress :-)

[@mrkosmos9421]

Someone else might have asked for this, but the ability to turn on motion blur for the piston would really help visualize its speed, especially when it starts to look like it barely moves between frames. Also I'm really interested in the new simulator improvements!

[@spongeborgtheford4971]

I cannot wait to hear this simulator with multi cylinder engines! Especially with the new intake noise. It's gonna be so goooooood!!!!

[@booperduper8816]

Bro this literally sounds like a straight piped minibike motor. It's crazy accurate

[@kahlzun]

the pressure wave from a tuned expansion pipe also allows you to create a "valveless pulse jet": a jet engine with literally no moving parts.

[@dingo-gorditas]

man the intake opening sounds _amazing_

[@aaaa9r]

Amazing work!! I want to point a suggestion: I feel like a proper motion blur effect would do wonders for your engine. For instance, when a piston starts to get really fast, it looks kind of choppy because every frame generated is visually perfect. In reality, our eyes don't see fast things that way. When a fan is spinning fast, we see the blades in a very blurry way. And we know it's spinning really fast because we see it that way. I think it's called per-object motion blur, and some games do implement it correctly. It calculates the amount of blurriness of an object based on the number of frames currently displayed on the screen (because 120hz won't have the same amount of blurriness per frame compared to 60hz, assuming the framerate reach those values) and the speed of the object moving in the view/camera. Not the same as the usual whole frame/camera motion-blur, which can be a hit or miss, but most of the time misses the point of achieving a realistic representation of a speedy object in our eyes. I think I cannot give you a link without being shadowbanned in youtube, but there is a thread in the forum of Linus Tech Tips called "What's with Linus hate for Motion Blur?", page 4. There's a developer that worked on that motion blur for Crysis in 2010, and he goes with some comparisons and the reasoning behind. I find it super interesting, and suspect you might as well!

It's on my todo list, just haven't gotten to it yet. Thanks for the suggestion!

never before has a single cylinder lawnmower engine sounded so angry

[@dacxl36]

This sounds so much better/clearer than the original sim. Very excited for intake sound and custom exhaust pipes

[@identiticrisis]

Adding the intake sound source is probably the biggest improvement in expressivity for this model yet! The other stuff can mostly be faked with filters, including reverb and transfer, combined as one filter in fact. But without that single change that responds directly to the throttle input, it wouldn't feel half as involving. Really excellent work so far!

[@mprism7985]

excited to see how this could be implemented in gaming in the future, maybe 10-15 years down the line this will be the norm for racing games!

[@tomclanys]

13:38 the cute "pop" when changing the size :D

[@Timsturbs]

reverb and distortion are two really powerful effects that allow you to make your sound much more interesting and harmonically rich without much effort, actually one of the suggestions for beginner music artists is to limit usage those effects as much as possible as it can quickly get out of hand turning your work into a noisy mess. 4-6% reverb is ok for a little makeup, 6-12% to add a bit of space, more than that only recommended if youre going for ambient style of sound.

[@stuntvist]

You should try making something like a EU spec alu block M52 when you get to the point of having full blown engines running. They have a really whistly idle with stock cams at 600RPM so it's a good litmus test to see if even the weird niche edge cases come through in the simulation. Beyond impressive work so far though. Just absolutely amazing stuff from a pure nerding out over engines perspective!

[@Jamesfreezy]

I’m really looking forward to the release. It’s amazing how good this is already. Well done

[@TheDeathskull37]

I am so glad you posted this, because I have been thinking about tuning applications for your software. It would be amazing if you could input cam specs like lift, duration, and lobe separation angle, as well as injector specs (flowrate, number of injectors, port/direct/throttle body injection), and have an output for simulated AFR. These features as well as Volumetric efficiency/flowrate and timing tables would allow people to make tunes on virtual engines without having a physical engine in front of them, and make baseline tunes that can be tweaked and used later on a physical engine with the same specs.

[@GavinEarnshaw]

[@potato-km6iw]

we will definetely see this form of simulation in beamng, they are already supporting him on patreon, cant wait for it

[@trysta73]

I've been loving watching your progress on all this and I just keep thinking (especially after your trumpet simulation) about the real time audio synthesis applications of everything you've done and you have the makings of maybe THE wind/brass instrument plugin, maybe even some other interesting air vessel instruments like an udu. I don't want to encourage feature creep per say and I'm interested either way, but there is so many exciting potentials to the work you've done. (also thank you for talking about asset creation potential with this in general)

[@Aquatarkus96]

I would love to see this applied to musical applications as well, but it's only a piece of the idea. A big part of the issue is how do you translate the nuances of a performance into changes in the simulation? How do the actual controllers respond to different playing techniques? Do the physical sensors have the sensitivity and accuracy to make the sound that the performer is intending? A simulation like this one combined with the ability to control it through midi 2.0 might end up being a game changer in synthesizer tech, especially if an equally good wind controller is ever produced that works using midi 2.0

[@WarttHog]

I still chuckle everytime I think of trumpet simulator. So incredibly, technically good at being so incredibly musically bad, haha! The animated "lips" we're killing me, haha!

[@Landeville]

Now that's what I call simulated engine sound! I hope this technology ends up in BeamNG Drive at some point!

YES YES YES YES!!!! I was looking at old videos not too long ago and here we have a new one.

[@TheDaniel366Cobra]

YES! 2 stroke pipes! I have been waiting for it. All hail Ange the Great. What's interesting is that I thought 4-strokes did not benefit from an expansion chamber since they have valves direct fuel-air mix and exhaust gases. AFAIK in 2 strokes the purpose of the return wave is to push escaping fuel-air mixture back into the cylinder right before the piston closes the exhaust window, and 4 strokes don't have this problem.

[@Ironfist2211]

Got a good chuckle from the demonic entities. Can't wait to see this thing finished!

It would be interesting to see VR implementation in the simulator.

You have modeled the effects of air pressure changes and such. But I feel like it is missing the mechanical clicks and clacks. For example, I would expect the valves to make sound when they close. And possibly the cams lifting levers, or the whirring of the gears and bearings.
