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

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 :)

I foresee someone making a rendition of the 'AAAAAAUUUUUUUUUUUUUUUUUUGHHHHHHHH' snoring meme. This was such a fun watch!

Watching this whole project evolve has been mesmerizing. I'm a 3D artist and I'm making 3d models of my own car designs to eventually take as mods in games like AC and BeamNG, this whole engine simulator project is great stuff to design sound for these custom cars. Glad to be a supporter

Can't wait for the final version to release and see the community compete to make the most cursed engine/sounds possible

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

So nice to “meet” the Mrs! You both are so great

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. :)

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.

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.

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!!

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

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!

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

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

never before has a single cylinder lawnmower engine sounded so angry

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!

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

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!

Actually laugh out loud at the 3am parking lot 😂 Awesome work mate.

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.

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

Ange is a really incredible programmer

man the intake opening sounds _amazing_

You're one of few channels I don't skip ads on

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!

This is incredible stuff man! Can't wait to eventually try this game and the chance we may see this simulation get implemented into BeamNG gets me immensely hyped

This is amazing. I'm so happy someone is finally working on something like this.

I cant wait for the final version i love engines and everything about them if i had the chance to build an engine from scratch i would but im broke so i cant, but this game is the best for now

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)

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

This is amazing! The direction this project is going is so exciting!

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!

This sim is absolutely amazing. I love seeing your videos pop up into my recommended cuz I always know it will be a great watch. Keep the great work up!

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

i enjoy very much the sound comparisons you make in the video. super cool can't wait to see how it evolves !

i love these devlogs, it's a mix of learning and comfort. thank you, ange.

Incredible work, it is great to see every video sunds better and better.

glad to see the progress on this, it's reassuring to know that there is always an improvement every time.

Phenomenal work! There is tremendous value in being able to see and hear the simulation in real time! 😎❤

I'm not even that interested in engines or programming but I can't get enough of these videos. What a journey so far!

just finished this video, absolutely incredible

That's already crazy! I love your work and cant wait for the next video already

This is absolutely amazing stuff. I've been following you for a while now but this is next level impressive even when compared to your previous stuff. Can't wait for games to incorporate your work so we actually have accurate sounds FINALLY.

Been waiting for this for sooooooo long. im a big fan of engine sim and have been here since day 1. love your work and i am excited for the es3d. ill buy it asap

Seriously incredible. You are right up there with the best dev/dev log youtubers. I have a hint how hard what you're doing is and your results floor me every time

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

Excellent work as always! The sound changes are really something, and I think they're helping me understand how cars sound the way they do in real life. I also appreciate how you mention the math without talking about how it's "scary" or whatever and just dive in to how you solved it.

There's so much that is possible with these variable simulations, i'm absolutely amazed! This, this will get all the attention it needs. I'm sure people will make even more insane content than ES2D

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

I'm so happy to see the way this project is going, and to be honest am looking forward to this more than any AAA game coming out haha. Love your work Ange!

Lovely work. Excited to see how this continues to progress.

Very excited with the progress made on es3d!

I cant help but realise how similar and soothing to listen to you are, it gives me straight up Greg's aircraft and automobiles vibes- Its so comforting, and that's the best way to learn a thing or two, three - make that ten :)

Incredible! That is turning into a great future tool for engine optimization.

This is so awesome! when its out i am going invite my dad and play around with it. Its going to be fun!

this is insane, it has a lot of potential. keep it up!!

The audio from this simulator is getting shockingly realistic. Y'all are killing it I'm so impressed. Its getting to the point where someone could design the perfect sounding exhaust on here and then make it in real life for their car!

Dude u are a crazy guy! As an engineer i love to look your videos and follower your work progress ❤

Amazing work, I am blown away yet again

This is gonna be a game changer for sure, can't wait to see the finished product

Wow it sounds very realistic, I have heard many motorbike engines at around 50-100cc and I will say they sound very similar to the ones that are the same displacement in this video

This has a lot of potential for modding games like BeamNG or other racing games

This looks and sounds like it'll be an amazing program and an absolute dream playground for ICE enthusiasts.

That thing sounds incredible even before all the steps you mentioned.

This is really cool, I love your new engine model it sounds amazing, as a demo you should release that to people to see what they can do with it

Your attention to detail and dedication is impressive! I imagine this simulation is being designed for games but wondering if it would not be useful for engineering work in general,Keep going!

This is so cool! Go go go Ange!

What you're doing is just amazing

There’s so much educational potential here. I hope he makes the simulation easy ish to understand for people who don’t know much about engines already (me) because it could be a great learning tool.

Splendid work Mr and Mrs TheGreat!

this man's going places, impressive work ngl can't wait for ES4D 🔥🔥🔥

You are amazing this work is so valuable. Awesome stuff!

Absolutely incredible once again

This is absolutely brilliant!

Incredible. Every video blows my mind.

It actually sounds like a 1 cylinder four stroke, well done

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.

This’s are damn impressive. Genuinely sounds like an engine

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.

Incredible work!

Mind blowing, once again!

This is great. The engines really sounds like they have inertia now.

This is incredible work

I like how you introduced the reverb. You are more intelligent than I.

This is awesome! I can't wait for the ability to make my own engine with real 4 cyl inline engine :d

The original Engine Simulator was already amazing, and now you're blessing us with this masterpiece. I can't wait to see how it evolves. This is really going to send a shockwave through many communities (pun intended).

5:16 OH MY GOD! That does not sound like a simulation AT ALL! Great job dude, hopefolly in the future i will be able to donate some money every month for this project.

This is outstanding work, my guy... please add a cylinder wall that absorbs back pressure resonance differently based on aluminum density vs cast steel density

Godlike as always. This is what they mean by a 100x developer.

I'd love to see a technical breakdown of those simulation improvements you made!

It's looking good! It would be great if it can simulate turbochargers/superchargers in the future as well.

If this gets integrated to beamng at some point it will be huge!! Pioneering stuff, great work again! 🎉🎉

Love how far this has come, dude. I got a suggestion for an engine to put into the Simulator. Supposedly, Mazda is working on a 2 stroke engine that works like a 4 stroke. Can you try to recreate that engine in the Simulation so we could see what different cylinder configurations sound like with Mazda's setup?

It would be interesting to see VR implementation in the simulator. As you mentioned that the new Engine Simulator will allow you to change the microphone position in 3D space, it would be pretty cool to be able to walk around a 3D rendered engine and listen to certain parts closer by getting near them.

i'm impressed how you made a 1 cylinder sound that deep.

You know its a good day when this genius has posted again

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

God damn this is getting really impressive

Sounds amazing
