the sound at 15:46 is absolutely insane

Engine go vroom vroom am I right 😁

that wobble sounds perfectly reasonable and realistic, it's probably a bad exhaust design and not a simulation issue

17:41 POV: You lost GPS acces and went too far off into the texan countryside when you hear a tuned tracker from behind start to overtake you lmao

Hell yeah, man's been cooking.

Holyyyyy the pull at 15:46 gave me chills

oh dude, the audio is sounding so awesome now! Your progress feels hard earned, and is showing fantastic results

The audio at 15:50 literally gave me goosebumps. This is the future of racing video games, sim and arcade. You deserve millions for this masterpiece of coding. You've done it, minus a few tweaks you said yourself you want to do, and with another head or two on the project in the future, you are well on your way to making some SERIOUS cash renting this software to big corporations for both fluid simulation purposes and game dev. You are brilliant.

I was one of the people who was a little disappointed at the single cylinder sound. This completely obliterated any concerns I had back then. Honestly this already sounds absolutely amazing, especially the comparison with the unprocessed sound from ES2D shows how far this project has come. This completely restored my faith and I will worship at the altar of Tubular until this gets released!

15:45 Jesus christ this sound is insane! I think I just had a eargasm

Everyone is saying this, and i'll say it again, the sound at 15:46 is CRAZY. I cant wait for more updates, this is looking incredible.

The trick to having multiple things operating on a single state is to double-buffer it so that CPU is reading from previous frame's output, and GPU is rendering with it, while CPU (or whatever device is performing the simulation step) outputs the simulation increment to a back buffer. Then you swap the buffers' roles. I'm sure you're well aware of double buffering, but sometimes we forget things!

ES3D sounds so much better than 2D, I cannot wait until I can play with this

The smile I had on my face after hearing the acceleration through the gears and that growl at 15:48 Excited for the future where we can test and hear the differences in exhaust layout for different engines. Imagine being able to find a good sounding exhaust for the S55 by building the engine and exhaust in this simulator and figuring out what makes it work digitally first

If I'm not mistaken, the wobbling you spoke about at 15:46 is a result of exhaust air resonating in the system. I think that sound happens irl too with some exhaust systems. You'll of course want to check and verify but if it is because of a physical property and not an issue with the sim, it means you're doing very good with the exhaust side of the simulation

The old simulator sounds like an electric toy in comparison, whereas if you close your eyes, you're absolutely riding that bike with the new simulator. Very well done.

The fact that this is absolutely pure output of the simulation and that it sounds so real is astonishing

17:43 straight up sounds like a tractor to me

I had no idea anyone complained about the new version sounding less realistic, and I'm giggling now because OF COURSE it initially sounded less realistic, it was really early in development. It's STILL really early but SO GOOD.

I hope this method becomes the industry standard. Engine sound is honestly one of the most important things to me in a car, and this will get the realism so much closer than it's ever been. Not to mention all the possibilities of simulating really uncommon/non-existent engine types. Like, I'd love to hear a 14 cylinder radial without a prop on it, or that Chrysler six bank 36 cylinder.

19:20 actually sounds like my miata with the muffler delete

19:07 the groan tubemobile approaches

The gritty sound that the new sim makes when rapidly changing speed is what really sells it.

that "wobble" is actually very realistic as some engines do that at high rpms under engine load (accelerating) I was chocked when I heard that and actually sounds a lot like my real bike at those rpm, Amazing job 👍 edit: while looking at the video again, the wobble appears when the presure in the intake valve increases, due to the high rpms/load ratio, some vehicle's get rid of that with some exaust desing but definetly this is prof that your simulator works beautifully

16:11 the resonance is a real thing, its good that its simulated. the reason its so prevelant is because usually resonance is a lot tougher when there are multiple cylinders going into one exhaust (im pretty sure at least) either way, it sounds very very good!!!!

15:50 hearing that wind up and gear up is just magical to me - keep it going man

Jaw dropping results. Looking very much forward for turbos to join the party. Keep being great, Ange!

18:50 You taking shots at Honda owners haha.

the walmart parking lot is hilarious i didnt expect that

I legitimately predict this will in some way shape or form find its way into almost every video game with vehicles in the near future

"If you're still running a core two duo rig in 2024 I'm going to tell you to seek help." That had me laughing way more than it should have.

Something i've noticed with car's exhaust is what i call the drainpipe effect. When the exit of the exhaust has a long unmuffled pipe section beforehand, for example vehicle with 2 mufflers but with rear muffler replaced with pipe, there's a certain warbling resonance that can be heard. Engine Simulator 2 has it, that sound was there around 15:17. Superb work.

Yoo that's totally Tubular

my jaw just dropped at around 16:00 in. I'm not even into cars and I was just amazed

I can't wait to hear a big V8 with the New simulation

I've got a 750cc GSXR, and that resonance sound you mentioned about the exhaust in the new simulation really does happen at certain RPMs. Your work blows me away. Intellect can take a man far, but your work and determination on top of it is what leaves me marveling at this.

Ange, seriously dude. Every single time you come out with something that blows my mind even more. your creation gives me GENUINE goosebumps with how good it sounds. But not only the quality of the audio, the visuals and intricacies you put into your work are stunning and jaw dropping. PLEASE DONT STOP! No lie, every time you demonstrate a new type of motor layout and you get on the gas, banging through the gears, it makes me shiver. Its amazing what youve acomplished.

It's a night and day difference! Sounds amazing!

god damn if the final product ends up in BeamNG then Ange better get some of that income, this is godly

I still come back to this video every few days just to listen to that sound at 15:46. It's incredible to the point where it's not the nerd in me that is getting excited, but the petrol head

The non processed comparison of OG vs current iteration ES is absolutely wild. What a staggering amount of process. Not to mention, it's still a WIP. I can't wait to hear the final version

how could have people said that his was a worse upgrade, like bruh this new hayabusa engine that uses fluid dynamics to make sound is so much better sounding. in this demo stage of the new engine simulator seems very damn good already omo

@AngeTheGreat I do hope this reaches you. Allow me to contextualize the following: I am a 20+ year master mechanic, who has personally owned, worked on, and operated 13 different cars/trucks, and 13 different motorcycles, and worked on countless others. I am mildly autistic, and thoroughly fascinated with the operation, and the SOUND of each and every component of an engine. With these traits in mind, I trend towards objectivity, and less towards overlaying my preferences and emotions (remember: autism. How to emotion??). I tell you that to tell you this: I'd like to express my observation, that those who seem to criticize and question the thing they have no control over, seem to react as such (YOUR project vs THEIR experience - come on, people. LET HIM COOK.). That being out of the way, I hope it provided context for my next statements. I have been following your progress on your previous projects, and I am thrilled that the almighty algorithm has favored you - YOU. HAVE. EARNED. IT. The path, and every milestone along the way, has lead you here. And I am ecstatic that it has. I am thrilled to be able to observe the fruits of your labor grow! I have trust and faith in the way you are tackling this project. I have a DEEP appreciation for everything you've done to create as accurate a simulation as possible. I'm not a programmer, nor am I an engineer. But I'm thoroughly impressed at the now raw, procedural sound you've managed to replicate - I was really tickled at how the old sim had additional audio processing to achieve SOME level of real-world sound, and how the new sim doesn't need it at all to sound just about perfect to real world! I am particularly interested at the content after the 16:00 minute mark - the 'wobble'. My intuition on the subject, and the reason I've decided to write and share, is thus: I have experienced this resonance, especially on motorcycles, where the experience is very raw, direct, and visceral. I think your simulation is extremely accurate! Resonance is a very big deal in the world of engineering an engine - it is absolutely crucial to scavenging, efficiency and performance. I know you already know that. So on to my intuition. If it's simulated, rather than addressing your code, which I feel the results would suggest is very accurate, I'd point you towards the area and angles of the intake and exhaust ports (particularly the exhaust, but both matter) and see if it does not directly correlate with a change in the behavior of the resonance 'wobble.' If these parameters are simulated, and changes to the design of the ports results in a direct change in the behavior of the resonance, I think we can reasonably conclude that you're 100% on the right track! And if these parameters are not simulated, then I am talking directly out the wrong cheeks and I would be embarrassed to have written this college paper and consumed your time in vain. Either way - I love what you're doing. I'd hazard a guess that most people who view, but do not comment, feel similarly, and trust and understand the kitchen is properly staffed - and those who criticize are the exact same people in starbucks saying their drink needs more ginger, and when the employee takes the cup, turns around and turns on the grinder for 8 seconds, then hands the customer the exact same drink, unchanged, who then take a sip and say, "perfect"!

Sounds fantastic dude. The deepening with exhaust length sounds really nice. The resonance "wobble" is accurate: There's always an RPM range where an exhaust sounds raspy and terrible. Also, changing cam profiles changes the sound of an engine dramatically. Very cool! Love your work

19:00 the fact that i know cars that sound exactly like this is crazy

I don't know if you have any musical inclinations, but it'd be awesome to be able to design your own brass and wind instruments with such an accurate simulation.

You are a real software developer and I love how you keep improving your project. I'm sick of other YT devs making single programs for each video

This is awesome. I hope you're truly proud of what you've achieved with this. Thanks for sharing with us all, I can't wait for further development!

This video makes me realize how the old engine simulator sounded like you were in a cabin of a car or something. Sounds muffled. This new version sounds fucking sick, can't wait to see what comes with it!

It's beautiful to me what technological advancements have enabled for hard working and brilliant individuals like yourself to create.

I like how the highest tier patrons of every channel have the craziest names

The first custom muffler design you made makes the inline-4 sound like an American V-8 at some points. I love the acoustics!

You know it's gonna be a great night when AngeTheGreat uploads

One thing you mentioned were junctions. I think those might help out with the simulation because instead of having to simulate multiple long pipes, there would just be the one pipe leaving the engine. I do know that exhaust systems tend to split and merge multiple times depending on the vehicle so it seems like something that is quite important to the sound. But regardless, this is a project I am deeply interested in. I have spoken to many people about this irl including my college professors. One of them even wanted to see about having you come in to present ES2D and ES3D.

13:54 a fully generated, purely digital combustion engine noise is amazing.

The fact that this is already approaching a level where it could be mistaken for a real sound is absolutely insane - every single update that you’ve pushed out has absolutely blown my mind!! Incredible work

When you showed the exaust noises getting lower when you made the pipes longer, I thought "Of course, this is how a trombone works." I dont know if it would come across, but I find the idea of the moveable bend of a trombone as part of some engines exaust hilarious. Maybe you can use that in some semi-serious testing. :D Edit: Also thank you for that "degenerate" part, thats totally my alley. lol

The sounds are def a massive improvement!

The fact he has beamng themselves as a patron is insane

Man every single time you make a video, you play it down and make it out as if it's not one of the coolest individual creations ever. The love you put into it shows through with just how good this sounds, and it's clear just how much work you put in. It sound absoutely insane and it's still a work in progress! I've heard worse audio on other videos of REAL CARS on KZfaq! If you blindfolded me and had me listen to @15:50 onward and a real exhaust camera (like gopro stuck above exhaust in supercar videos), I'd legitimately have a hard time telling you which one was real.

I was in awe when Doom came out with 2.5D graphics. Amazed when 3DFX cards appeared. Poor when I bought a direct drive force feedback wheel in 2011. Blown away by VR. This is the closest I've felt to those experiences for years!

This is the most mindblowing thing ive seen this year. Can't wait to see what it becomes in the future.

15:44 sounds like it's on an engine dyno and immediately makes me think of the Honda and Renault F1 V10 engine test videos! This sounds incredible and I cant wait to hear what you'll achieve at those higher cylinder numbers!

Sounds incredible, keep it up Ange!

The fact that I'm playing this video in the background and had to look over if a video of me on my busa was being played somewhere really says something about this program

The downshifts… this project is absolutely materializing into more than the expectations set by the earlier progress videos… and those videos set HIGH expectations. I love the comprehensive of this simulation, and the result is SO good

I've spent a lot of years riding 4 cylinder bikes, and I can't believe how real that sounds. Please tell me you're going to patent this tech. The automotive sector could use this technology to engineer exhaust systems, resonators, mufflers etc and rapidly iterate designs without committing to manufacture prototypes. I'm excited for you man. This is an amazing achievement.

This makes me very excited for whats to come. Well done Ange! ~AngleTheGrinder~

5:55 nice

the new sim sounds like a teal engine recorded on an old phone. That's super impressive!

12:20 I think it sounds pretty good, I think a part of the sound that's missing comes from the acoustics of the vibrating metal that an engine is generally made of

Absolutely amazing! I usually don't comment, but I want more people to see this

Wow! Your work is incredible!

What a huge update! One thing I can't wait to look forward to with the flow simulation idea exhaust tubing, I can 100% see this program being used by exhaust shops for pipe diameter, exhaust shape, tone and reverb!

The new engine sim is coming along nicely. Something I do want to mention is that all of the audio clips sound like recordings of a car from a distance. Perhaps it's missing intake and mechanical noises that you get when you're up close with an engine.

Looks awesome!

This is absolutely awesome! Well done! There’s so many practical applications for this!

You Sir. Are the best dev I have seen in a Long time. No AAA dev Team can keep up with the quality and attention to Detail. Much love from Germany

Sounds like you are on the right track! Really great progress!

16:15 I used to have an Acura CL Type S that actually had a similar type of resonance at part throttle at a certain rpm range, I think its all in the exhaust design.

Amazing progress, keep up the good work. Hoping to be able to use this to tune my 996 Carrera exhaust at some point...

WOW. this is such a drastic upgrade from the original. This sounds LIKE A CAR. beautiful.

Really cool to see that the team behind BeamNG is one of your supporters. I guess that means they intend to incorporate engine sim into their game in the future. THAT would be sick.

i hope this one day leads to a revoltion in racing games. realistic sound would truly be a game changer.

fwah 13:46 that had me going, that resonance makes it so real

Amazing job. The new simulation sounds amazing AND without processing (yet). Congratulations on this incredible work.

You’ve improved the simulation a ton, it sounds amazing and im super excited for this project to be finished, keeping going man.

soup approves

As an audio engineer, the output sounds bandwidth-limited. Keep in mind that to reproduce the full range of human hearing you need a sampling rate of DOUBLE the top end of our hearing range. We hear up to around 20kHz, so to be able to reproduce those frequencies we hear as “air” or “crispiness” your sample rate needs to be north of 40kHz. Common sample rates include 44.1kHz, 48kHz, 88.2kHz, and 96kHz. 96kHz is what I typically work at, as it allows for gentler, more transparent anti-aliasing filters during upsampling and resampling. I’m sure your computer sound card is running at 44.1kHz or 48kHz, but if your simulation is only generating data at 20kHz or so, the resulting audio can only reproduce up to 10kHz, which could explain why it sounds so muffled

This simulator just keeps getting better and better. That busa sounds REALLY good! The tone change with the pipe length sounds on point too. Keep up the awesome work man!

This is so good my guy, you just keep making it better and better. Love this.

Sounds absolutely fucking amazing! You’re a genious! I think the resonances that come from the tube simulations are what really make this sound real. Like when you added the muffler, it added a higher harmonic that changed the sound’s character greatly.

This is really coming along, and is sounding awesome at this stage can't wait for more!

That is a huge step up, well done. Exciting to see how this project develops.

Duuuude, it sounds so good! I'm friggin' impressed man

Dude that's sooooooo sick. Good job! I can't wait to see where you take this!

its really impressive how well everything works on this project. I'm eager to see what do you have to show us on the future.

This is so awesome! I am following your progress since the first engine video almost 1.5 years ago, and it is scary how close of a fully modular realistic sounding simulation you are today. If combustion engines really fade out of passenger vehicles in the future, this will be the greatest homage to them

the fact that the busa has the "wobbly" sound just makes it so much more amazing. if it was purely a sound test the vast majority of people wouldnt be able to tell the difference which is just fucking insane to me. very excited to see the direction this is going in.
