@@Iliedavidrealchannel if you mess with the exhaust piping in your car and separate the tubes for each cylinder you can make it sound amazing. this simulation shoes why things like a Bugatti spend so much time and money on that

[@arielfernandez8196]

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

[@luuk341]

For sure! Older Japanese bikes with indivudual pipes for each cylinder do exactly the same thing! I actually LOVE it when they sound like that. CBX 1000 does it as well

[@kasuraga]

It honestly makes the simulator more impressive to me because it can take those sort of design flaws into consideration and accurately reproduce them

[@MichalKobuszewski]

I wonder how much of the actual exhaust system behaviour could have been predicted at that time during the design phase. It sounds like the beating between the pipe resonance frequency and the actual exhaust gas pulses might affect the engine by periodically aiding or impairing the scavenging (just a wild guess). Aside from reducing the Q of the pipe to "spread" the resonance, could this be controlled somehow? Perhaps mixing in the pressure wave from another cylinder is enough?

[@alobowithadhd6191]

I was going to comment on this as well, I was especially impressed because that is a sound I’ve not heard in a long time. This makes me want to spend money I don’t have just to access the patron content. (Why I stick to Steam.) Edit: Autocomplete thought “Steam” was “Stream.” Fixed.

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!

[@squareeyes1117]

It really is some amazing work and a huge leap from before.

[@233kosta]

This is one of those things that, if you know what's actually going on, feels criminally oversimplified as a model. It never had any right to sound remotely plausible at all. But as more fidelity gets added over time, it'll get closer and closer, until at some point it becomes indistinguishable from recorded sounds of the real thing. I wouldn't be surprised if at some stage this becomes mature enough to be picked up by the engineering teams working on real engines as a first pass to weed out the silliest ideas before any real CFD gets done.

[@upsurge5541]

@@233kosta i would say it already sounds better then recorded sounds coz of the compression and shit most games have mid audio

[@ceremyjlarkson9475]

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

[@themonsterodub]

I haven't heard of this phenomenon before, but I know in my NA 2.0l focus, there's a noticeable shift in tone between 3-4k rpm and it changes in almost exactly the same way as the simulation. Sounds throatier, almost like there's a lower octave that creeps in and out as you go through the rpms. Again not sure of the mechanics of it, but it seems the simulation matches reality.

[@ceremyjlarkson9475]

@@themonsterodub I'm not entirely sure if that is exactly the case either. Going off of memory, when the air is being compressed by the piston going up in the exhaust stroke (this increases the pressure in the exhaust) there's a return shockwave that can constructively interfere with the exhaust air that is being expelled. I am curious if that is indeed how it works but I wouldn't be surprised if it was some other mechanism

[@reeseferrell2731]

@@themonsterodub In that part of the simulation he's using 4 individual pipes, in a real car the individual header tubes would link together somewhere in order to help pull the exhaust gasses along using scavenging. This also somewhat reduces audible resonance, but if you listen to single cylinder engines or v-twins with 2 exhaust pipes you will sometimes get bizarre resonance out the exhaust.

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!

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!!!!

[@joshjlmgproductions3313]

That kind of resonance is usually cancelled-out by exhaust mergers, if it exists at all. There are NVH factors in real vehicles, but the one in the sim sounds a bit odd.

[@jesuscontreras2626]

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

Just imagine what that would cost if you have multiple cars running the same simulation.

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.

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.

[@exstacc1886]

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

[@logtrimmer]

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.

[@Spectra1351]

He did say not supported YET! So it is a feature he is going to implement. But what you have mentionned is true engin sound does matter depending on the exhaust configuration, just search up x pipe vs h pipe that already makes a big difference in sound depending on the car.

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

[@ralekriver]

@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"!

Andre just like unequal length changes the sound, if we do an inline 6 with a 6-2-1 header (two collectors one for each pair of 3 cylinders), instead of a 6-1 header (single large collector) would the new engine simulator be able to produce a completely different sound profile? Since in real life I’ve tested both those header designs on an inline 6 with the same exact exhaust after the collector and it sounded completely different.

5:55 nice

[@Roy-K]

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

[@Mellonote]

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

[@jhoni_48hz95]

Yeah, sound so real

[@johnfreeman2956]

@17:50 yes this is the content I like. I am eagerly waiting to see how your simulator runs a hit and miss engine

[@stuartclark4045]

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

[@tomisuikkari992]

Just WOW, the sound is really close to an open header, larger 4-cyl bike, especially the immediate off-throttle sound amazed me.

[@Creesic]

Wow! Your work is incredible!

[@teenageapple3788]

If it's possible. It would be so awesome if we could somehow "render" the audio produced so we can create entirely unique engine sounds for as an example, a racing game with uniquely designed cars

[@lettuce7378]

That Hayabusa motor sounds 👌

[@TheRumpletiltskin]

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

[@miggyo.2235]

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