Thanks for watching everyone! By the way, I've received literally hundreds of comments and DMs asking very basic questions that are already answered in the FAQ which is linked in the main GitHub page. As I stated in the video, this is not a game and was not intended for public use so you'll need to lower your expectations a little. If you want to support this project and get it to a point of being that amazing game that you envision, please consider supporting my Patreon. If you don't like paying for things, you can always modify the code yourself to make it do all the things that you're asking for. Whatever you choose, let's all be respectful. Stay classy guys ✌

Hi, Sorry to bother you but if you don't mind answering... I would want to know how in which file I can adjust the throttle position/speed control setting for every wheel scroll. Mine (if not everybody else's) is 0.012 per wheel scroll. now I don't know if it's parametered this way because it's windows's base value or the one you deliberately set it to. also, would also appreciate the file where we can set keybinds. Sincerely.

The reason the Subaru didn't sound as close to its real life counterpart as the other engines did is due to the fact its trademark engine sound comes from its unequal size headers, resulting in the order in which we hear each cilinder to be different from its actual firing order. Im sure if you manage to figure this out you'll get the classic deep rumble we associate with their boxer 4 cilinder engines.

Although it wouldn't quite sound like the real thing (then again, recording all the nuances of the real thing is hard considering how loud it all is), what really piques my interest is the sounds of impractical or impossible engines. It's one thing to have a model of a real engine that won't constantly clip your microphones while recording it, but it's another to have a model of an engine that nobody would bother machining or would explode as soon as you turned the throttle too high!

[@Archimedes.5000]

@@alexdandanalex this doesn't simulate the real sound in the slightest, or rather not the sound you would normally hear. All this is useful for is for calculating frequencies of the explosions, but this tool is an overkill for that, and the more important thing when making realistic sounds are the acoustics of the surroundings (what the sound passes through, rather than what produces it)

[@The_Mister_E]

@@Archimedes.5000 There's cabinet simulations and (most importantly) impulse responses for all sorts of containers. And making an impulse response for... well... anything is just a matter of playing a few sound files inside whatever you're modeling and using microphones to capture what leaks out. Engines are very complex sources of sound, full of moving parts and propulsion. You can model the inside of an engine block and maybe the individual processes of an engine, but you can't really model all the sounds of an engine and how they influence each other without modeling the entire engine.

it would probably need a bit of tweaking due to those engine nature, especially in the more modern ones (for example, at high RPMs its believed the spark plug is not even needed and those self ignite) Also: the more modern ones have a charachteristic faster combustion due to the pre combustion chamber spraying ignited fuel in the chamber. Probably would be also required to simulate variable geometry "trumpets" intake and a different internal friction coefficient. plus on high performance engines the exhaust system is designed so that the exhaust gasses create a slight depression behind them so that they "pull" the exhaust from otehr cylinders. All of this would probably require some particular tweaking... and probably there is even more. But would definitely be cool as hell!

[@750kv8]

The clunking idle sound is the characteristic diesel sound when it's not fully warmed up yet, and the fuel mixture doesn't burn uniformly across its volume. Strictly speaking it's not a mechanical noise, and the current simulation won't be able to pull this trick yet, as it only seems to simulate uniform combustion. (It does not simulate actual mechanical sounds, only aerodynamic sounds created in the exhaust valves.)

[@OptimusRhymeCrew]

Really, really awesome work! Well done! Anyway, as a professional audio engineer i can think of some improvements: As far as i can tell, you are only using one sound sample, shaped to liking. Its some noise that you tweaked to fit. You also mentioned that you had to eq the thing in the last video because the sound would otherwise be to muffled (which i still think is the case.) So in order to get it naturally right, i suggest two things: 1. The real sound is a mix from ignition spark, then explosion and then the exhaust gas. Since we have a very high frequency of ignitions, most of the low end from the ignition spark and explosion will be cancelled. But the transients of the initial combustion will give you the top end of frequencies that will make the sound realistic (and probably somewhat brutal). 2. No sound is the same. Our ears do recognize this very quickly and get used to it. We get bored, it sounds artificial. In order to get realism we use a technique called "round robin samples" those are slightly different samples thrown in at random to keep some variation. 3-4 different samples of each sample in the composition will do the trick. (3.Bonus: Different volumes have different resonant sounds, too ;) ) You should think of monetizing this. Its too great of a work to be "just for fun". First thing coming to my mind is BeamNg Drive which would be a blast if this could be implemented. I would love to see this in game. Second thing would be a VST Instrument to plugin to DAWs for realistic engine sounds. A gamechanger for Audio-Engineers working with car sounds from games to movies or sth. Hope you consider pushing this forward, i am stoked! - love, Freddy

As both a software engineer and engine lover, I really appreciate this.

[@hyperbomb02]

Absolutely stunning work.

[@ChickentNug]

I was hoping you'd do a radial one. Thanks for the video!

[@SaltySRT]

How about an inline 7, 9 & 11 (ships are weird like that)? Interesting how those things might sound with car sized bore/stroke.

[@billbergen9169]

12000rpm I12? Yes please!

[@biggonuke]

i’ve always wanted to hear 7 cylinders, hopefully he does it

[@calvinl5661]

Now i really want to see a simulation of an actual ship engine like the RTA96C displacing over 1800 liters per cylinder.

[@sharcc2511]

@@billbergen9169 More like 1,200 rpm if it's a boat engine, lol

[@PeterPeh]

same for me, alwas wondered what a straight 7 would sound like!!

[@tilen3266]

Suggestion: one thing that would be quite cool is if you could use a steering wheels pedals and shifter (example, logitecg G920) to controll the clutch throttle and gear of the vehicle simulation

[@procrastimate1956]

I thought the exact same thing

[@first_last01]

[@qasprrr6203]

100%

[@sarowie]

that would be very funny - and to make it more fun: retro graphic car simulator

[@raulgalets]

for sure. he doesnt even need the steering wheels, he can get only the pedals

[@MetalWarrior223]

this is absolutely insane!! the potential of this tool is crazy! An absolute game changer in my opinion

[@dhoffnun]

This absolutely blows my mind, and very much raises the bar.

[@EthanDean57]

As far as 1:28, is there/will there be support for digital and analogue inputs? I'm not joking, I'll sit there with sim racing pedals and a shifter all day with this.

[@sarowie]

virtual fuel economy simulator

[@tauon_]

I might add gamepad support if it’s open source again so if it appears like a regular gamepad then yes

[@spartanboss4189]

You can actually see the lobes change on the Vtech engine, that’s awesome

[@gupymusic1199]

This is nothing short of INSAINE! I never imagined in my lifetime software could accurately re-crate engine sounds perfectly. BRAVO!

[@tristenboatman8581]

You've just gained another subscriber. This is so damn cool to mess with.

[@captainslow2883]

Can’t wait to see how far this goes with different valve types, fuel types, and other electronic bits

[@shadowboy813]

Fuel types won't change the sound of an engine by much. The sound is dictated by pressure pulses from intake and exhaust. In fact, under deceleration, modern cars shut off the injectors. While engine braking, modern engines use no fuel at all.

[@nthgth]

​@@shadowboy813 I thought that, but this simulator shows fuel consumption happening even while coasting. I believe you're right though, and it's just a minor oversight in the code.

[@the_thornhill]

man I could spend all night just revving those car engines, this 'game' is so cool! Amazing work my man!

[@FilterYT]

I think you did a beautiful job there. Pretty cool.

[@SAKIBALTAF]

we need this to be turned into a beginner friendly software or a game perhaps... hats off to you for this awesome piece of engineering ..

[@Jack_Wolfe]

I love the frequency shapes, it reminds me of those rules for animation, where every looping motion is some weird circle.

[@herbertpocket8855]

Oh man that was cool! Love the stats

[@subpoena.]

You should add a muffler system that you can physically see reacting to engine vibration and modifying the sound, visual exhaust even going through it could be badass. On a more difficult note, a 2 stroke engine would be mighty impressive.

[@yngfljm2277]

yes plsss @angethegreat, also if you see this, when you slowed down the animation, are we hearing the explosions or exhaust sound (as in exhaust gasses leaving the combustion chamber), or are they one in the same? I've wanted to know this for years now as I could never quite formulate my question until now. I originally thought of it when I would watch cold-start videos lol and wonder when the rpm is below 1000, you could hear the individual sounds of the engine, but what exactly are we hearing? Thanks I hope I made any sense :(

[@zackfletch00]

This is awesome work, definitely worth a sub! Love the inclusion of the 5 cyl Audi, and I’d love to hear it with the addition of a turbo and higher redline. Can’t wait for more!

[@Drosba]

It would be cool to hear the intake sound too. Or even unique sounds like the one the hondas produced with their gear system for the cbr250rr.

[@wizardbones7159]

Incredible almost hearing a mower engaging its blades as the engine takes on a load

[@Sadjina]

I love your stuff, please keep it coming!

[@exemch4826]

So cool, i hope the future of virtual racing will impliment something like this, that 5 cyl sounds incredibly accurate

[@Psyconinja1532]

This is so cool. As someone who loves cars, engineering, and computers, this hits all the right spots. Have you figured out modeling forced induction my any chance? What's the likelihood of being able to model rotary engines? Love the videos, keep up the great work brother!

[@paisley4092]

this could be a great way to learn to diagnose a broken system in an engine. i really hope this takes off and becomes a way for educators to teach car mechanics

[@AyyyGabagool]

looking forward to future of this sim!!!!!

[@trulyinfamous]

This is still blowing my mind. I eagerly await any new content you make as I was immediately hooked with the last video. To test the limits of your sim, you should try the Pratt & Whitney R-2800 Double Wasp; a 2000hp, 18-cylinder beast of an engine used in American fighters back in WW2.

[@KomradZX1989]

This is so kickass dude. I’d pay for a polished version of this in a heartbeat. I’d even pay for an unpolished one! Off to Patreon!

[@frogery]

dude this is honestly one of the coolest things i've seen

[@nickmudd]

I love that you got the rev limiters too, AND they sound good!

[@Kodagraphy]

This is so unbelievably cool The sounds may not be perfect, but hearing that Honda ATV engine gave me super nostalgic vibes I haven't had in a good 15 years since I last rode ATVs with my family. 10/10, even for a product still in development.

[@Fasteroid]

Amazing work! I'm no engine aficionado, but I instantly recognized the Harley bike. That one sounded great! For part 2, you should consider showing the real-life equivalents before showing the simulated ones. It'd help people like me with less engine knowledge appreciate the accuracy of the simulated sounds more. Anyhow, amazing work, keep it up! People like you are the future.

[@brothermarten]

You two-stepping a simulation scratches the back of my brain so good.

[@rundllx3228]

You can really be proud of yourself. This is by far the coolest thing I've seen in a long time

[@HanZie82]

Oh snap the sounds are pretty damn amazing. If those come from just the cylinder being in a certain spot. Kudos to yah.
