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.

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!

@@alexdandanalex this doesn't simulate the real sound in the slightest, or rather not the sound you would normally hear.

[@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.

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.

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.

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.

@@AngeTheGreat The video is awesome, gotta say that the EJ sounds pretty damn close to me. Thanks for sharing your work with the world!

[@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

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

[@tylermatthews9842]

Fantastic job. Cannot wait for part two and diesel engines. I recommended doing a Cummins 5.9L I6 vs Cummins 6.7 I6 in the last vid. Subbed.

[@spartanboss4189]

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

[@Dis-Emboweled]

The single cylinder honda ATV sounds exactly like my oooooooooold '81 Yamaha "exciter" 250 👍 Brought back some fun memories mate!

[@schoggi555]

omg this is amazing! id love to see forced induction in it too and a way to play around with exhaust lengths for each cylinder... great work!

[@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.

[@atlasultimate]

This is stunningly well made. I'd love to see a later release allowing for use of a racing sim's throttle/clutch/shifter to use in this program

[@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 ..

[@BatBeardGames]

This is the kind of thing that engineering students might tool around with in class or have a project to build an angine in it. I could easily see that happening. Glad your finishing this project.

[@Jack_Wolfe]

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

[@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.

[@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!

[@sjeses]

Very cool indeed. I can imagine a car building game procedurally generating a 3d model from the plans. Start your vehicle by building the kind of sound you want from it first, and getting an intuitive feel for mechanics along the way

[@abeidiot]

as a simracing fan, I must say I have been observing the audio of a lot of old games since I saw the first video in this channel

[@exemch4826]

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

[@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.

[@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!

[@judef]

Would be awesome if there was a similar program that creates an impulse response from a set of exhaust parameters

[@balkancommenterwithseveree7552]

I own a 4-stroke quad, and man that sounds spot on! Amazing job!

[@szlobi2276]

Amazing stuff, i have looked through the source codey its fascinating to see how all the components work together.

[@appuser]

Genuinely haven't been more inspired by a piece of software in as long as I can remember.

[@AruEsse]

You got me with the Audi, it's so accurate. As much as I hate this I am sure this kind of tech will find it's way into production cars to enhance and/or replace the engine sound

[@bbt3395]

My dad had an Audi 80 with this particular engine for more than a decade, I've driven it so many times I would recognize the engine sound with closed eyes. The sound generated here is quite similar but it's definitely not the same as the real deal.

[@Alan_Hans__]

That simulation engine is incredible. The sound that the Hayabusa makes is next level compared to any of the others.

[@Sebastian-hc8rj]

i love how you can see the overheadcam change in the vtec

[@CturiX.IREALLY]

I'd like to see what the team from Automation thinks of this. The possibilities from integration with this would be impeccable

[@mla_bdn8269]

It would be interesting to see how this simulator handles diesels like the z17dth from opel or 1.9 tdi from vw, especially since the ignition method is different and all that jazz

[@MAxAMILLIoN757]

I'd love to hear the 1.9 TDI 😯

[@xlime6139]

Can't wait to test Yamz 238 and SW400 Andoria-Leyland

[@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!

[@alexhill7305]

This is absolutely mindblowing work

[@Leftysrev3nge]

Please license this for game developers. Stupendous work!

[@KohiBureiku]

AH The radial engine sounded soo good at idle! However, when revving up it started to sounded like a car engine at that point. But it was nice to see that you tried to do a radial engine! Hopefully, this can become something more in the future!

[@Kixuf12]

Its probably because a lot of noise comes from the prop when you spin up an airplane engine

[@KohiBureiku]

@@Kixuf12 True, but I'm just probably just used to hearing a Sherman tank with a radial engine. That has a unique sound of its own. :D

[@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.

[@JulianSauco]

You should implement xinput or some sort of controller support in order to have more gradual control for the clutch and gas pedal!

[@tauon_]

apparently he re-open-sourced it so I was going to add SDL_Gamepad support to it

[@glenngray6895]

The comments I read are entirely accurate! You really do have something here! The reason I'm looking and you have it closer than anyone.... I'm looking for a tuning tool with approximate outputs with given information. I dabbled in programming many many years ago and I KNOW it would be a serious amount of additional programming to get where I want to go. This program/app would be something that would sell to high performance engine shops engine enthusiast and gamers with technical knowledge.

[@bufftheowl]

I'm a huge fan of cinema and simulators and have my own F1 simulator cockpit and during learning everything I know about cinema I heard an interview with Danny Boyle and I've never forgotten what he said which was "movies are 60 percent sound and 40 percent picture". I think he's right, you can have a bad image with great sound and it still be OK, but not really so much the other way round and I think this is also true to simulators. So in summation, there's nothing this sim and cine phile would love more than for people like you to change things in game development industry as much as I think you could. I've never subscribed on Patrion, but you could be my first.

[@schell9726]

Awesome engine simulator, love the sounds. Only thing I don't understand are the gear ratios or the car's drag, feels like I'm on a 20% incline.

[@edd4816]

That shovelhead sounds remarkably like the real thing, what a truly amazing simulation. I wonder if you might be able to simulate a moto guzzi v7 engine, just because that's my bike and I'm curious if I'd recognise it :3

[@generic7916]

Absolutely amazing work! But it does make me wonder how a marine 14 cylinder would sound... But more reasonably a Honda cbx motor could be great

[@RainytheNB]

One thing to note about Harley engines is that they always spark on BOTH cylinders at once, which causes unburnt fuel/air in the exhaust to ignite giving the exhaust stroke a random chance of having a "pop" sound. You should totally code that in!

[@glenngray6895]

Dude you are awesome for doing this with such a technical angle!

[@no-damn-alias]

With such a tool I'd be curious about an engine that never existed. A 7 cylinder inline engine.

[@MrGallade475]

Inline 7s see limited use in ships and farm equipment.

[@no-damn-alias]

@@MrGallade475 yes and I'm curios how it would sound at higher rpm as a petrol engine

[@idowhatiwant3451]

Or V14 engine.

[@nthgth]

Or maybe a V-8 with 5 cylinders on one side and 3 on the other. Why not.

[@no-damn-alias]

@@nthgth well I don't get that but hell why not
