This is really good!
This is truly music to my ears!
Add buttons for people on mobile?
Even better, use the gyroscope.
hmm, I either don't know how to use it or it doesn't work in Safari
Reload. Click in the window. Then rev up the engine. It breaks when you switch sounds -- so reload, select sound, click somewhere, etc.
Tapping on the controls is broken. Typed text in gear number field is erased immediately.

The app sounds fun. Excited to try it again later.

Very cool, get to top RPM in gear 6 and drop down to gear 1 for an ear-rending shriek.

This would be great to load up onto an RPi and put into a kids toy. Maybe use it to pimp up one of those toddler steering wheel sets.
^^ This.

I thought the same thing. I want to rig up a optical encoder to a bicycle tire and use the output to drive the engine simulator - make my bicycle sound like a sports car.

Way overengineered... Back in my day we were happy with sticking a plastic bottle between the tire and frame :)

Looks like kids still do it today: https://www.youtube.com/watch?v=OWRv17qvM0s

Granted, but can a plastic bottle be modified to make my bike sound like a Star Wars speeder bike?
Why turn your kid into a degenerate before they've even reached adolescence?
The car sounds add to the experience of playing with a steering wheel, versus some tinny soundbox?
Fun! Would be funner if it handled the money shift.
If you liked this, y'all owe it to yourselves to checkout AngeTheGreat's channel. It's truly amazing work.

Yeah, I always look forward to their new developments. This is similar to Ange's effort with SiliconX to add realistic engine sounds to an electric motorcycle though this appears to be for an electric race car.
For a less scientific approach LAxemann has some interesting videos as well. He uses software synthesizers to create the sounds. His introductory video is quite interesting:

He has other examples and updates on his channel as well.

That rigid body engine sim is, without a doubt, one of the coolest software projects I’ve seen in my entire life. If only we could get sim racers to adopt this tech.
Ange's top patron is BeamNG, arguably the most physically accurate sim racer out there right now (in some areas, it still needs improvement). I predict within five years BeamNG + engine sim will leapfrog what anyone else has done in this area and recreated what we all thought video games were doing when we were little kids.
This is amazing. I think a small amount of window dressing would make this a classic page people bookmark and return to frequently just for fun. Especially if that make it mobile friendly.

Like even just two pedals and two flappy shifters on screen with all those other tools hidden behind a collapse or whatnot.

If you downshift with RPM too high, UI breaks off and falls to floor of screen

Whole Page turns red when you hit RPM limit

Shift score. Can you pick the perfect shift point based on sound alone?

Tangentially: Does anyone know where to find a collection of the low speed sounds emitted by electric vehicles (in the US at least)? I'd be interest to hear the different approach different manufacturers have taken.
i too would be very interested in this! i am for now a petrol head but continue to be fascinated and also mildly irked by the varying EV sounds.

some sound like galactic spaceships, some like weapons, some like "blurred mechanical noise", and some are almost indescribable in words. some can be semi-nightmarish.

i'd love to play with a soundboard that had all the different EV manuf sounds on it.

Shortly after moving into my current place, I would randomly hear this hum that for the life of me I could not figure out what it was. I had even looked at maps to look for some sort of place nearby that might make sense. It wasn't a constant hum, and there was seemingly no schedule for it. A week ago, I just happened to be in my drive way instead of the fenced backyard when I heard the noise. It was my neighbor's EV <facepalm>
There was a short moment when I thought the future looked like no fumes and no noise (well, at least no engine noise; tires are quite loud at speed). And then the government decided that EVs should not be quieter than ICEVs, in fact they should be louder. And some of the hybrids on the roads (looking at you, Toyota) are the loudest of them all.

Different strategies for different cars, though.

My neighbor's Highlander hybrid is audible a couple blocks away as it comes into the neighborhood.

Our old Bolt EV was not quite as loud, but still distinctive and never a surprise to anyone as it came down the street.

My Model 3, however, makes a white noise sound going forward that you don't really notice aside from very low (single digit) speeds in a very quiet environment. But in reverse, it howls pretty loudly, and is probably louder than any of the hybrids.

I absolutely love the reverse sound my Toyota RAV4 Prime (hybrid) makes: https://www.youtube.com/watch?v=gUT94MBt_Ao To me, it sounds like the future. Sort of a hovering UFO. People's heads definitely turn when I back out of my driveway.

When I first got a RAV-4 hybrid, I had no idea that this sound was being pumped out of a speaker. I thought it was an artifact of the electric motor. As it happens, companies spend a lot of time designing their unique electronic sound as a signature of the vehicle. My dog has learned to recognize the sound and he barks when the car is as much as 1km away.
I think you’re the only one.

I wouldn’t mind as much if the volume wasn’t 5 times louder in reverse than drive.

Let me make sure I've got this right... According to the video, if the driver of a Toyota EV reverses through a "cross walk", and hits a pedestrian, it's the pedestrian's fault for not getting out of the way?

And, in order to prove that it must be the pedestrian's fault for not noticing the vehicle reversing through said cross walk, the vehicle omits an obnoxious noise at high volume?

I didn't watch the video, but both practically and legally speaking, in the US when a car hits a pedestrian it's considered the car driver's fault, excepting some circumstances. The noise doesn't have anything to do with it- cars have to stop for pedestrians in marked crosswalks, and should stop at any formally defined crosswalk (not all "crosswalks" are directly labelled or signed as such).
My main objection to the newer EV sounds is that they are tonal enough to be recognized as a musical chord, but not a pleasant one. It’s either vaguely minor like a horror movie score, or a downright dissonant mash of pure sines.
> semi-nightmarish

There's one I hear regularly that sounds like a choir of demons.

Is it the Honda hybrid sound? I owned two hybrid CR-Vs (loved those cars, but got into an accident one year ago today that totaled a three month-old CR-V hybrid and car prices went up so fast we had to downgrade). We always called it "Hell Choir". It makes for an amusing contrast to the horn, which sounds like a clown car.

I’m not going electric unless I can choose the Hampsterdance as my motor sound.
I really hope we can get to a point where there are multiple approved sounds to choose from. If the car has to make noise, might as well be able to select from some options.

Probably won't see Hampster Dance approved, however...

On the one hand, yes!

But more realistically, think of the headache of trying to keep your engine's Hampsterdance in sync with the Hampsterdance blaring from your car's stereo, (as it naturally would be).

Not to mention all the other excellent tracks on https://en.m.wikipedia.org/wiki/Hampsterdance:_The_Album

God, the Hyundai sounds are terrible in Korea. They sound like a UFO and are very loud. They tried to go too hard with the future vibe and it drives me nuts living in the small streets of a very busy Seoul.

Oh my god it actually sounds like a more high pitched version of the Jetsons https://www.youtube.com/watch?v=4NgSZ8sjDgU

Edit: Found it, look how loud this shit is! https://www.youtube.com/watch?v=IgvUu2YZ5ps

Having a loud/annoying low-speed sound would be a dealbreaker for any EV purchase.
That's the thing. When you're driving you most likely can't even hear it unless it's dead quiet (and when it's dead quiet these things don't adjust, they are LOUD).
I did notice this when I had a city apartment with a window facing the street: regulators have not taken noise pollution into consideration. They made it very loud so as to be sure to alert all pedestrians, which is good, but it is also far more noticeable than a quiet ICE in several situations. If I’m in a building, I really do not want to hear a vehicle! Noise pollution is a real problem and the current regulations unfortunately do step backwards in my opinion.
It will happen eventually... hopefully. I'm usually ahead on my complaints to the average Joe. So since I started complaining a couple years ago I give it til next year to start being enforced.
Holy crap, is that modified or do they all sound that loud? And not just in reverse? Not the future we were promised.
They all sound like this (the newer models obviously, probably as far back as 2020)

I'm sure there's a way to hack it and turn it off... but who's going to do that?

Absolutely delightful!

This is way more fun than it has any right to be.

Anyone know good tutorials for simulating drone/airplane propeller sound?
That would be an awesome PsyOps sound to get people looking in the wrong direction
This is a scary but incredible idea.
It'd probably much cheaper just to fly a set of drones in the area rather than deploy a full PsyOps team and gear. They do it with actual jets while the actual attackers are flying in fast and low from the opposite direction now that you've sortied your defensive aircraft towards the bait.
wow, most of the time the engine sounds of cars designed to go 0-100 quickly sounds super generic, but this i can actually get to sound like two different cars i've owned. I could almost get it to sound like a Lancer Evo X but there's no blowoff or turbo sound... maybe in the next version!
Pretty cool!

Downshifting under braking doesn't feel accurate. Most fast cars brake like 2-4x their acceleration rate, but in this sim, the braking feels more like 100x.

The sound of an engine under decel is just as awesome as acceleration.

Deceleration is where you get fuel overrun and backfires, too!

    VrOOOOooomm-pa-pop-pow-ooooom.
Slightly off-topic, but I hate when people modify their engine / exhaust system to do this on purpose, just to be obnoxious. You're not cool, dude. You're just a jerk.

No, this is 100% on point. I support your comment and it isn't off topic at all.

They are certainly cunts and it would be amazing if police actually enforced noise ordinances for passenger vehicles at some point. Fingers crossed! As always!!

Both of my cars are stock and are like fireworks going off if I lift off the throttle. So this isn't just a modified car thing, a lot of cars made in the last 10 years pop, bang, and fart from the factory.

If police started ticketing me, I'd probably just sell the cars since tuning either car is a pain in the ass (locked ECUs). Granted, police are already ticketing people with stock exhaust.

> Both of my cars are stock and are like fireworks going off if I lift off the throttle. So this isn't just a modified car thing, a lot of cars made in the last 10 years pop, bang, and fart from the factory.

That's fine, happens in a lot of performance vehicles. Some people just do stupid stuff to artificially increase the amount of noise. Some of it is illegal (like removing the muffler) and some of it is just rude (like setting the air-fuel ratio to be far too fuel-rich). Some engines are naturally a bit fuel-rich, especially performance engines, but some people just change it to be as loud as possible.

This is great!

For a game I was making years ago, I tried to make a “crowd noise” generator. As in for a football/soccer match.

But it was not my skillset and I failed miserably.

Does anyone know of something that might get me started?

A non-procedural approach might be easier: collect loops of baseline murmurs / elevated cheering / peak ecstatic crowd and vary the volume of each based on what is happening on screen. If you have variants of each "energy level" you can also smoothly fade between them, queuing the next one randomly as the current version runs out. This way the wrap-around point should not be that noticeable.

Something similar is done for music that varies according to gameplay intensity: https://en.wikipedia.org/wiki/Adaptive_music

More fun than I expected. Now I want more engine sounds. I wonder how hard it would be to contribute new engine models. Like, what is the recording process and processing required to build the source sounds.
I touch Theta param in the left part of it, and the sound disappears, all the numbers go mad into infinity and then become NaN. Also there's no sound if none is selected in controls, but changing anything in controls makes the same effect -- all params spiral into infinity. Not fun.
I’ve got one of these. It’s called a toddler.
I've also got one. It's called my jackass neighbor.
