Thanks for watching! - Zábava
One thing that I should have emphasized more in this video is how little effort it took to get semi-decent audio out of this simulation compared to the original Engine Simulator. I know the results might seem a bit underwhelming right now but don't worry, this is not the final version. Thanks for watching guys 🙏
This is still some incredible stuff can’t wait to see what’s next for this project
The potential is huge on this concept, and I wish you all the luck
Is there any chance this could also revolutionize gunshot sound synthesis for indie devs to no longer require expensive AAA tool licenses?
Wait, how much do you have to donate to get on the lost?
The evolution of this utility is fascinating! I hope to one day use this to develop more exotic sounding exhaust notes for conventional engines. A little flare for those odd swaps. First target is a GM LV3 6 cylinder swapped into a Porsche Cayman...how do we make that sound more like a Porsche and less like a GM vehicle! Kudos!
I was blown away by this. The siren howl actually sounds like air moving. WTF
Air raid alarms are usually rotary things that work on very high RPM, so their howl is in fact air moving at insane speed.
@@achannel7553 All animals are sentient by definition. Did you mean sapient or concious?
@@theStumblinbearmost animals also hear things
@@achannel7553to be fair, I think a lot of native speakers don’t know the difference between sentience and sapience
“ _blown_ away” by moving air? heh
"I get lots of emails from siren enthusiasts" is not something I expected to hear today. It sounds amazing!
I guess Siren-Simulator for 5 bucks has the potential to fund this channel for years.
Don't make the same mistake I did. I looked up what the three mile sirens were since I grew up in the area, to which I learned they were ACA P-10 Penetrators which were later replaced by the ASC T-128, and from there I learned my local fire department had a Federal Signal STL-10, and then I slipped on down the rabbit hole of emergency siren history. We've made a LOOOOOOT of different sirens over the years. You can get lost in the Air Raid Siren wiki for hours reading up and listening to different makes and models.
The SiraTone EOWS 612 being commanded to play Alternate Wail is the freakiest alert pattern I've ever heard.
'We' won the soccer world cup some years ago. One of the highlights this evening (aside from the parties everywhere) was a seemingly ancient air raid siren. Everybody needed to have a spin, literally.
I'm not surprised there are siren enthusiasts out there.
@@FurryWrecker911 oh god time for a new autistic hyperfixation for me, it's gonna be even worse since i'm an EMT and work with sirens all day 💀
@@literalantifaterrorist4673 Welcome to the Hyperfixation club. This week Sirens.
No fr tho I got hyperfixated on Sirens for like a months straight then poof. it was gone.
Dude that siren sound made my jaw drop. It sounded EXACTLY like an air raid/tornado siren.
All sirens are at the end of the day is a fan blade in a box, at least they were until we swapped them out for speakers in recent years. Sound is just air being displaced at an inconceivable rate. It's pretty nutty. For another mind blowing-experience, look up rotary subwoofers. >:D
13:30 Law & Order theme song ending 🤣
I actually find that the reverb takes away from being able to clearly hear the engine, especially since most engines are listened to outside where reverb is minimal.
Lol, if you live in a city, or in a forested housing area such as myself, all you get is reverb all day every day
@@LeGrandSarrazinNot at this intensity. At level presented it was more akin to running the negine in a garge or workshop. Granted, it's probably very easy to just have a control for this so its simple to have a slider in UI for amount of effect.
@@gloowaczfunny thing, the place where i live has some streets that have exactly the kind of reverb i heard in the video - to the point that it startled me how accurate it sounded even with such a "crude" approximation. but it it true that most streets do not produce quite as much reverb
The reverb sounds like it's in a parking lot.
@@wulfifi@halluminium Maybe i'm just too used to my city. It's very "green" - there is tons of noise supressing foliage growing everywhere, bushes and trees on every street, etc etc (often placed in between every few parking spaces in malls etc) so maybe my perception is skewed, but that does not sound like anything i have ever heard on the street or parking lot. It was like it was placed in a corrugated sheet metal room, where the walls would actually resonate and increase reverb.
For a one-cylinder engine, those sounds were actually almost perfect, siren was crazy accurate too
sounda like a ktm duke 125 or yamaha yzf r125
@@z3shan989 that somehow turns into a royal enfield bullet 350 while idling
agreed, it almost sounded like a midsize RC airplane motor with an unrealistically low idle speed
I love how he keeps saying "we" like any of us have the skill or the originality
I for one applaud our upcomming vrum vrum toob overlords' progress
HAHAHA I was thinking how cool this update was, but then the air raid siren just cracked me up!! I love it!
"A 270 page document... ...that's surprisingly detailed."
Is like saying, the 200 kiloton explosion, was surprisingly loud.
I'm imagining a car builder where you can tune suspension, tune a virtual ECU, swap out parts, etc. Like beaming + automation, but focused not only on realistic simulation of pre-defined components, but also fine-grained creation and editing of parts to design a truly bespoke virtual car that handles, drives, and sounds exactly how you want
Messing with fuel maps will be both exciting and stupid annoying
@@GewelRealyeah but imagine what one person could learn just from playing around with it, then BOOM land a job at a speed shop with vidyagaem knowledge
I imagine the same thing, and I can’t wait to see if someone can build it in the future! I want it lol
So has literally everyone else since video games were a thing
A consumer/hobbyist level simulation (not necessarily very gamified but like a virtual engine dyno) would be incredibly useful for R&D when building real engines... I'm always wondering how a change might affect the whole but without simulation or money to throw into testing IRL, it's difficult.
“Smaller video than usual” what!! Dude every video from you with progress at all is HUGE, don’t worry about it. This is going to change the entire gaming world forever.
Sounding great, by the time you were done it sounded exactly like a one cylinder engine, like a 2 stroke. That’s a win. Siren is also very cool, and I’m also just really happy to hear that there is such a thing as a siren enthusiast, and it’s so cool they’ve reached out to you.
The siren was great.
Also excited that there is a siren enthusiast community
definitely worth $20 a month to see this a day early
But you need to wait the same amount of time as without 20$?
@@shadow_blader192 Just let him spend his money how he wants to :p
@@supersaj1536because he is a sponsor
@@shadow_blader192I was confused what u meant lol but I get you
@erenbaltal9669 thanks for writing XD
Always love when Ange says, add a bit of convolution reverb and then adds tons of reverb haha
Sounds like using the item in an empty school gym
God this shit is so cool. It really helps give an understanding of how these physical properties all interact. With games and tools like these it's going to actually help people model and prototype things that would previously take CAD and expensive fluid sims to do In a way that makes sense for the project car peeps
The ability of engineers to find practical ways to model the world is mindblowing. My favourite thing about Ange's work here is his ability to abstract known processes to their core, and couple them in a complete system. To do so in realtime demonstrates and extremely impressive intuition for reality.
Physics simulations like this scratches a juicy itch in my brain, every time. If this project comes to life as a game, it will be the minecraft of car building games.
If this can run on separate threads then for Beamng this would be awesome. Stock car sounds aren't that good and realistic physics need realistic sounds.
Sounds like the leaf blowers outside my window at 8am 😂 awesome work.
You should simulate a 4-chamber human heart - that exhaust vs pressure graph reminds me of a QRST heart graph with pressure of heart chambers
Get a lub dub
The siren made me smile as a minor siren enthusiast. Gotta love some Thunderbolt T-1000 wail.
"...people don't usually run engines inside audio studios..." ...
... *starts engine in bathroom*
To be fair, more engines have probably been run in bathrooms compared to audio studios
Before adding the noise function, it was a perfectly adequate weed-wacker/leafblower simulator.
thats what i was thinking. for how small the engine was it felt more realistic before the reverb (reverb? idk i was drunk while watching :3 )
I love how you started out like "haha engine goes vroom" and you've become a PhD-level fluid and audio simulation specialist and could easily be published in a scientific journal yourself.
This person is a god tier teacher. I had a professor in college who would constantly say: “In this universe” and proceed to explain the reasons certain engineering concepts are designed in such a way given the physical constraints of our universe.
This video gives similar vibes… like watching this you gain not just an understanding of piston heat engines but of the constraints of the universe in which we currently exist.
Seeing BeamNG being listed as a patreon member feels surreal
it's even weirder to be listed right next to them
As a car nerd hearing a engine simulation with a single cylinder sound that good is damned impressive. If that was in a game in the early 2000's I'd believe it.
Something that often gets overlooked is that a good portion of the engine sound comes from the intake.
Luckily my new fluid simulation can model intake sounds as well. For obvious reasons the "engine" in my video doesn't have an intake, but it'll be added soon
@@AngeTheGreatCool! Cant Wait! How long do you think it will be before we get to hear an actual engine in the Dev Vlog?
Near the end the two-stroke sounds quite much like a chainsaw engine, which makes sense, since they also have extremely simple exhaust and almost nonexistent intake geometries. Nice work!
o hi fippe
o hej
it's freaking awesome to see this all start to come together!
You have single-handedly piqued my interest in CFD over the past several months, you do incredible work. Keep it up!
I can’t wait to see this man’s work be used in proper racing games giving us a real connection to the motor.
my jaw dropped when i saw the pulses in the exhaust flow! every video's you published are top tier and amazingly detailed along with the work that just amaze me every time! thank you for everything Ange!!
Him saying BeamNG as in his first Supporter is such a good sign for future updates for us!
can't wait to see how this will be like in a few years
That sounds very close to a CRF 125 being run in a garage with minimal muffler. That's impressive.
Just keeps getting better and better, good work Ange!
your progress is incredible, keep it up Ange!
These videos are awesome, makes me wanna watch it fully
Thanks for all your work.
Amazing! I'm blown away more and more every video.
Amazing seeing the project develop. Sounds really good
Absolutely fascinating!
This looks so cool keep up the work!
The one thing I learned when doing the audio for the coin-op SF Rush at Atari was that only recording the exhaust noise did not make a very good engine sound. There is a lot of mechanical noises in the lifters, belts, etc, that needed to be mixed in to make it more convincing.
Thank you patreon supporters for doing what I'd like to do: throw money at this mad genius!
This is super neat! Love the audio signal processing and dynamical systems modeling. Very cool!
Incredible work mate, amazing seeing this coming along, and loving every moment of it, keep up the good work, and I hope you enjoy making this as much as we will enjoy using it :3
I love these as always!
I love how there's this massive task but you've broken it down into smaller pieces. It's really neat to watch how each task upon completion fits so well with each other :D
You have a really well organized workflow and development plan. We all see the progress :)
I've seen some of these engine videos YEARS ago and I just happened to randomly find this channel today. I find it amazing that you're able to summarise all the physics research you're doing in such an approachable and entertaining format. Thank you!
The amount of work and study you put in to this project is inspirational.
Looking promising, keep it up!
I am very impressed by your work. Seeing the progress is inspirational. Keep it up!
Just love what you have created with this simulator, so adaptable, well done!
Thanks for sharing! 👍💪✌
Very exited to see where this goes and that small engine simulation sounded like a small engine, very cool!
To me, it sounded like an engine constructed of PVC tubing. That suggests that in order to change the timbre to a more traditional engine, you'd have to model metallic materials somehow (and maybe you're already doing that - it's all a black box to me). Really nice work.
Best video so far! And I wasn't a siren fav until you revved one!
Amazing! Absolutely amazing! The added bonus(siren) was 100/100! Keep up the great work!
Another great video. Keep em coming!
This is such a satisfying combination of simulation and audio processing, two of my favorite fields!
I hope the final project has support for custom topologies and maybe even a VST version -- I'm very interested in this as a way to make unusual-sounding physically modeled instruments. It's so cool, and I'd love to use it in music.
Great update! It’s definitely starting to sound like an engine!
Also, I was amused that you get a lot of emails from siren enthusiasts.
I love the smaller videos, it's great to see the progress!
When one man decides to make more realistic engine sounds then the entire existence of the gaming industry.
Hell yeah, let's go bro. I love your vids. Makes me excited to watch.
THAT'S A VALUABLE RECOURSE!
This is the only guy that got me to not skip the sponsored segment lol
This man is going to make history and i mean it.
This is insane work yo
"A tube game for vroom vroom sounds"
As funny as that is, you're so wrong about that.
I can say that for the community, it's one of the best breakthrough there is for games, or for other applications !
Your work is amazing, always really interesting and visually stunning! Really impressive how you can do all the research and coding while making those videos this regularly, truly something else.
Keep up the great work (without overworking ofc). Looking forward to see all this implemented in an game like beamNG
Really looking forward to hearing the new engine intake simulation
That siren is amazing. I hope to see more progress on the engine sim
Great, as always
Back at it again with another banger
Constanly looking at the updates of this project, cant wait to see the final relese
I always get jealous of this work because it always blows me away.
Every time i see a video from this guy its like christmas and my birthday both at the same time :D
Ange top 3 youtubers, i love watching your stuff and using them
Ayyy can't wait for the next version of engine sim, exciting stuff
Keep up these video, pls, i love your content
honestly i had a feeling that sirens would be possible. i am no siren enthusiast. i just know that some of them work through air pressure-trickery and so it makes sense. that's so cool. im so excited.
Epic as always
This is badass, I wish I was able to make such consistent progress on my projects!
"A tube game for vroom vroom sounds" proceeds to make the most realistic simulation of engine audios ever
Can't believe all of this is happening! You're doing god's work Ange!
You are yet again continuing to blaze a path that I hope will revolutionize the engine side of vehicle simulators.
Good shit man
I'm a huge fan of what you're doing here and just recently discovered your Channel. I wanted to throw in my $0.02 on things that might improve the realism of your simulation and that's valvetrian noise. There's a ton of videos out there where builders will test cylinder heads without a block by just actuating the valves alone in normal sequence of engine operation to check for hot spots, friction wear and different manufacturer specs I don't fully know about. This is all to say , ive learned that a massive amount of the sound we hear produced thru the intake and exhaust of an engine is from the valves themselves. Something to consider 🙃
Always a good day when these videos drop.
Thanks ! ❤
i haven't played this in a minute that game looks so good and unique.
13:24 I was not expecting that to sound so good
This genius makes me wanna start studying software development and work in IT
You released this on my birthday. Thank you. I take it as a gift, despite you not even knowing of my existence on this planet. Your work remains, to me, a gift. Keep on keeping on.
Happy birthday!
God damn you're doing a phenomenal job.
That is a revolutionnary project well done. I assume that for racing games like assetto corsa or rfactor2 we will able to use this tool to build our engine sounds. Awesime keep it up!
Ange you dropped something 👑
This is combining 3 of my favorite things into one. Science, engines, and coding. Best part is its so accurate sounding too!
The siren sound was so realistic and cool
I cant wait for the release of this
I get the same feeling of joy and excitement from a new AngeTheGreat upload as I did when a new episode of Dr. Stone released, this stuff hits the spot
