Oscilloscope Music - (Drawing with Sound) - Smarter Every Day 224

what's up I'm Destin this is an oscilloscope you've seen oscilloscopes before and you may have been intimidated by them there's a lot of knobs and like clicky things and it looks like something you could really mess up really easily but they're actually pretty simple devices the only thing an oscilloscope does is display a voltage over time and you can change those time bases to see whatever you need to see so you can do some analysis right I've got two different microphones set up I've got the left channel here running to the vertical axis I've got the right channel here running to the horizontal axis now if you combine these two in a really interesting way something pretty cool happens watch this whistle vertical axis watch this whistle horizontal axis if we combine them we can literally draw things I'm about to show you something incredible there's a whole subculture of people that have dedicated all of their free time to drawing things on oscilloscopes with sound I'm going to cut these lights outs and I'm going to come over to that camera right there I've got three cameras set up and I'm gonna push in to this oscilloscope and I'm going to show you one of these tracks it's called blocks it was specifically written to be displayed and heard with the use of an oscilloscope okay let me push in here cut the lights off here alright here we go you are looking at the sound you're hearing all of these waveforms were created using math to be both audibly and visually interesting at the same time [Music] welcome to Austria [Music] [Music] [Music] yeah okay so welcome to Austria this is Hansie hey and this is Joe veeneman these guys make oscilloscope music and today we're gonna see if we can learn how it works and there's a lot of smoke in here sometimes scared that my neighbors will call the firemen out you do it all the time that's awesome okay let's learn Jer beam is the artist Hansie is the genius to see the genius yes he's the genius so what do you do you're the programmer yeah I program and then also try to invent new techniques but really ours separation is not so strict so terrible systolic programmer and I know a tiny bit about music also so there's like a there's like a Venn diagram here and you're more the art and yeah and open up really and so you're are you trying to do this whole thing yourself like this is a whole genre now did you start it I know there were some people who did sort of similar things before but to this extent like with you know with the entire album I think that was not done before okay so you you've created an album that people can download yeah so I'm gonna need to break it down an oscilloscope has two signals is that how it works yeah so why it works like the etch-a-sketch sort of where you have two knobs and you can move the dot up and down and left and right there's these two inputs and one input moves it up and down and then removes it left and right but it's always a dot like even when you see a line it's really just a doctor going very fast so it's because it kind of burns its image onto your retina but persistence of vision is that why on your retina also the screen itself like the dissipation of the of the energy is not so fast so there's some so on the right we have Asti studio which stands for oscilloscope studio and their software that you created right yeah exactly we develop it as we go along and it's specifically for the purpose of making shapes for the oscilloscope but to be clear you sell this oh yeah music yeah okay all right what does it do it connects to blender there's a bridge and so blender is this 3d modeling application which you can use to make your shapes and what I can do here is I can add stuff for instance a cube and then it sends it right over into our studio and it converts it into a sound along the way a sound that again makes this really model that you were drawing in the first place so you've built a bridge between blender which is like one of the most popular 3d modeling animation yeah in these software packages yeah and so your software is a bridge to an oscilloscope so that people can visualize 3d objects with sound yes exactly that's things like how did you do that with like with math right yeah Mattson programming its algorithms mostly really yeah so you're really good at math I'm all right to be honest I'm all right yeah is always a way up get it so so what can you do so let's get this in here so that's a cylinder yeah so here it's very slow and you can see sort of how it figures out the paths what it's doing uh-huh and if I make it faster we start to again see the whole shape so you you take this object and you you divide it up into pieces so that we can draw segments or lines is the idea is more to find the past which you could follow with your pen without ever lifting the pen okay that's the main idea and so this maps is from the 70s roughly it's called the postman problem dart routing problem also really yeah okay so the the postman problem is how do you get to the most amount of points in the shortest distance right it's how do you how do you visit each street in a city map basically okay how do you go each Street at least once what's the least amount of doubles how do I change the art to rotate rotate and give it a second and then let it update man that's crazy dude so it's even nicer if you just animate it directly over here because you can get much more fluid motion and you can actually hear how the few points changes to sound dude you're insane man yeah it's just the start of it so now how do you make music teach me maestro what do you do so I'm just gonna use one of the example objects in there I'm gonna use a t-rex and I rotate that in blender right yeah was done in blender and it's just the object sent to OC studio and now of course I can do the same things here with rotations and changing the perspective a little bit and now I can just animate parameters wait a sec wait a second can we just stop and appreciate that I never knew that t-rex sounded like no you know okay I'm sorry didn't mean to interrupt so you've already seen the trace plug-in and now I can also just add an envelope to this and then it switches to the Timeline view and now here I can just draw timelines and repeat them and so you see now this just happens and it animates it and this is basically how I make music I use lots of different parameters that are here then all these plugins and I animate them to create music out of them so you use keyframes it's pretty much like keyframes just like in video editing software that's what you do and now for example if I also animate the grid then I can do like sort of generative melodies [Music] it's almost a song already can you take the string source Rex and have him slowly rotating as it's beating like that of course really maybe in this direction so you can pick an accent yep I can also do this and also one cool thing about the software is that these sliders don't really have any limitations you can also just type in any number and make it go like really fast so that nothing makes sense anymore but it creates some interesting we know a tornado Tyrannosaurus Rex yes one attorney a Tyrannosaurus Rex sounds like it's a tornado soros rakes chordate asaurus rex i know you appreciate it because you built it but like the world needs to know that you can do this yeah it shouldn't matter yeah so I can also use different objects here and you see it does just the same like whether it crashes this is actually something that you can do very nicely nah see studio you can divide by zero and then it crashes really yes very high right yeah I like to not put limits in the software like I think if you want to input the stupid number you should be able to import astutely number really yeah I see like we're all grown-ups rightly divide the use of math sure be him really wanted me to understand that you didn't have to have fancy equipment to make its own scope music you just had to know the math he pulled up Ableton Live a digital music sequencer and he quickly visually programmed something using trigonometric functions then he simply started twisting knobs and proceeded to blow my mind so basically the circle is strong with the point that go that goes around the circle all the time now the thing that you learn in school is the sine and cosine is about triangles most so these triangles would look like this so the sign of the circle that is the length of this line here and the cosine is length of this line if you want to see what these frequencies are playing then you get this image here but you can hugely proud dude did you just do that with you're doing a Fourier transform on an oscilloscope using Fourier transforms but it's basically just the finder to a fine because I know what it is saying you just then you can see that this is the same signal sign they are just shifted a little bit so that that's what the difference the Sun actually is it's just shifted 90 degrees you just did that with knobs basically just showing trigonometry stuff that you should have learned in school it's mostly an interesting combination to use this very old device which is almost forgotten and people throw it out of the labs and but then to apply new techniques to it most of the mats we use is old old like 17th century sort of maths and it's really still there's there's something about it to just work with it and to not just do it as a maths exercise but to play with it and look at it and feel it and I think this the device really encourages you to play with this type of mathematics so the beauty of oscilloscope music is that we're at the point in time in history when digital technology is taking over the world but we still have access to analog technology so we can yeah we can sort of rediscover it like stuff that they could have done on the oscilloscope if they headed digital technology so it's sort of what if it is state I have met a lot of smart people making smarter every day like genius level people but the interesting thing about cherubim and Hansie is that they have genius-level intellect in multiple areas math art music like electronics programming these guys are incredible so I wanted to see how far I could push them over the years I've made some really interesting videos with a high speed camera on smarter every day so I just wanted to see what they could do with pure math so I took some of the best hits right so like the chicken with the stabilised head of vortex collision the bullet hitting the Prince Rupert's drop the solar eclipse laminar flow I asked them what they could do with just a couple of days in pure math and what they sitting back was absolutely incredible this is mind-blowing [Music] [Music] [Music] this video was sponsored by Casper this is an incredible amount of work I want to explain this to you this was done with a lot of different types of software we've got SolidWorks Adobe Illustrator this is an SVG file that the Casper team sent me we've got Photoshop in there we're using blender aussie studio I'm using Adobe Premiere right now this is sound Casper what is Casper Casper sells mattresses and it's going to change the way you sleep they send a box to your house and you get to open it next to your bed that's supposed to be a bed there's a lot of vertices on it so it's really hard for the oscilloscope to model it but just trust me that's a bed and the way it works is you get the box it comes to your house and you get to open the box and once you open it it's amazing there's five different Casper mattresses to choose from there's the original Casper we sleep on the wave the essential the hybrid wave and the hybrid Casper you want to see the wave inflate on the oscilloscope don't you it's happening right now that's that sound that's the mattress use your imagination there's a lot of math involved so just pretend that's a mattress and that you're really excited to sleep on it the way the Katzman works is it rolls out it inflates automatically and you get the best night's sleep you've ever got that's how this works you can get one by going to Casper comm slash smarter and using the promo code smarter to get $100 so if it's really hard to keep all this straight in my mind I've got this in my ear I can hear the audio you can hear anyway you get to sleep on this thing for a hundred nights and if you don't like it they'll take it back no questions asked the reason you can buy such an awesomely engineered mattress for such an affordable price is if they cut out the middleman and you can buy directly from the people that invented it seriously this is one of those things where I thought I knew what a comfortable mattress was like but I didn't until I try to Casper you will like it again this is sound and this is really hard to do Casper comm slash smarter use the promo code smarter to get $100 off select Casper mattresses terms and conditions apply that was incredibly difficult to do that took a week I hope you enjoyed it I also hope you enjoy a Casper mattress i legit asleep on one and have four years and I like it my wife likes it too there's a bunch of other ads that I've done Kaspar mattresses you can see her opinion on that but we seriously light cast four mattresses and we know you will too all right that's it let's go talk to Hansie inter p.m. and thank them for their time and all of the stuff they taught us how to do it's incredible they are legit wizards please go support their work it's oscilloscope music calm yes and you have a YouTube channel right yes what's the name of the YouTube channel it's just in feminism okay and then you have Aussie studio on oscilloscope music calm and can people get these files like how does that work we we don't just want to release new tracks but we actually want to release an EP where people can do the same thing so it will include all the Aussie studio files so that people can open them and change every parameter they want oscilloscope music calm get RC Studio get the new EP play around with the files that's cool man thanks for doing this guys this is awesome and thanks for being a thanks for coming yeah thanks for the hospitality this is amazing so anyway I'm Destin I am getting smarter every day these guys are awesome Jerr beam Hansie thank you anyway have a good one bye what is that thing to the nose it's people going into a nose [Music]

Mind blowing, never expected a Tornadosaurus Rex to sound like that.

Guys, check out r/OscilloscopeMusic if you want to see more of these.

White Oscilloscopes are ideal for displaying these, you can also convert an old CRT monitor to have its coils direct the electron beam in correspondence with audio channel.

"Welcome to Austria" Killed me. I legitimately applauded that transition.

[u/BigRedTek]

Every time I see a video with a scope, I always hope it's one of mine ... this one is from literally before I was born ... but I'll still take it!! Yay scopes, and awesome video as always!

Always impressive to me that they're still running well after 50 years. I need to try these patterns on the newer digital ones, we don't get the phosphor fade anymore, but you can get a similar effect with software. It never has quite the same glow as these old ones do.

I think this is the coolest thing I've ever seen.

[u/ThisWizardDidMath]

This was a really cool video. I don’t know why, but the cos and sin coming out of the circle really blew my mind.

[u/yodafunk]

This TOTALLY reminded me of an arcade game I played growing up. QIX https://www.youtube.com/watch?v=EdEOH5O2kCo

Favorite part of this video is you can divide by zero because we are adults.

[u/vicorator]

In my first yeart of the physics undergraduate was filled of dread of having to work with Oscilloscopes. But this type of content intrigues me to possibly to dive back into it.
