TLDR: bro makes specially shaped sound that wen put into an oscilloscope (name of the little screens) creates images.
Long version:
Oscilloscope is a device used in labs for visualising a signal. It has a screen and two inputs. On the screen there is one dot that can move and the screen remains light for some time, so a signal that is repeating can look like a stationary shape, not just a moving dot.
It of course has the ability to see the signal in relation to time, but for us, the important is mode that sets the first input as control of the X position of the dot and second input as the Y position control.
Then he creates the image through a computer program that just has the shape inputted in vector images (that is a way to store lines/functions as images in a computer) (you can just make that image in Inkscape), or in this case, an animation. Then the program just figures out how to move the point along the lines, that means using complex math, like Fourier analysis, to figure out a pattern of what voltage the input must be set on both axies separately and then the computer or some outer device makes those voltages, which go into the inputs and make the shapes.
As for how he makes it do the sounds, anyone's guess. If we assume that the same signal that makes the images is in the speakers, I think he just distorted the signals so the speakers sound roughly like music to human ears.
Thanks for coming to my ted talk
About how they make it do the sounds, i believe they're just playing with the "drawing speed", basically, for lower notes, they make the relevant signal have a lower frequency, drawing the shape slower, and the inverse for higher tones. At the very beginning you can basically see this. Also i believe the drawings themselves also play with the frequencies, specifically with pairs of them. What i mean by this is that, when both signals in an oscilloscope have the same frequency, the drawing is the snowflake, but to draw the other, more complex shapes, i believe they basically play it like a crt scan, with one signal doing a lot of drawing for every wavelength of the other
I imagine the distorted lines such as the ones i. the larger snowflake are also some compromise for getting the right note by changing the length of the path the dot follows.
Kinda. The screen is made of stuff that after hit with electrons glows for a while, so yeah, you could kinda say it's like using a laser with a camera.
Idk I'm just speaking from what we've been told and shown in school. It works on any oscilloscope cuz the movement is very fast. I'm not some expert, I can't tell you much more
To explain how this works will take a lot.

Man for all the o-scopes I work with I never thought to do anything like this lmfao. Idk if I'd have the patience to even come close to that.
There are programs to do the pictures for you, it's actually not that hard to do, though don't know how to pull off the sounds with it
Interesting, I have never attempted something like that so I might actually take a look and see if I can pull it off
Wait till I show you how we played Space Invaders on spectrum analysers in the late 80s
Early out of tech college I made a homemade curve tracer to check PN junctions with the Lissajous patterns
are you making up words again Randy?

so, not unlike a laser show on a wall, but instead the "wall" is the O-scope display? or am I missing something?
Kinda. The screen is made of stuff that after hit with electrons glows for a while, so yeah, you could kinda say it's like using a laser with a camera.
you mean phosphors? I was a broadcast engineer in a previous life. I've used a few O-scopes but never seen THIS done.

dangit. So I need an instagram account now?
Hey, its that funny Australian man

As a wannabe audio enginerd, this scratches an itch I didn't know existed.
WHAT

Is that Deadmau5
If you like this kinda stuff check out Jerobeam Fenderson
Does Jerobeam Fenderson sound like a real name?
Grow up Hailey, it’s me.
Listening now, can’t tell if I like it but I can’t turn it off for some reason.
Blocks was awesome
That was genuinely cool.
Please release this as a song
O-scopes are not easy. I am impressed!
As a musician, I have no clue what this is…but this rips.
I was waiting for the beat to drop…
And then the clip ended.

Damn
Stranger Things vibes.

Man this makes me wanna get my NES out of storage and hook it up.
Was that Metroid?
Is that "Children" by Robert Miles?
Isn't Oscilloscope tones the origination of instrumental tools like synths?
I want this to play as I lay bleeding out in the snow.
