TFA is not putting music on an oscilloscope. Some of it is actually plotting frequency vs time in the video, so it's nice demo stuff but not true oscilloscope music.

Long ago I did like you and converted an CRT TV to accept audio on the deflection coils (left, right -> X,Y). I can highly recommend 2 particular songs for that setup:

1) Cathedral by VanHalen

2) Lunatic Fringe by Red Rider

By all means use a CD if you can rather than MP3 - I'm not sure how degraded the MP3 would be so maybe it's fine.

From TFA:

> Oscilloscope Music is music that creates it's own visuals.

> The same signal that goes to the speakers is also fed into an analog oscilloscope to draw green glowing lines.

> The left and right audio channels correspond to the horizontal and vertical axes of the image.

> Parametric functions are meticulously crafted to create synesthetic geometries in a lab aesthetic that is retro and futuristic at the same time.

> The tricky part is to create images that sound good and vice versa, which demands novel methods of synthesis, mixing and mastering.

This is exactly was TFA does.

you must have a very unique definition of music. by every definition I've looked up, this meets all of them.

because surely you're not disputing the oscilloscope part of it

Yes, I'm disputing the oscilloscope part of it. An oscilloscope does not plot pitch vs time. You could devise circuitry to do something like that.

Having plugged audio directly into an oscilloscope, I can say that's not how it works. Well, not all of it. The into seemed more like it might actually be left/right audio into a scope, but the other parts did not.

You're right, it doesn't, and that's not what's happening here. It uses the X/Y deflection mode of the oscilloscope, plotting left channel vs right channel.

If you don't believe it, play it on an oscilloscope yourself. (I have!)

i'd suggest you do it again before making baseless accusations. they provide you the ability to download the audio. they even provide a bit of software to drive lasers with the data.

as a follow up to my own post. I couldn't remember the video, but the YT algo found it for me[0]. Smarter Every Day did a video with the same people from TFA that shows exactly how they do these. I can't find any better evidence to show your "thoughts" being totally baseless.

I hate double replying, but I was busy

I think it is plotting music on an oscilloscope. It just happens to have some very meta visuals.
