content: Techmoan and AvE and a few others have been doing videos about Jerobeam Fenderson's oscilloscope music, which is some mind blowing fun. Synthesis was never as cool as this. Hard to pick a favorite.Full playlist (worth watching them all):https://www.youtube.com/playlist?list=PLFgoUhNvMLrr8izq38HX6rjFR-nkfklxw

content: Quote from: strangersound on November 24, 2016, 07:33:44 amBetter than watching the video, if you have an appropriate oscilloscope you can feed the left and right channels from your sound card in to the scope. The sound on the youtube videos produces those images directly. It's kind-of freaky to know that those images are in the sound that you are hearing.

content: Quote from: mc172 on November 24, 2016, 12:46:16 pmThe images show that signal amplitude remains relatively large even when the voice fades. My guess would be that a low-frequency (<100Hz) has been added to the signal. It should be possible to capture the audio signal and explore its content on your computer with something like Audacity.

content: Quick and dirty comparison. Download the scope from here:https://www.zeitnitz.eu/scope_en- Installed and worked without a hitch. License only required for commercial use. In the settings tab you can find the audio routing options if it doesn't just work out of the box for you. Nice little piece of software. I messed around with some other stuff that kept spitting back errors and found this. It's got a signal generator (w formula input), frequency analyzer, audio recorder, etc. You can break various things into separate windows. I was fairly pleased to be using the signal gen and the scope/xy seconds after it opened. Worth a download, I think.Click play on one of the videos and get a good look at what YouTube is doing to your audio.

content: Quote from: strangersound on November 24, 2016, 05:42:12 pmIf you mean that the XY graphics don't look as good on your software scope as they do in the Youtube videos, I would be inclined to blame it on the software scope rather than on Youtube.Even many "real" digital scopes (with dedicated hardware) struggle to produce a good, smooth XY display. I still get my old 20 MHz analog scope out for XY visualization.

content: Quote from: ebastler on September 22, 2019, 05:21:20 pmDefinitely. Using the XY mode of scopes to emulate a "vector" display often gives crappy results with most modern scopes in general.

content: Looks like that device is AC coupled, which is creating a lot of distortion on the display. Makes sense if it is just an audio analyser, it doesn't need to see DC.

content: I'm skeptical.Are those waveforms really what's generating the displays (on an X-Y driven oscilloscope)?Or is it just some CGI made to look like an oscilloscope?I ask because while some of the "music" sounds identical it generates quite different patterns.I have no trouble believing that one can do amazing things with an X-Y driven 'scope.Just not sure that's actually what's being done here.

content: I bought the album from the Techmoan video, and I can confirm it's real. The main problem I've run into is that most computer sound outputs don't have good enough low frequency response. You don't need to go all the way to DC, but 20Hz is much too high of a cutoff frequency.Ironically, my best results are with an old very cheap USB audio device that is flat down to about 1Hz. It had 100uF coupling caps (which were installed backwards...). I replaced them with 330uF caps while correcting their polarity, and added a simple R-C filter since there was absolutely no filtering on the output.I tried installing larger coupling caps in a nice Creative USB sound device (went from 10uF to 330uF), and that took care of the low frequency problem. Unfortunately, it has an inverting amplifier on the output, so everything is upside down and backwards. Inverting the files in Audacity takes care of that.The most impressive thing about that album (N-Spheres) is the little 150 KB program that can synthesize the while album, and simulate the scope display on your monitor. I just wish it had an option to invert the outputs since several of my audio devices are inverted.

The oscilloscope scene might not look like much for someone who didn't know the movie, but the scene was a lot in the context of that sophisticated party (the oscilloscope was in fact a fancy intercom in a fancy mansion).
