An hour ago and on the front page with no comments. Probably because we are all still playing with it.

This :P

Way to spoil the lighthearted mood of a fun oscilloscope simulation... I've noticed, and dislike how unwelcome it is to make a simple acknowledgement or agreement on HN. Must be something about the voting system.

Right? How good is this?!

tomxor4• 8 years ago

For those of you a bit lost with the initial setup, click the "sweep" and "microphone" checkboxes to get something more familiar.

And try whistling, snapping your fingers, and growling and humming, not just speech.

Most people can whistle a nearly perfect sine wave, and shortly thereafter you'll see what frequency and volume really mean.

Or turn on the Signal Generator and play with the multipliers.

Love the visuals, is the source code open? A nitpick, I should be able to click on "microphone" instead of having to aim at the small checkbox, this is easy if you wrap it in an HTML label tag.

is the source code open?

It is, look at the page source.

The repo was only the source for the line drawing code.

pantalaimon• 8 years ago

I tried playing some of Jerobeam Fenderson's music on it and it works great! :D

Completely locked up my FF + iMac.

johnpowell• 8 years ago

No problem here on FF 58.0.1 and OS X 10.13.2

AtomicOrbital• 8 years ago

runs fine on FF nightly 60.0a1 on ubuntu 17.10 which has nvidia 940mx gpu

kakarot• 8 years ago

I can't get it to display anything. The console is ablaze with CORS errors. Firefox 58, Fedora 27.

Reminds me of the Scan Processor Studies by Woody Vasulka & Brian O'Reilly. https://vimeo.com/7517418

Really eerie stuff.

Very nice and realistic effect. As a low-level electronics hobbyist I was pleasantly surprised to find "entry level" 50 MHz digital oscilloscopes in the $150-$200 range these days. I picked up a Siglent to help me through Horowitz & Hill's The Art of Electronics labs and it's been pretty fun. I also have used it just to see what's going on on a cheap digital level I bought with USB output and some other things. Definitely a neat tool. It does sit on the desk more than I'd like these days though.

This needs some samples

Here's the music and oscilloscope art demo, the artistic goal of the project ... https://m1el.github.io/woscope/

anilakar• 8 years ago

Acid test: run Youscope on it. Seems to work relatively well.

claforte• 8 years ago

Awesome, my whole family played with it for 15 minutes, a great way to introduce wave theory to 8-10 years-olds! Works great on Windows 10 + Chrome.

fdavison• 8 years ago

Seeing an oscilloscope displaying a Lissajous pattern when I was eight years old was one of the things that sparked my interest in electronics. In 1962, by cracky!

lennoff• 8 years ago

try it with https://github.com/m1el/woscope-music/blob/master/oscillofun...

jeffhuys• 8 years ago

Unavailable in Safari. Only stereo in Chrome.

It IS available in Safari, but not stereo as it says. Sierra.

DINKDINK• 8 years ago

awesome! would be nice if the engine interperlated between parameter changes instead of getting those abrupt digital steps.

To get audio from another program, you can either physically connect your audio output to your audio input, or use third party software, such as VB-CABLE on Windows or Soundflower with SoundflowerBed on MacOS.

Read my mind

Vinyl "music for oscilloscopes"....

I made this oscilloscope simulation + sound last year : https://www.shadertoy.com/view/ldSfWV

Beware : you need a good GPU

Exras• 8 years ago

Nice reflection on the monitors edges.

JKCalhoun2• 8 years ago

Wow, very cool. Kind of an inverse oscilloscope though — you adjust the input freq not the display freq.

aroman• 8 years ago

Try this one: https://www.youtube.com/watch?v=rtR63-ecUNo

I don't see any visualization, on Mac 10.3.2 and Chrome 66.

hazeii• 8 years ago

Click on 'Signal generator'?

rosstex2• 8 years ago

I hit "Reset All" and it started working :)

eigenvalue• 8 years ago

This is amazing! Turn on your microphone and try playing with the sliders!

The obvious musical selection to use in conjunction with this is “YYZ”

EDIT: Okay, I'm watching / listening to Dave Holland’s “Jugglers Parade” which is punchy and whose dynamic range builds slowly. It’s pretty freaking cool. I’m sure everyone here has musical favorites that they’re having fun with too.
