This needs some samples

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

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.

It's because it doesn't really contribute anything, and some people are stricter about that than others. The easiest way to turn that simple acknowledgement with downvotes into a neutral or upvoted comment is to just add a simple sentence with your own thoughts, or what it reminds you of, or anything that actually justifies the use of a comment instead of just the upvote button.

It's just one of the ways HN is slightly different than other forums, and while it sometimes comes across as negative, I think overall it encourages better comments.

The positive reinforcement of "cool webtoy, bro" contributes more than you'd think.

I can sort of understand the "this is not a chat room" attitude only leave constructive comments or whatever. But sometimes you want to just leave something more than a button click because there was more resonance than is expressed in a binary "yes", yet you don't necessarily have anything insightful to add.

Anyway... that is my opinion, but I expect it's unpopular and will not be surprised if more downvotes come hurtling my way.

I think the disconnect is believing it has to be insightful. There's a large area there where you can work within to make a comment more signal than noise. Just explaining why you agree is usually sufficient.

Some forums are perfectly fine without a distinction of contribution, such as reddit. Others, such as here, have a culture that tries to promote more substantive comments. Neither is better than the other, but both excel at specific things. If I want reddit style comments (and I do, often), I'll visit reddit. If I want HN style comments, I visit HN. Forcing redditors to be more serious or HN users to be less serious doesnt serve either community well, and would likely cause both to be similar and mediocre compared to what they were before.

The whole point is that this is a place where someone can dive deep on the differences in etiquette and culture between reddit and HN and not worry too much about being called out for being too serious or cramping other people's good time, because some people find a discussion like that a good time even if they also like 10+ comment chains of jokes and crowd sourced movie quotes at other times.

For that reason, I don't really expect you to get downvoted. You explained and justified your position, which I find is usually all most people here really expect as a minimum.

Right? How good is this?!

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.

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

Beware : you need a good GPU

Nice reflection on the monitors edges.

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.

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.

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.

source code: https://github.com/m1el/woscope/

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

Vinyl "music for oscilloscopes"....

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.

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!

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

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

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

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

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

Really eerie stuff.

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

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

>Unavailable in Safari. Only stereo in Chrome.

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

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

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

Click on 'Signal generator'?

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

Completely locked up my FF + iMac.

No problem here on FF 58.0.1 and OS X 10.13.2

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