Show HN: WebGL-powered oscilloscope emulator

That was one of the highest-fidelity visual experiences I've had on the web. I know there's no more information being displayed than what's in the audio channel, but I feel like this sort of experience just wouldn't translate well to any current video encoding, even at enormous file sizes.

Thanks for building this and for sharing!

Nice, I assume this is XY-mode by stereo channel. I did a little writeup here: http://cookingwithsound.com/an-xy-mode-oscilloscope-in-your-...

If you want to get in touch, I'd love to add more detail about how the code works :)

That could be an awesome previewer for .ild files (Laser Show stuff). The OpenLase and VectorBoy projects might like to hear from you.

It would may also be really nice for rendering the old vector games in MAME - I have a Cinematronics emulator that can run about 13 vector games too, mostly black and white.

I like it, but I would prefer a plain oscilloscope function, and being able to connect it to a Web Audio source of mine.

It says I don't have webgl, but chrome://gpu says "WebGL: Hardware accelerated". Not the first time I've run into this.

khrậng. amazing.
