Whoa. Notch posted this on his Twitter and when I saw it I thought to myself, "self", I said, "how cool would it be to make that in Löve?"

And here it is.

So I tweeted it to Notch. (Not promising a reply. They never reply to my Tweets. Everyone else's, yes, but mine, no.)

I am once again impressed for the second time tonight. Dayum...

that's really cool! I was wondering why the other songs looks like noise, it's an encoding problem?

That song was specifically written to make visuals when run through an XY oscilloscope. Other songs do display properly.

In order to understand how it works you need to know how sound works. The song made for this show is specifically made to place certain sounds in the right place to make the line make shapes while still sounding like a song and not just random sounds.

cool, it stops playing for me after a while though. the song keeps playing but the visualization doesn't

That is interesting. Does anyone have some URL so I could read more about the algorithm? It would be fun to generate (or "encode") graphics, not only to render it (think: paintbrush to music conversion

)

Well, the 'algorithm' to calculate a sound for an image isn't that hard, it's making it music that's hard. Since it's a monochrome image, the only data you need is the X and Y position, which are indicated by the 2 channels (it's stereo music).

But aren't the samples played one at a time? Or do you take a bunch of samples at a time? Is that decided by the refresh rate or something?
