Recovering sound by filming a plant

If you scroll down a bit there's a video.

Most IDM 2014.

Very cool! Could be useful in espionage I'd imagine.

Yeah, you could essentially build an ultra long range microphone with a telescope or something. Would love it if they'd test how far they can go.

Made me think of this scene for some reason:

Science is getting scary.

That's pretty amazing, but I lol'd hard at the rolling shutter results. Mary Had A Little Chopped & Screwed German Industrial Circa 1995.

Genius to use that data in that way.

Holy fuck. Somebody needs to use this algorithm to make an audio plugin

Or you could approximate the same sound by rerecording your music on a dictaphone in an overcrowded public restroom

Tried that before. I'm not allowed in overcrowded public restrooms anymore

Found this very interesting

Suppose, for instance, that an image has a clear boundary between two regions: Everything on one side of the boundary is blue; everything on the other is red. But at the boundary itself, the camera’s sensor receives both red and blue light, so it averages them out to produce purple. If, over successive frames of video, the blue region encroaches into the red region — even less than the width of a pixel — the purple will grow slightly bluer. That color shift contains information about the degree of encroachment.

So we have the technology for 100,000 fps and they were using 6,000 fps. Cool to think what can be done if they get the use of a 'super' camera.

Saw it in my facebook feed today, cool stuff.

Reminded me of CIA & NSA using laser's to pick up vibrations from long distances and translating it to audio, also being able to pick up vibrations from glass of water et cetera for decades now.

A d.i.y video example for lower budgets;

Yeah laser mics are super cool. Would be cool to try that on a drum kit or something.

Cool.
