How ultra-fast cameras can ‘listen’ to music by recording a bag of crisps

Researchers at MIT, Microsoft, and Adobe have developed a piece of software capable of “reading” sound off tiny vibrations in inanimate objects.

That’s music from vibrations in plant leaves.

That’s human speech from a bag of crisps.

And, yeah, that’s the sound of my jaw on the ground right now.

Because of a little quirk in the design of most cameras’ sensors, the researchers managed to extract information about high-frequency vibrations even in footage photographed at 60 frames per second.

Watch how it happens:
