Great talk about about how the incredibly tiny movement caused by sound-waves on matter, captured via a high speed camera can be used to recreate the original sound. It also covers the potential of the technology.
Packed full of useful and easy to understand information. If you've got a spare 20 minutes, I recommend it.

MIT PhD student, computer vision wizard and rap artist Abe Davis has co-created the world’s most improbable audio instrument. In 2014, Davis and his collaborators debuted the “visual microphone,” an algorithm that samples the sympathetic vibrations of ordinary objects (such as a potato chip bag) from ordinary high-speed video footage and transduces them into intelligible audio tracks.
““Imagine someone listening in to your private conversation by filming the bag of chips sitting on the other side of the room. Oddly specific, I know, but researchers at MIT did just that: They've created an algorithm that can reconstruct sound (and even intelligible speech) with the tiny vibrations it causes on video.” ” — The Washington Post, August 4, 2014
