From the Ted Talk by Abe Davis: New video technology that reveals an object's hidden properties
Unscramble the Blue Letters
So a couple yares ago, I started working with the folks that created that software, and we decided to pursue a crazy idea. We thought, it's cool that we can use software to visualize tiny motions like this, and you can almost think of it as a way to extend our snese of tcouh. But what if we could do the same thing with our ability to hear? What if we could use video to curapte the vibrations of sound, which are just another kind of motion, and turn everything that we see into a microphone?
Now, this is a bit of a sgtrnae idea, so let me try to put it in perspective for you. Traditional microphones work by converting the motion of an internal diaphragm into an eericlctal signal, and that diaphragm is designed to move reiadly with sound so that its motion can be recorded and interpreted as audio. But sound causes all objects to vibrate. Those vtinarobis are just usually too sutble and too fast for us to see.

So a couple years ago, I started working with the folks that created that software, and we decided to pursue a crazy idea. We thought, it's cool that we can use software to visualize tiny motions like this, and you can almost think of it as a way to extend our sense of touch. But what if we could do the same thing with our ability to hear? What if we could use video to capture the vibrations of sound, which are just another kind of motion, and turn everything that we see into a microphone?
Now, this is a bit of a strange idea, so let me try to put it in perspective for you. Traditional microphones work by converting the motion of an internal diaphragm into an electrical signal, and that diaphragm is designed to move readily with sound so that its motion can be recorded and interpreted as audio. But sound causes all objects to vibrate. Those vibrations are just usually too subtle and too fast for us to see.
