Let’s say the manufacturer up the street is making widgets with a 3D printer and you’d like to get in on that action. If you want to clone those coveted 3D objects, all you need is an audio recorder in the room with the printer.

According to a new paper published in Science, researchers have even replicated a key using this technique.
