Carnegie Mellon University researchers develop camera that sees & reconstructs sound

Researchers at Carnegie Mellon University in Pittsburgh, PA have developed a camera system that can 'see sound vibrations with such precision and detail that it can reconstruct the music of a single instrument in a band or orchestra.' The novel system, developed in the School of Computer Science's Robotics Institute (RI), uses a pair of cameras and a laser to 'sense high-speed, low-amplitude surface vibrations.' The vibrations are then used to reconstruct sound and capture isolated audio without...
