Boffins at MIT, Microsoft and Adobe have developed an algorithm that can_bring audio to silent videos by reading vibrations that are not visible to the naked eye on objects. In one example, the team was able to recover “intelligible speech” from a video thanks to vibrations that a voice made on a packet of crisps, which was positioned 15 feet from the camera and behind soundproof glass. Other tests successfully reconstructed sound using vibrations from aluminum foil, a glass of water, and a potted plant. “Sometimes we watch these movies, like James Bond, and we think, ‘This is Hollywood theatrics....
