Researchers Finagle Sound From Silent VideoResearchers from MIT, Microsoft and Adobe have developed an algorithm to extract audio information from video footage. They recovered intelligible speech from a video of a potato chip bag that was shot at a distance of 15 feet behind soundproof glass. The team also obtained useful audio signals from videos of aluminum foil, the surface of a glass of water, and the leaves of a potted plant.
