Researchers 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. Objects vibrate when hit by sound, creating a subtle visual signal that is usually invisible to the naked eye. The researchers sought to reconstruct the sounds causing such vibrations.Researchers Finagle Sound From Silent Video
