Researchers built a low-cost camera system that recreates sound from vibrations

@ 2022/06/23
Researchers at Carnegie Mellon University have developed a camera system that can seemingly detect sound vibrations with a level of precision that makes it possible to recreate the audio without inference or a microphone. A team from CMU's School of Computer Science's Robotics Institute (RI) built the system, which has two cameras and a laser. It can detect "high-speed, low-amplitude surface vibrations" that the human eye can't see, the university said in a press release.
