| Algorithm recovers speech from vibrations of potato-chip bag filmed through soundproof glass |
| 2014-08-05 |
| Ready your tinfoil helmets, here it comes. Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass. |

| #3 We played with 'passive' laser audio recording in school during the early 70's. Doing about the same thing as here, without the fancy algorithms. (A lot more wires and 'boxes' though, I'm sure). The concept is nothing new. Pulling the info from a video is pretty cool, though. |

| #2 In the 70s the sheriff at Ogallala had more arrests of top 10 wanted and others than anybody else in the USA. The Mafia even had a hit order on his drug dogs. How did he do it? His son was a EE and designed him a laser he could bounce off windows of perps cars (on I-80) after he would flip his flashers on. It would pick up everything they said in the car - stuff like hide the drugs in the ashtray in the glovebox. He was one of those officers that always had a pot seed to slip under his thumbnail and then spot on the carpet so probable cause was never a problem for him. It was quite effective. |
