+ - New way for Spys to listen in on us->

Submitted by gurps_npc
gurps_npc (621217) writes "Sound is just vibrating air. When it hits glass, it vibrates the glass and it is well established that a laser aimed at the glass can detect those vibrations and computers can turn it back into sound. Now, we don't need the glass or the laser. Researchers at MIT, Microsoft and Adobe have shown that by analyzing a video that contains something vibrating — say a bag of chips — a computer program can work figure out what noise caused those vibrations, even to the point of reconstructing speech."
