rtoz writes 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 (video) photographed from 15 feet away through soundproof glass.

Could this be used by NASA to look for intelligent life on other worlds by measuring objects in the same fashion?

Are they not doing this already in CSI? I'm sure I saw them enhance an office security video of a post-it note, reflected off a monitor screen, magnified a couple of times, and there they had it; complete dialog in stereo, with accompanying analysis of voice stress so they knew who was lying. Isn't science wonderful?
