You'd need a phd and a high enough screen refresh rate to get accurate audio from a video of vibration, I think.
Consider CD audio is 44,100 'frames' per second, while HD video is between 24 and 60 frames per second, so there's just not enough information to work with to reproduce high frequency sounds.

Of course, the display is the limiting factor, irrespective of the camera speed.
I imagined if a high speed camera was used, the footage slowed, then corrected for frequency after. As you say, not easy.
