Can You Recover Sound From Images?

The video explores the possibility of extracting sound from images by capturing tiny vibrations with a camera. It discusses the challenges of this process, such as the need for high frame rates and the difficulty of distinguishing between actual motion and image noise. The experiment demonstrates that while full sound recovery is limited by current camera technology, some rhythm can be detected. Advanced equipment can potentially recover more complex sounds, including human speech.

What is the significance of sampling at least twice the frequency of sound?

What did the speaker mean by 'confirmation bias' in the context of the experiment?

What was the final conclusion regarding the ability to hear the recovered sound?

How did the speaker feel about the potential of the experiment at the end?
