eli5, how is audio and video actually recorded?

177 views

It is really hard to imagine how I am able to rewatch a moment of the past just because some fancy camera recorded it? If I think about it it feels very unnatural.
What are the key parts of microphones and cameras that make them work the way they work?

To put it more childishly, a camera is just a robot eye and a microphone is just a robot ear. They work according to roughly similar principles as their biological counterparts, except they’re also designed to save the input for review. If it’s the *recording* itself that’s blowing your mind, then you want to look into information theory.
