Is this process of sampling similar to how a digital camera works?


Is anything special done to the audio samples to reconstruct the sound? Or is the assumption just that 44,100 times per second will be sufficient


I'm also interested in the 44.1k sample rate. Our hearing can only go up to around 20kHz, why is our sampling rate twice that value?


How does Nyquist's Theorem inform the number of samples taken for a pixel? What is the maximum "sample rate" of the human eye for a pixel?


Would there still be any (minor) improvements if we sample above 44,100, or is this all we need because we cannot tell any differences by hearing them?
