Eli5: How is it that our voices are distinct enough to be captured by a recording instrument and replayed accurately

Question

For example, say 100 people each read / sang an identical passage into a recorder. It seems as though the frequency, amplitude etc that is captured wouldn’t anywhere near specific/precise enough the be accurately represented when played back. I.e what variables are at play that allow us to easily discern the 100 distinct voices when replayed? Thanks!

Answer 1

Depends on quality of recording device and noise cancelation, distance from mic/recording device from sound source, and you have to understand when you speak you hear a deeper version of your voice because of the bass of your skull or something like that
