How does autotune

My best guess is that it does a Fourier analysis to guess the fundamental of the incoming sound, finds the closest pitch in the scale you've set it to, and does rate adjustment of a ring buffer to try to make it match.
Answers with as much technical/mathematical detail as possible would be great, as would a "dummy with basic understanding of DSP" breakdown.
