Let’s talk a bit more about digital sound. Thanks to a mathematical theorem, we know that a bandlimited signal can perfectly be represented by a series of discrete samples that occur at twice the rate of the frequency of the bandlimit. OK, that’s hard to explain in a little descroption blurb, so the video is probably your best bet.

This here is the video of Monty’s. YOU SHOULD TOTALLY WATCH IT!! There is so much good stuff in here and it’s a great resource for dispelling some of the myths of Digital Sound.

This is his original article that inspired the video (I think--it’s a great article anyway):
