Episode notes
The human ear cannot hear the difference for anything that represents frequencies above roughly 20 kilohertz, even like young kids who have perfect hearing. Anything that is higher than that sampling rate of 44.1 or more precise than the 16 bit samples that we're storing there, that's beyond the realm of human hearing. And in practice, you can perfectly represent that full curvature of those sound waves. Most DACs will approximately output the perfect sound wave, like it will be way more perfect than you think, even with way fewer samples than you think.
