Original Note:
Digital sound waves are not stair steps. Digital-to-analog conversion *perfectly* reconstructs the original analog signal as a smooth wave, including all frequency components up to 1/2 of the sampling frequency. This follows from the Nyquist-Shannon sampling theorem. https://www.youtube.com/watch?v=cIQ9IXSUzuM https://en.wikipedia.org/wiki/Nyquist–Shannon_sampling_theorem
