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

Tweet embedding is no longer reliably available, due to the platform's instability (in terms of both technology and policy). If the Tweet still exists, you can view it here: https://twitter.com/foo_bar/status/1853167589301854584
Please note, though, that you may need to have your own Twitter account to access that page. I am currently exploring options for archiving Tweet data in a post-API context.
