Audacity defaults to rendering audio as stem plots now, when zoomed in. I found https://thewelltemperedcomputer.com/KB/SRC.htm https://thewelltemperedcomputer.com/KB/SRC.htm to be interesting. Near the bottom, it has sinc-interpolated visualizations of discrete-time signals (though saying that resampling is bad, because of a Nyquist-frequency signal not surviving an upsample and downsample, is misleading). What program is that?
