This may be naive, but I thought it did not apply because in Audacity, at that zoom in level, it really does not look like a staircase at all, here for an acoustic solo guitar waveform. Even though the lines between points are straight, they are following curves. See attached. So I thought his staircase was a gross representation that did not apply. > The connecting straight line segment is an illusion and does not > exist.

I was wondering about this. In extremely simple terms I think that capacitors smooth out curves.
