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.

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