One thing that is clear, and this what got me thinking that way, is
that in Audacity, when zooming is done to see the actual sampling
points on a wave from a human voice sound, the line between two
sampling points is straight.
In Monty's video he *specifically* talked about how this representation of
digital samples is wrong and has confused so many people.
Now, with thousands of sampling points a
curve can be represented if one zooms out enough to see it as a curve.
The connecting straight line segment is an illusion and does not exist. You
are getting confused in the same way that Monty discussed.
I will say that I don't that he did a very good job of explaining this part
though. Sampled waveforms should never be drawn as "staircases", but should
be pointillistic. However to understand how this works, you need to
understand how the reconstruction filter works in a digital to analog
converter, and he didn't really describe this, and most people don't know
it either.
