It seems pretty obvious to me he means varying peak amplitude with
each cycle.

That's completely contrary to the context of the thread, which relates to
sample-by-sample amplitude.


It seems to me to be what Scott W. meant by varying amplitude. If that is what
he means, and I am confident it is what he means then it seems to me that it
will make a difference in how accurately one can plot a wave form using so few
samples per cycle. It also is the reality of music. Not a lot of sin waves with
no variation in peak amplitude in music. No doubt though, if one wants to
listen to sin waves with steady state peak amplitudes, digital should do a much
better job than analog.
