But this only proves how false a squarewave is. Lets take another tack. Does
the brain actually hear a square wave?
The answer has to be no, as we are using mechanical devices to transfer the
pressure differences from an electronic signal to the brain, and if there
is already no such thing as a rise time and fall time of zero, then in a
room with speakers with mass and all the implications of air compression
and the ear drum, another mechanical device, the heard shape is going to
probably be more like a sine wave with some harmonics at audible
frequencies.


Has anyone actually built an artificial ear and processor, remembering of
course the inherent nonl linearity of the way the signal is processed, and
of course the amazing echo nulling out of the ears/brain system!

If you do do this, you actually still cannot listen to it, only look at it,
as we do not, yet, have a gold plated phono input to our brain.

And what do your ears top-out at?

Clear enough?

I said nothing about audibility, or not. I was SPECIFICALLY referring to
the square wave capability of the different formats. I was careful enough
to specify the frequency too. MY ears are not under dicussion. The
relevant performance of the cited formats is.
