I will, however, observe that your definition of a square wave is

cycle, as in

That is a square wave.

as opposed to your

That isn't.

Arguing to the contrary is just being Humpty Dumpty...
Neither I nor Steve has called that latter wave a square wave.

Steve, quoted above, has written that I defined a square wave that way.
I have not. So Steve's statement is a misrepresentation (I described it
as a sum of two square waves, which it is), whatever the reason for that
misrepresentation.



[snip]
So here you have an interesting example of a
piece of code that is pathological in Python2. All you have to change is
to add

  from __future__ import __division__

and bingo! It's a multi-language program. But try seeing what 2to3 says
about your Python3 code :)

I will forgive you the omission of the ".0" because I too would assume
that it would be slower.

I did not make any such assumption, no. The *1 just lingered from some testing.

and so on, but I still get silence from the Quicktime player.

I don't know, sorry.

It might be that [simple_sound] also needs the "from __future__" treatment.

But anyway, with 2.x compatible code you can now see that the sample values produced are correct (just print them, or graph them).


Cheers & hth.,
