For all of those out there who insist upon praising CDism and
their (non)square waves by relying on the FFT sine-wave generation
approach have missed something intrinsic in their approach.
 
This method will produce a 'square' wave with maximal distortion
at the points of the square, not a uniformly decaying sine wave
distortion. 
 
So... for the sake of arguement... lets say that your arguements
are correct and I am wrong.
This leads to the FACT thay you are not explaining the type
of error that is shown in 'Audio' and their ever-present
oscilloscope tests at 1KHz.
 
In fact, you are predicting an entirely different kind of error.
