Well done, I enjoyed reading it.

Just one remark: dithering has nothing to do with aliasing,
and it certainly doesn't 'mask' it.

It is used to remove the distortion that could result from
quantisation (i.e. using a finite number of possible values
for each sample). More accurately, dithering doesn't mask
such distortion (in the sense of 'hiding' it), but converts
it into noise.
