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.

A world of exhaustive, reliable metadata would be an utopia.

It's also a pipe-dream, founded on self-delusion, nerd hubris

and hysterically inflated market opportunities. (Cory Doctorow)
