This is a useful exposition, but in practice, what you may get is:

  1 @ -0.0001
 -1 @  1.0001
  1 @  2.00001
 -1 @  2.99999

the question is, does this make any difference ? These jitters are measured
in picoseconds. There are 22 675 737 picoseconds between samples at 44.1
kHz.

In the digital domain, it is easy to measure the jitter with suitable
equipment. Is there ANYTHING (other than a golden ear) that can measure a
difference in the analog output from the D/A as a result of this jitter,
even if it isn't reclocked ?
