but all he's asking is if you can hear where he made these shifts in this track. if you can (and as easily as you say), then where are they? it's pretty simple, and doesn't need to be so scientific and drawn out. in this simple case, why not just play along for the hell of it?
Audioconsult - that's a great explanation above, because the whole track could be full of computer-created jitter itself. (if i understand you correctly - is this right?)
(more to add in a bit...)
your gear list does not impress me.
