So it sounds like bad vinyl or that "six-million-dollar man" (anybody remember Steve Austin ) type sound then?

I was reading in a DaD comment on a DVD rip about how diginoise was heard and then confirmed in a wave editor. Is the confirmation possible? Static and effects like echo don't seem to me to have a "signature" but then I still have to get grip on what frequency analysis is (intuitively I'd say it's a distribution of the signal into frequencies and their strength/intensities)

Thx for any answers/tips/comments.
