What does Jitter sound like?

What a GREAT(!) question.

If I recall from a article it is inaudible to the human ear, give this article a read http://www.stereophile.com/reference/1093jitter/

It is like looking through a window that is fogged-up. HF noise mostly riding on the music. The spectrum and amplitude have a large effect on audibility, as does the system. If the system has a lot of sibilance from other sources, then it may be masked by this.

At its worst, jitter is revealed as a hard, flat, fatiguing glare across the midrange & treble. A low-jitter clock relieves strain and adds suppleness & body. Further reductions in jitter get closer to analog-like treble delicacy, tighter bass control, and overall ease. Sounds a little like a good massage...
