Found it! I was thinking of a presentation I'd seen somewhere, where the details of inter-sample peaks is properly explained: Slide 22 of Fons' EBU loudness meter presentaton (given at LAC2011 Maynooth, by Jorn Nettingsmeier):

The wave is pretty much predictable: until a (strange) *double 1.0* value sample appears. The D/A conversion goes crazy, a spike to value of approx 3, while the range should be -1 to 1.
The worse thing is, the longer this "predictable" part is, the *higher* the spike gets.
