Out of bound noise, same as adding dither to a ADC to increase resolution.

Too the Extrema stuff specifically:

Extrema processing is covered by US patent 4,545,065.
Defunct Extrema Systems International Corporation (XSI);  Dr. Arie Visser.

The Extrema theory of human perception assumes that the ear distinguishes sounds
not by amplitude or frequency, but rather by timing and context.
Specifically, the ear
extracts only certain features of a signal- that is, the local minima
and maxima, or the extrema and passes to the brain the instances at
which they occur.  It doesn't matter whether it is minima or maxima, just
the change in direction of the signal is important.

I have been collecting reference about Neural 'Noise' for a while, you
can find those here:

Just added this reference as well:
