I think youre thinking of self resonance (the oscilator like tune you get
from high resonance and non zero input).

zipper noise is an anoying buzzing sound you get when the recalcuation or
interpolation steps are too far apart, caused by discontinuities in the
amplitude curve, or sometimes first derivative of the amplitude.
