The High Pass effect module takes the difference between every sample and the preceding one, and stores this difference in place of each sample.
The equation is
y(n) = [x(n) - x(n-1)]/2,
where y is the output and x the input.
The response is that of a high-pass filter, with a zero at z=1 and a pole at z=0.
