de.sciss.synth.ugen
A two point difference filter UGen. Implements the formula :
out(i) = 0.5 * (in(i) - in(i-1))
Note: the filter's memory is initialized with the first input sample, so for HPZ1.ar(DC.ar(x)) the output will be zero, even at the beginning.
Note:
HPZ1.ar(DC.ar(x))

Abstract method which must be implemented by creating the actual UGens during expansion.
