Function [up] [down]
Dampens/boosts the signal. The filter coefficients are taken from src 2. Therefore src 2 controls all the parameters like filter type (lowpass, highpass, ...), the cut-off frequencies, the filter slope and so on.

Parameter [up] [down]
Effect (P1)how much the operator effects the outcome
Filter-Offset (P2)Modulates the point in the scr 2 sample, where the operator startsretrieving the filter coefficients.
Filter-Stretch (P3)Modifies the mapping from samplevalues to coefficients.
Window (W1)what windowfunction to use
Nr. (Length)How many coefficients should be used. The more they are, the better results will be get.(max 1024, but 64 is usually enough)
Interpolation (I1)how to calculate (smooth) inbetween data
Ampffinal amplification

Notes [up] [down]
A filter such as this, is more an experimental thing. There is nearly no way to know the result before. Good results are achived by e.g. changing the filter-offset very little (e.g. linear from 0.0 to 0.1) or using a relativ short sample for scr 2. Furthermore it sounds interessting to blend the filter-stretch from e.g. 0.125 to 8.0.
Curved-interpolation is useful, when using very short sample for src 2 or small filter-offset changes.
