Absolute, Gauss and Power Filters

Absolute, Gauss and Power filters are quite frankly obscure and difficult to describe in any terms other than those which would only serve to make them sound even more obscure and difficult than they already are. Like any feature, I would not like to do without them, but by the same token, they are not likely to be called upon very often.Akin to the clip filter but with different "attack" characteristics and hence capable of generating a nonlinear response within the transition zones, with the exception of the power filter also have the capacity to reflect or flip at the extremities of the waveform so mimicking the sin filters double frequency response capability.
