Echo adds a set amount of delay to the signal passing through it and then mixes this delayed signal with the directaudio source signal. The delayed signal is always at unity gain. The level of the direct signal relative to the delayedsignal is set by the Delay Gain control as a factor between 0 (full attenuation of the direct signal), 1 (unity gain ofthe direct signal), and -1 (unity gain of the direct signal phase reversed).Comb FilterDelays the signal then feeds part of the delayed signal back to the input of the delay. Comb Filter has the samecontrol parameters as Echo, but the audible effect is quite different because it uses a feed backward rather than afeed forward signal path. The name Comb Filter comes from the fact that signals with a wavelength which is anodd multiple of half the delay time are canceled by the process. This result gives a frequency response chart whichlooks like a comb, with some frequencies (depending on the delay time) missing, like the gaps between the teethof a comb.All Pass FilterCombines the processes used in the Echo and Comb Filter effects. The result is a multiple echoed signal with a flatfrequency response. The control parameters are again the same as in the Echo and Comb Filter effects. Delay Gainhas a quite different effect. It doesn’t affect the overall level of the output signal. It primarily affects the phase ofthe signals at different frequencies. If set to 1, it inverts the phase of the input signal and there will be no echo.With a gain of -1, the input signal there is no phase shift. A gain of 0 means that there is no direct signal componentand the delayed signals are phase shifted by an amount dependent on their respective frequencies.FlangerThe flanger produces the characteristic sound which was first produced by playing two copies of something, insync but varying the speed of one copy by holding the flanges of the tape spool.Flanger floating WindowPyramix Flanger plug-in simulates this effect by time modulating the signal and feeding it back to the input eitherin phase (positive) or phase reversed (negative). Feedback type toggles between Positive and Negative. Depth ofmodulation can be varied between 0 and 100%, Frequency between 0.05Hz and 5Hz and the Amplitude of themodulation between 0 and 100%.Effects and Plug-Ins : Flanger 13 - 231
