Delay
uses a straight-through signal path at unity gain with no direct (un-delayed) signal present at the output.
The length of delay can be set in milliseconds, meters or samples. The range of delay available is 0 to
800 ms. Delay time can be set with the knob, or by typing in the desired delay amount in the text box.
Echo
Echo adds a set amount of delay to the signal passing through it and then mixes this delayed signal with
the direct audio source signal. The delayed signal is always at unity gain. The level of the direct signal
relative to the delayed signal is set by the Delay Gain control as a factor between 0 (full attenuation of
the direct signal), 1 (unity gain of the direct signal), and -1 (unity gain of the direct signal phase
reversed).
Comb Filter
Delays the signal then feeds part of the delayed signal back to the input of the delay. Comb Filter has
the same control parameters as Echo, but the audible effect is quite different because it uses a feed
backward rather than a feed forward signal path. The name Comb Filter comes from the fact that sig-
nals with a wavelength which is an odd multiple of half the delay time are canceled by the process. This
result gives a frequency response chart which looks like a comb, with some frequencies (depending on
the delay time) missing, like the gaps between the teeth of a comb.
All Pass Filter
Combines the processes used in the Echo and Comb Filter effects. The result is a multiple echoed sig-
nal with a flat frequency response. The control parameters are again the same as in the Echo and
Comb Filter effects. Delay Gain has a quite different effect. It doesn’t affect the overall level of the output
signal. It primarily affects the phase of the 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 component and the delayed signals are phase shifted by
an amount dependent on their respective frequencies.
Flanger
The flanger produces the characteristic sound which was first produced by playing two copies of some-
thing, in sync but varying the speed of one copy by holding the flanges of the tape spool.
Pyramix Flanger plug-in simulates this effect by time modulating the signal and feeding it back to the
input either in phase (positive) or phase reversed (negative). Feedback type toggles between Positive
and Negative. Depth of modulation can be varied between 0 and 100%, Frequency between 0.05Hz
and 5Hz and the Amplitude of the modulation between 0 and 100%.
