Phaser

A Phaser (or phase shifter) produces a fixed number of peaks and notches in the audio
spectrum which can be swept up and down in frequency with a low frequency oscillator
(LFO). This creates a swirly, ethereal sound with harmonically rich sound sources of a
type of pitch shift with simpler sounds. The phase shifter was invented in the 1970's and
the characteristic sound of this device evokes emotions of that musical era.

Parameter Description
Depth Controls how much the Center Frequency is swept by the LFO.
Range: 0% to 100%
Rate Controls the sweep rate of the Low Frequency Oscillator.
Range: .01Hz to 20Hz
Feedback Increases the depth of the notches and height of the peaks.
Inverted values invert the feedback polarity.
Range: -100% to +100%.
Stages Selects between: 3, 6, 9, or 12 phase shift stages and thus the
number of peaks and notches in the frequency response.
LFO L/R Phase Offsets the LFO between the left and right phaser channels.
(0°, 90°, or 180°). This adds animation to the sound.
