EFFECT TYPES: PHASER
Phaser
Introduction
The electronic phasing effect is created by splitting an
audio signal into two paths. One path treats the signal
with an all-pass filter, which preserves the amplitude of
the original signal and alters the phase. The amount of
change in phase depends on the frequency. When
signals from the two paths are mixed, the frequencies
that are out of phase will cancel each other out,
creating the “notches” characteristic for a Phaser.
Changing the mix ratio changes the depth of these
notches. The deepest notches occur when the mix
ratio is 50 %, which is the fixed ratio of the Phaser in
NOVA Modulator.
DEPTH Knob
Use the DEPTH knob to specify the intensity of the
effect. The higher the setting the more aggressive the
effect will sound.
SPEED Knob
Use the SPEED knob to set the speed of the effect.
SHAPE/FEED Knob: Feedback Parameter
Use the SHAPE/FEED knob to control the amount of
feedback in the Phaser. Negative values inverse the
phase of the signal that is fed back to the algorithm’s
input.
