Phaser
Phaser is a modulation effect based on splitting the signal into two paths and changing the
phase of one of them using all-pass filters. When both signal paths are mixed together some
frequencies appear to be out of phase and cancel each other. This process creates notches
and peaks in a frequency response. These notches can be moved up and down the frequency
range if filter’s phase shift is controlled by a low-frequency oscillator. This effect block
contains the following parameters:
•
Mix:
Controls the balance between
Dry
and
Wet
signal. The most pronounced notches
occur when the
Mix
ratio is 50% (D+W 0).
You can assign a controller to this parameter. Use
Phaser Volume
as destination.
Range: Dry 63 to Wet 64.
•
Rate:
Sets the
Rate
of the low-frequency oscillator (LFO), making the effect slower or
faster.
You can assign a controller to this parameter. Use
Phaser Rate
as destination.
Range: 0 (0.048 Hz) to 127 (4.85 Hz).
•
Center:
Sets the frequency the notches will be moving around.
Range: 0 (80 Hz) to 127 (12 kHz).
•
Width:
Controls the amplitude of the LFO, widening or narrowing the effect.
Range: 0 to 127.
•
F_Back:
Feeding some of the filter’s output back to its input increases the contrast
between the peaks and the notches, resulting in increased saturation of the effect.
Range: 0 to 127.
