CHAPTER 20. LIVE AUDIO EFFECT REFERENCE 267

Phaser uses a series of all-pass lters to create a phase shift in the frequency spectrum of a

sound.

The Poles control creates notches in the frequency spectrum. The Feedback control can

then be used to invert the waveform and convert these notches into peaks (or poles). Filter

cutoff frequency is changed with the Frequency control, which can be adjusted in tandem

with Feedback using the effect's X-Y controller.

The device has two modes, Space and Earth, for changing the spacing of notches along the

spectrum, and hence the color of the sound. This effect can be further adjusted with the

Color control.

Periodic control of the lter frequency is possible using the envelope section. You can

increase or decrease the envelope amount (or invert its shape with negative values), and

then use the Attack and Release controls to dene envelope shape.

Phaser contains two LFOs to modulate lter frequency for the left and right stereo channels.

The LFOs have six possible waveform shapes: sine, square, triangle, sawtooth up, sawtooth

down and random. The extent of LFO inuence on the lter frequency is set with the

Amount control.

LFO speed is controlled with the Rate control, which can be set in terms of hertz. Rate can

also be synced to the song tempo and set in meter subdivisions (e.g., sixteenth notes).

The Phase control lends the sound stereo movement by setting the LFOs to run at the same

frequency, but offsetting their waveforms relative to each other. Set this to 180, and the

LFOs will be perfectly out of phase (180 degrees apart), so that when one reaches its peak,

the other is at its minimum.

Spin detunes the two LFO speeds relative to each other. Each lter frequency is then

modulated using a different LFO frequency, as determined by the Spin amount.

The Dry/Wet control adjusts the balance between the processed and dry signals. Set it to

100 percent if using Phaser in a return track.
