Phaser

The Phaser FX sweeps a series of moving notches through the spectrum of the audio routed through it, producing a swirling, watery motion. Like all FX, it receives audio via Delay Lines or its external input channel.

Phaser Properties#

• Stages: The number of all-pass stages. More stages produce more notches in the spectrum: 4 is a classic Phase 90 sound, 8 is lusher, and 12 is extremely thick and watery.
• Rate: Speed of the phaser sweep. Slow rates give a long, swirling motion; fast rates produce a vibrato-like ripple.
• Depth: How wide the sweep moves around the center frequency. A value of 0 freezes the phaser at a fixed position, while 1 sweeps over a two-octave range.
• Center: The center frequency the sweep moves around. Lower values affect the low end; higher values shift the swirl into the brighter range.
• Spread: How widely the notches are spaced across the spectrum. A value of 1 stacks them on top of each other for a focused vocal sound; higher values spread them out for a swirling watery character.
• Feedback: How much output is fed back into the input. Positive feedback makes the notches sharper and more resonant; negative feedback makes them broader and more subtle.
• Width: Stereo width of the phaser. A value of 0 collapses to mono, 1 is natural stereo, and values above 1 over-emphasize the side channel.
