CHAPTER 19. LIVE AUDIO EFFECT REFERENCE 233
The LFOs have six possible waveform shapes: sine, square, triangle, sawtooth up, sawtooth
down and random. The extent of LFO inuence on the delays 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 delay is modulated at a
different frequency, as determined by the Spin amount.
Adjusting the HiPass control will cut low frequencies from the delayed signal.
The Dry/Wet control adjusts the balance between the processed and dry signals. Set it to
100 percent if using Flanger in a return track.
19.13 Gate
The Gate Effect.
The Gate effect passes only signals whose level exceeds a user-specied threshold. A gate
can eliminate low-level noise that occurs between sounds (e.g., hiss or hum), or shape a
sound by turning up the threshold to where it cuts off reverb or delay tails or truncates an
instrument's natural decay.
