Phaser - Arturia VOCODER V User Manual

9.5.5. Phaser

Phase shifting, first popularized in the late 1960s, adds a swirling, animated character to
the sound. It works by splitting the incoming signal, modulating the phase of one split,
and recombining it with the dry signal. This creates one or more notch filters, whose notch
sweeps through the frequency spectrum, causing the phase shifter's signature "whooshing"
sound. This stereo phaser models analog phasers, but also includes tempo synchronization.
LFO Rate Sets the LFO speed. Enabling tempo synchronization (see below)
•
displays this parameter as a rhythmic value. Disabling synchronization displays
the Rate parameter in Hz.
Sync Locks the delay to the current song tempo in a DAW, or in stand-alone
•
mode, the Vocoder V's internal tempo (as set in Audio Midi Settings). With Sync
enabled, a tooltip appears when adjusting the Delay Time that shows the delay
as a rhythmic value. Disabling sync cause the tooltip to display the Delay Time in
milliseconds.
Rate Synced This is active only if Sync is enabled, and further defines the
•
rhythmic value as Binary (standard rhythmic values), Ternary (triplets), or Dotted.
LFO Amount Sets the strength of the LFO's modulation, with more modulation
•
sweeping the notch filters over a wider frequency range.
LFO Shape Sets the wave shape of the modulating LFO. Choices are Sine,
•
Triangle, Saw, Ramp, Square, and Sample and Hold (random).
Frequency Sets the center frequency around which the phaser modulation
•
affects the incoming signal.
Feedback Controls the resonance of the Phaser's filters. Caution: Higher settings
•
can make the filtering effect very pronounced.
N Poles Sets the number of poles used in the sweeping filter. Lower settings
•
sweep fewer notch filters for a subtler sound, while higher settings sweep more
filter notches for a more dramatic effect.
Stereo Sets the effect's stereo width, from mono to maximum stereo (i.e., the
•
stereo image covers the range from all the way left to all the way right).
