Freq Shifter
This unusual effect is sometimes called “spectrum shifting” or “single sideband
modulation.” Frequency shifting shifts every frequency in the signal by a fixed number
of Hz which causes the harmonics to lose their normal relationship. The more
common pitch shifter, in contrast, preserves the harmonic relationships of the signal
and so is better suited to creating “musical” harmonies.
You can a lso typ e in
exact frequencies to a
resolution of 1/10 Hz.
This isn’t to say that the frequency shifter can’t be used musically. Small intervals of
frequency shifting (1 Hz and below) can produce a wonderful, lush chorusing or
phasing effect. For bizarre frequency shifting effects, simply crank up the frequency
knob. Frequencies can be shifted up or down by any specified amount from .1 Hz to 24
kHz. You can also shift pitch up on one side and down on the other if you wish.

Comparison between Pitch and Frequency Shifting
Parameter Description
Frequency Sets the number of Hz that will be added or subtracted with every
harmonic in the signal. Range: .01Hz to 24kHz
Left Direction Sets pitch shift up or down for the left channel.
Right Direction Sets pitch shift up or down for the right channel.
