Ringshifter
Ringshifter overview
Ringshifter combines a ring modulator with a frequency shifter eect. Both eects were popular
during the 1970s and are currently experiencing a renaissance.
The ring modulator modulates the amplitude of the input signal using either the internal
oscillator or a side-chain signal. The frequency spectrum of the resulting eect signal equals the
sum of, and the dierence between, the frequency content in the two original signals. Its sound
is often described as metallic or clangorous.
The frequency shifter moves the frequency content of the input signal by a xed amount and
thereby alters the frequency relationship of the original harmonics. The resulting sounds range
from sweet and spacious phasing eects to robot-like timbres.
Note: Do not confuse frequency shifting with pitch shifting. Pitch shifting transposes the original
signal, leaving its harmonic frequency relationship intact.

parameters
Mode buttons: Determine whether Ringshifter operates as a frequency shifter or a ring
modulator. See Set the Ringshifter mode on page 195.
Oscillator parameters: Congure the internal sine wave oscillator, which modulates the
amplitude of the input signal in both of the frequency shifter modes as well as in the ring
modulator OSC mode. See Ringshifter oscillator parameters on page 196.
Delay parameters: Delay the eect signal. See Ringshifter delay parameters on page 197.
Envelope follower parameters: Modulate the oscillator frequency and output signal with an
envelope follower. See Ringshifter envelope follower modulation on page 197.
LFO parameters: Modulate the oscillator frequency and output signal with an LFO. See
Ringshifter LFO modulation on page 198 .
Output parameters: Set feedback, stereo width, and the amount of dry and wet signals. See
Ringshifter output parameters on page 199.
