Phase Shifter
A phase shifter produces a fixed number of peaks and notches in the audio spectrum
which can be swept up and down in frequency with a low frequency oscillator (LFO).
This creates a swirly, ethereal sound with harmonically rich sound sources of a type of
pitch shift with simpler sounds. The phase shifter was invented in the 1970’s and the
characteristic sound of this device evokes emotions of that musical era.

By setting the LFO Depth to zero and tuning the LFO Center, a fixed multi-notch filter is
created.
