Recti-Fi Controls
Recti-Fi Pre-Filter Control
The Pre-Filter control filters out high frequen-
cies in an audio signal prior to rectification.
This is desirable because the rectification pro-
cess can cause instability in waveform output—
particularly in the case of high-frequency audio
signals. Filtering out these higher frequencies
prior to rectification can improve waveform sta-
bility and the quality of the rectification effect.
If you wish to create classic subharmonic syn-
thesis effects, set the Pre-Filter and Post-Filter
controls to a relatively low frequency, such as
250 Hz.
The range of the Pre-Filter is from 43 Hz to
21 kHz, with a maximum value of Thru (which
effectively means bypass).
Recti-Fi Rectification Controls
Positive Rectification This rectifies the wave-
form so that its phase is 100% positive. The au-
dible effect is a doubling of the audio signal’s
frequency.
Negative Rectification This rectifies the wave-
form so that its phase is 100% negative. The au-
dible effect is a doubling of the audio signal’s
frequency.
