Remarks

The effect implements the auto-wah by using 4-stage phaser effect which moves a peak in the frequency response up and down the frequency spectrum by amplitude of input signal.

The fDryMix is the volume of input signal and the fWetMix is the volume of delayed signal. The fFeedback sets feedback of auto wah (phaser). The fRate and fRange control how fast and far the frequency notches move. The fRate is the rate of sweep in cycles per second, fRange is the width of sweep in octaves. And the the fFreq is the base frequency of sweep.
