Vibrazum features three independent, 2-pole bandpass filters, with a slope of -12dB per octave.
They share a common audio input, allowing to use the module as a formant filter. Each filter provides an individual output. Furthermore, the three channels are summed at the Mix output with individual level controls.
The cutoff frequency of each filter is adjusted manually with the first potentiometer on the left. Thanks to the CV Freq input it can be voltage controlled. Each channel is able to sweep the entire frequency range for everything from modulated snarls, nasal sweeps, and pseudo-resonator response.
The second knob sets the feedback, respectively the resonance of each filter. It can be voltage controlled via the CV Fdbk input. The feedback is able to resonate in the low frequencies.
