EVOC 20 Filterbank Parameters
The EVOC 20 Filterbank window is divided into three main sections: the Formant Filter
section in the center of the window, the Modulation section at the bottom center, and
Output section along the right side.
Formant Filter Section
The parameters in this section control the frequency bands in the two filter
banks: Filter Bank A and Filter Bank B.
 Frequency band faders: Set the volume of each frequency band in Filter Bank A using
the upper (blue) faders, and set the volume of each frequency band in Filter Bank B
using the lower (green) faders.
You can easily create complex bar curves by dragging horizontally across either row
of faders. This method makes editing multiple frequency band levels quick and
convenient.
 Frequency bar and fields: The blue bar above the upper row of faders controls the
overall frequency range for both filter banks. Drag the bar to move the entire
frequency range, drag the left end to move only the lower frequency (between 75
and 750 Hz), or drag the right end to move only the upper frequency (between 800
and 8000 Hz). You can also edit the numerical values above the bar directly (between
80 and 8000 Hz).
