EVOC 20 Filterbank
The EVOC 20 Filterbank consists of two formant filter banks, which are also used in the
EVOC 20 PolySynth vocoder plug-in.
The input signal passes through the two filter banks in parallel. Each bank features
volume faders for ten frequency bands, allowing you to adjust the volume of each
band independently. Setting a fader to its minimum value completely suppresses the
formants in that band. You can control the position and width of the filter bands using
the Formant Stretch and Formant Shift parameters. In addition, you can also crossfade
between the two filter banks.
For more information on filter banks, refer to “How Does a Filter Bank Work?” on
page 151.
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.
