The filter component sits in between the filter delay and reverb modules. It is a variable filter that can be set to different types.

The available types are:

  • Low pass
  • High pass
  • bandpass
  • notch
  • peak
  • low shelf
  • high shelf

The filter type can be changed using the filter type button.

The controls modify the cutoff frequency, the resonance around that frequency and the gain control is used for peak and shelf filters, and adjusts the gain in decibels.

The filter was placed after the filter delay effect in order for a final sculpting of the frequency spectrum before the audio enters the reverb module.
