Comb Filter

Kilohearts

Comb Filter is a creative filter plugin that hollows out sound by carving frequencies at intervals of a base frequency, similar to the teeth of a comb. It works by mixing the signal with a delayed version of itself to create repeated troughs and peaks across the spectrum. The plugin also enables mono-compatible stereo widening through independent left/right channel processing.

Key Features

01Comb filtering with adjustable cutoff frequency
02Polarity control (plus/minus setting for peak/trough inversion)
03Stereo widening with mono compatibility
0431-band graphic EQ response pattern
05Dry/wet mix control

Things to Try

  • 01Flip the polarity setting to swap troughs for peaks and change the character at 0 Hz
  • 02Enable stereo mode to flip polarity on the right channel for stereo widening that collapses back to original when mixed to mono
  • 03Adjust the cutoff setting to change the distance between each peak and control the spacing of the comb filter teeth
