Luftikus is a digital adaptation of an analog EQ with fixed half-octave bands and additional high frequency boost. As an improvement to the hardware it allows deeper cuts and supports a keep-gain mode where overall gain changes are avoided.


  • Hardware-modeled EQ.
  • 10, 40, 160 & 640 Hz bands.
  • 2.5 kHz shelf.
  • optional boost-only shelf at 2.5, 5, 10, 20 or 40 kHz.
  • Mastering and analog modes.
  • “Keep-Gain” option to avoid drastic overall gain changes when EQing.
  • Output trim to adjust gain.
  • Improved design to allow deeper cuts.

Luftikus is based on JUCE and open source (MIT licensed). Downloads and source code available on GitHub.


Luftikus can be downloaded on its kvr page.
