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.
