lkjb QRange is a IIR linear phase EQ with the following features:

  • 12 bands (sortable by frequency).
  • Each band can be used as peak, shelf and cut filter.
  • Cut filters are available with 12, 24 and 48 dB/oct steepness.
  • Stereo/Left/Right/Mid/Side routing per band.
  • Global gain for loudness adjustments.
  • Resizable user interface.

The analyser can be set to analyse pre-EQ and post-EQ signal applying the same routings that are available per band. It is possible to adjust the analyser minimum/maximum magnitude by dragging the scale on the right (visible only if the analyser is active).

A menu which is available via the gearwheel provides:

  • Adjusting Analyser Range.
  • Adjusting frequency display magnitude.
  • Adjusting the plugin latency.
  • Setting a default EQ state and/or user interface size for new instances.

QRange uses IPlug-Youlean as plugin framework. From JUCE juce_core and juce_audio_basics modules are used.

Awesome plugin, thanks a bunch! That's an amazing level of functionaity and comfort for a freebie. I really like the sound from my first tests with it.

Does it generate different IRs from different latencies? I stick with "Insane" and it sounds great to me, but I wonder if I placeboed myself.
