lkjb QRange is a linear phase equalizer featuring 12 adjustable bands that can be individually configured as peak, shelf, or cut filters with selectable steepness levels. Each band supports stereo, left, right, mid, or side routing, allowing detailed control over the audio spectrum. The plugin includes a global gain control for loudness adjustments and offers a resizable user interface to suit various workflows. Recent updates introduced Gain Match functionality and a latency-free minimal phase mode that enhances performance without adding delay.

The integrated analyzer provides flexible monitoring by allowing users to switch between pre- and post-EQ signal analysis, with adjustable magnitude scales for precise visualization. This feature supports the same routing options as the individual bands, making it easy to track the impact of EQ adjustments in real time. A dedicated settings menu lets users customize analyzer range, frequency display magnitude, plugin latency, and default states for both the EQ and user interface size, streamlining the setup process for new instances.

Built on the IPlug-Youlean framework with additional support from JUCE modules, lkjb QRange benefits from robust performance and compatibility. The plugin has undergone several updates to enhance stability and usability, including fixes for low-frequency distortion, improved graphical display options, and better integration with popular DAWs like Cubase, Logic, and Ableton Live. These continuous improvements ensure that QRange remains a reliable tool for precise equalization across diverse production environments.
