apQualizr2 is a sophisticated audio plugin that combines a multiband equalizer with a frequency analyzer and modular effects system. It offers high-quality, low latency filters that cover the full frequency spectrum, making it ideal for a wide range of equalization tasks. The plugin includes graphical editing capabilities that allow precise control over filter parameters, supported by a zoomable FFT-based analyzer to visualize frequency content in real time.

Designed to enhance creative sound design, apQualizr2 features a modular modulation framework that lets users apply dynamic effects through LFOs, dynamics detectors, and other modules. This allows filter parameters to be modulated in complex ways, producing unique movement and tonal variation. Additional features such as mid-side and left-right processing per band, comb and spectral tilt filters, as well as harmonic filterbanks, provide extensive options for shaping audio with precision and character.

The plugin supports practical workflow enhancements like unlimited filter bands, undo/redo functionality, frequency band soloing, and sidechain input for dynamic control. It also includes an output clipper with gain reduction visualization and customizable color schemes to suit user preferences. Compatibility with importing equalizer configurations from other tools adds further flexibility, making apQualizr2 a powerful and adaptive solution for both mixing and sound design tasks.
