apulSoft apQualizr2
Modular Equalizer Audio Plugin
apulSoft apQualizr2 is an audio plugin based on a multiband equalizer layered on top of a frequency analyzer with elements of a modular effects system. It features graphical editing of top quality low latency filters and modular modulation of various filter parameters. It can be used for all standard EQ applications and can produce many modulation and dynamics effects thanks to the dynamics and lfo modules included. Additionally filter bands can be controlled by midi keyboards and controllers thanks to a built in midi module.

apQualizr2’s filters are based on a unique method to match ideal frequency response curves over the entire frequency spectrum while maintaining minimal latency. Applicable filter types have adjustable steepness (adjustable number of poles/slopes) and can be individually switched to Mid-Side processing. Since version 2.2, filters have a ++ poles mode where slopes get very steep and the full gain change is covered within one semitone.
