apQualizr2

modular equalizer plugin
fantastic sound quality
countless modulation possibilities
Overview

apulSoft apQualizr2 is an equalizer audio plugin. Filter bands can be graphically edited on top of a frequency analyzer display. The module tray enables module-based modulation of various filter parameters.

apQualizr2 can be used for all standard EQ applications. It can create modulation and dynamics effects thanks to the included dynamics and super-flexible lfo modules. The built-in midi module provides midi control of most things.

Filter Technology
apQualizr2 filters are based on a unique method to match ideal frequency response curves over the entire frequency spectrum.
Applicable filter types have adjustable steepness (adjustable number of poles/slopes) and can be individually switched to mid-side processing
Filters have a ++ poles mode where slopes get extremely steep: the full gain change is covered within one semitone.
Spectral tilt and variable-slope low- and highpass filters allow continuous tilt/slope values and modulation.
apQualizr2 includes phase correction engines to achieve minimal, analog, mixed and linear phase.
