bx_cleansweep is a Hi-Pass filter and Lo-Pass filter plug-in featuring "Anti Crush Technology". It offers analog-style filter curves, without the typical Nyquist problems, in a filter design taken from Brainworx's pro mastering EQ bx_digital V2. First order filters (6 dB) guarantee a musically sounding filter set and unique joystick control (taken from bx_hybrid) gives you fast and intuitive control.
