It’s a Free Filter

It’s a Versatile Filter

Featuring a high-pass and a low-pass filter combo, BPB Dirty Filter is a useful utility for cleaning up your audio. Both filters have a range between 20 Hz and 20 kHz and the filter slope can be set to 12, 24, 36, or 48 dB/oct. The plugin also features a Mix knob and an output volume control for easy gain staging in your DAW.

It’s a Dirty Filter

With the Drive knob set to zero, BPB Dirty Filter operates as a transparent filter plugin. In this mode, it is great for cleaning up low-frequency hum or removing high-frequency noise. However, push the Drive knob to a higher setting and BPB Dirty Filter transforms into one of the most hardcore distortion plugins around.

BPB Dirty Filter is a creative effect built for sound designers. And although it can be used as a well-behaved filter, this wild little plugin was born to apply unhealthy amounts of dirt and grit to your audio. Think of it as a versatile distortion pedal with a wide range of tones. Pick any frequency range and add any amount of distortion to it, from subtle tube saturation to earth-shattering audio destruction.
