Bedroom Producers Blog has announced the release of the BPB Dirty Filter, a freeware tube distortion effect plugin for Windows and Mac.
It features a pair of resonant filters that can distort a specific area of the frequency spectrum. In a way, BPB Dirty Filter is similar to multi-band distortion but with a more straightforward workflow. Choose a frequency that you’d like to distort and increase the Drive parameter to add resonance and tube saturation.
When the Drive knob is set above 50, BPB Dirty Filter transforms into a powerful distortion effect. Use high amounts of distortion in tandem with the Mix knob to keep some of the original audio. 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.
BPB Dirty Filter features
- High-pass filter (20 Hz – 20 kHz).
- Low-pass filter (20 Hz – 20 kHz).
- Adjustable slope (12, 24, 36, or 48 dB/octave).
- Tube distortion.
- Mix (0 – 100%).
- Output volume (±12 dB).
The plugin is a free download in VST/VST3, AU and AAX formats for Windows and macOS.
