Dub Filter by AudioThing is an audio effect plugin, specifically a high-pass filter modeled after King Tubby’s iconic Big Knob, a passive high-pass filter with eleven frequency steps ranging from 70Hz to 7.5kHz ([audiothing.net](https://audiothing.net/effects/dub-filter)). It is designed to emulate the sound of vintage Jamaican dub music and is primarily used as an audio effect rather than an instrument or synth ([pluginboutique.com](https://www.pluginboutique.com/product/2-Effects/19-Filter/121
