HiLoFilter is a free filter VST, Audio Unit plugin developed by Teragon Audio. Compatible OS(s): Windows, macOS.
HiLoFilter is a simple hipass and lopass filter which can be easily controlled with a single knob. It is loosely inspired by the same type of filter found on some Pioneer DJM mixers, and also the The Pilgrim, another great plugin which provides roughly the same functionality.
