VHL-3C Free Filter Effect Plugin by Black Rooster Audio

Black Rooster Audio has announced the release of VHL-3C, a free vintage high/low pass filter effect plugin for Windows and Mac.

Built around a cascade of two constant-K filters the VHL-3C’s analog counterpart – a sought-after processor from the early 1950s – comprises an entirely passive design with very musical and interactive pass filters. Offering 3 simple and intuitive controls, the VHL-3C allows you to effectively remove rumble, hum or harsh frequencies from your signals.

Set both filter knobs to their extreme positions and you’ll end up with a narrow telephone-line bandpass. “So what?”, you may wonder – Black Rooster Audio is giving away this goodie for FREE!


  • Authentic circuit emulation
  • SSE2 optimized code
  • Auto-adjusted oversampling for maximum audio transparency
  • High DPI/ Retina support
