VHL-3C is a free vintage High / Low Pass Filter in AAX, VST, Audio Unit plugin formats. 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.
Authentic circuit emulation
Real time SPICE type component based circuit simulation approach allows to authentically capture the sound and feel of the analog counterpart in all nuances. Every crucial part of the passive filter network including filter stage interaction and the influence of different load resistances have been faithfully modeled.
SSE2 optimized code
DSP operations are pipelined using the SSE2 instruction set. This ensures highest possible performance operation despite very complex computations.
Auto-adjusted oversampling for maximum audio transparency
Aliasing artifacts are efficiently attenuated using a low latency linear phase Dolph-Chebyshev poly-phase design. The oversampling is auto-adjusted to your session‘s sample rate to save valuable CPU power while offering the most transparent sound possible.
