QAAF Quad Anti-Aliasing Filter - 4HP

WMD QAAF

The WMD QAAF (Quad Anti Aliasing Filter) is an expansion for the PDO intended to do away with aliasing and distortion that sometimes plagues digital to analog converters. The module can be used in tandem with the PDO, or separately as its own self-contained module. 

The QAAF features four independent -24dB/octave Butterworth filters that run at the same frequency with a slight pinch of resonance.

Additionally, the module’s frequency control circuitry is vactrol-controlled, meaning the filter response is slowed in response to transient signals, adding fundamental amounts of character to any sound.
