Description

Quad Anti Aliasing Filter (QAAF).

4 independent filters in one seamless module

The WMD Quad Anti Aliasing Filter(QAAF) was conceptualized as the firstexpansion for the Phase Displacement Oscillator.

It is designed to eliminate aliasing and stair-step distortion fromthe Digital to Analog converters. Weopted to make this a seperate modulebecause it is useful by itself as well ascoupled with the PDO.
