FXAlg #727: PolyD EQ
Eight-stage distortion followed by equalization
Allocation Units:
2
PolyD EQ is a distortion algorithm followed by equalization. The algorithm consists of an input gain stage,
and then eight cascaded distortion stages. Each stage is followed by a one-pole LP filter. There is also a one pole
LP in front of the first stage. After the distortion there is a 4-band EQ section: Bass, Treble, and two Parametric Mids.
