727 PolyD EQ
Eight stage distortion followed by equalization
PAUs:
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
fi
lter. There
is also a one pole LP in front of the
fi
rst stage. After the distortion there is a 4 band EQ section: Bass, Treble,
and two Parametric Mids.
