Public Attributes
double	amount = 0.0
	Blend from clean (0) to fully shaped (1). Exactly 0 is a bit-exact bypass.
double	drive = 1.0
	Pre-gain into the saturator. Higher drive = harder curve = more harmonics.
double	asymmetry = 0.0
	Even-harmonic bias.

Detailed Description

A per-shape lumped memoryless nonlinearity — the "analog character" the output stage imprints.

One curve stands in for the whole waveshaper/soft-clip chain of a shape (the identifiability table's "output soft clip vs shaper residual" pair is observationally one nonlinearity per shape at a fixed level, so this increment fits one lumped curve, not the split).

Neutral by default (amount == 0 → identity, applied as an exact bypass).

Member Data Documentation

amount

double pulp::signal::osc::WaveshaperParams::amount = 0.0

Blend from clean (0) to fully shaped (1). Exactly 0 is a bit-exact bypass.

asymmetry

double pulp::signal::osc::WaveshaperParams::asymmetry = 0.0

Even-harmonic bias.

0 is symmetric (odd harmonics only); non-zero pulls the curve off-center and introduces even harmonics.

drive

double pulp::signal::osc::WaveshaperParams::drive = 1.0

Pre-gain into the saturator. Higher drive = harder curve = more harmonics.
