Used iin my saturated harmonic chord tutorial. These are not regular chebyshev exciters, the harmonic overtones are saturated. When used to create chords as in the tutorial this is like combining square waves instead of combining sine waves.
DOOM COMPRESSOR
Analyses the Input via - ENV - everything from -200db is expanded upwards
This is same as the other one but it blends input signal with compressed signal via env
Based on the nonlinear compressor but does the opposite. Uses the envelope follower to apply a nonlinear expansion. Rather than controlling the volume directly the envelope modifies the nonlinear transfer function to apply more or less loudness/saturation. When the envelope is low the transfer function is linear (low gain/saturation applied to quiet signals), when the evelope increases the curve is pushed towards a a heavy tanh saturation. So quiet signals are unsaturated and loud signals get saturated.
Based off nonlinear compressor but using assymetric shapes. Uses the envelope follower to apply a nonlinear pseudo-compression. Rather than controlling the volume directly the envelope modifies the nonlinear transfer function to apply more or less loudness/saturation. When the envelope is low a heavy tanh saturation is applied (which is like having a good ammount of gain going into the nonlinear compressor), when the evelope increases the curve is pushed down to a linear transfer function decreasing the loudness and the harmonics generated.
Thus, transients get the most clipping applied (high gain into the saturation prior to the envelope closing) - quiet parts of the signal get louder (low gain into the linear part of tanh brings up the volume) - loud sustained signals get less saturation (the transfer function goes towards a linear curve for sustained sounds - so their loudness is compressed).
