TheExpressor is a colored upwards/downwards (Ex)pander/Com(pressor).

Key Features:

1. Color - change slightly to soften the knee or boost/cut up to 24 dB for extreme emphasis.
2. Extremely Low Aliasing - better quality than 6x oversampled plugins without the oversampling overhead or any delay*.
3. Bounded - output is at most 6 dB louder than the input when Makeup is 0 dB.
