“TheExpressor is a colored upwards/downwards (Ex)pander/Com(pressor).
Key Features:
- Color – change slightly to soften the knee or boost/cut up to 24 dB for extreme emphasis.
- Extremely Low Aliasing – better quality than 6x oversampled plugins without the oversampling overhead or any delay*.
- Bounded – output is at most 6 dB louder than the input when Makeup is 0 dB.
