Before using the e2deesser, this is important to understand the signal routing, which is pretty simple. The incoming signal is routed to three different units:
- The Sibilants Detection algorithm, set by the Mode and controlled by the Sensitivity
- The Sibilants processing (i.e. Sibilants EQ, Sibilants Wide Band Gain, Auto and Smooth), governed by the Amount
- The Voiced processing (i.e. Voiced EQ)
When the Sibilants Detection algorithm doesn’t detect Sibilants, the e2deesser outputs the processed Voiced path only. When the Sibilants Detection algorithm detects Sibilants, the e2deesser outputs the processed Sibilants path only. See the following diagram which illustrates this signal routing.
