Sidechain Processing

Control how the sidechain affects compression behavior.

Sidechain HPF: 80 Hz

External Sidechain:

Internal External

Sidechain EQ: 0 dB @ 1kHz

Sidechain Effects

HPF at 80 Hz: Reduces low-frequency pumping and makes compression more sensitive to mid/high frequencies.

Common uses: De-essing (3-8kHz boost), vocal clarity (removing bass rumble), kick/bass separation (20-100Hz HPF).

RMS vs Peak Detection

Peak Detection RMS Detection

Peak Detection: Responds to instantaneous signal peaks. Fast response, good for transient control, can sound more aggressive.
