SUS4 Expander

Downward expansion for gentle room rejection without gating artefacts. Sus expands the wrong way on purpose.

Included in the SUS4 plugin bundle. One licence, every plugin, every update.

Downward expansion for gentle room and bleed rejection without the hard edges of a gate. Push the noise floor down between phrases while keeping the tails natural.

The subtle way to clean up a vocal, a tom or a DI without anyone hearing a gate slam.
