Jaycen Joshua employs the Avid Dynamics III gate to manage noise on the drum bus.
He sets the gate with a very low threshold, ensuring it remains inactive while the drums are playing, thus preserving the natural sound and dynamics. However, once the drums stop, the gate gradually closes with a one-second release, effectively reducing any noise floor caused by extensive compression and plugins.
This technique is an easy way to maintain a clean mix, and can be applied to other instruments or effects returns to prevent unwanted noise from creeping into the mix during silent passages.
