Microphone bleed control in live mixes

Waves Primary Source Expander (PSE) is the ideal plug-in for those working in the live sound world. It eliminates background noise and unwanted returns with automated and effective handling, so you can focus on creativity instead of troubleshooting.

Precision and musicality for every performance

Intelligent expansion for melodic sources

PSE smoothly lowers signals below the set threshold while keeping musical quality intact. Perfect for vocals, guitars, strings and more, without the artifacts of traditional noise gates.

More volume, less feedback

Bleed can cause feedback and phase problems. PSE enables superior gain-before-feedback, also improving monitoring for musicians on stage.

Advanced control with sidechain

With internal or external sidechain with HP/LP filters, and ducking mode, you can precisely handle even the most complex acoustic situations.

Set-and-forget for smoother shows

PSE is designed to be simple: you set threshold and range, and it does the rest. Working live has never been cleaner or faster.
