The Primary Source Expander Black Friday deal from Waves takes 62% off this utility plugin built to control mic bleed in live sound, which brings it to $29.99 until Nov 26, 2026.
Primary Source Expander, or PSE, is an expander aimed at the problems that pile up when you mix a live show. Waves describes it as easy to use and optimized, and says it clears most issues instantly.
The maker also says it can handle the toughest bleed problems.
The maker lists three situations it was built for. Mic bleed can cause feedback that stops you from turning up the PA. You may have to keep muting background noise when a singer isn't singing. Or you may need clean isolation on a live multitrack recording.
An expander lowers the level of a channel when the signal falls below a threshold. That is the job here, applied to open mics on stage.
Waves lists these as the headline benefits:
That last point matters if your work is speech. Several open lav mics on one panel are a bleed problem too.
PSE offers internal and external sidechain, each with HP/LP filters. If you use a different signal to trigger the expander, the external input is there for that.
A ducking mode adds precision in complex live scenarios. Release time presets are included to speed up your process, so you can recall a setting instead of dialing in every release by hand.
On Mac, the plugin supports macOS Monterey 12, Ventura 13, Sonoma 14 and Sequoia 15, in VST, AU and AAX formats.
On PC, it needs Windows 10 or later and comes in VST and AAX formats.
If you run a Mac-based live rig in the AU format, or a Windows machine in AAX, both are covered.
