Waves have released a new plugin today, the Primary Source Expander aimed mainly at the live sound sector. PSE is designed to help you reduce stage bleed and sensitivity to feedback when a mic is idle by automatically lowering mic levels between musical phrases making it very useful for for live sound and for mixing live recordings.
At the heart of the Primary Source Expander (PSE) plugin is an expander, tailored especially for melodic sources such as vocals, guitars, strings, brass, woodwinds. PSE is designed to work like a fader that pulls back the channel’s level when the source goes below the threshold you’ve set. With PSE you can set both the threshold and the amount of attenuation.
PSE also provides advanced sidechain and ducking controls to help with treating complex live scenarios. Whether you are mixing FOH or monitors in a live venue or working on a live recording in the studio, PSE is designed to help you make sure that your mics are as loud and clean as they can be, while preserving your source’s original tone and the natural ambience of your location.
