FeedbackGuard
Adaptive Feedback Suppressor
$3.99
Get rid of feedbacks automatically. FeedbackGuard detects howling in real time and applies adaptive notches. Ready for live vocals, speech, and mobile rigs in e.g. AUM.
FeedbackGuard is an Audio Unit v3 effect that stops acoustic feedback before it ruins your performance. Whether you are singing live, speaking on stage, or recording vocals on iPad, FeedbackGuard listens for runaway howling and automatically places precise notch filters — so you can focus on the show, not the squeal.
HOW IT WORKS
FeedbackGuard uses PNPR (Peak-to-Neighbourhood Power Ratio) analysis combined with a growth check to tell real feedback apart from normal voice, speech, or room tone. When a howling peak starts to build, the plugin tracks it with parabolic peak detection and deploys an adaptive notch bank that reacts in milliseconds.
Designed for live use: attack and release times, suppression depth, and notch count are all under your control.
