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. KEY FEATURES • Real-time howling detection (PNPR + run-up check) • Adaptive notch bank — up to 24 simultaneous notches • Live spectrum display with active notch markers • "Balanced" preset for safe, transparent defaults • 3 user preset slots — tap to recall, hold to save • Fine-tuned controls: Sensitivity, Notch Threshold, Suppression, Q, Attack, Release • Optional harmonic tracking for stubborn feedback tones • Optional spectral noise reduction for quiet passages • Full bypass GET STARTED IN SECONDS 1. Open your AUv3 host (GarageBand, AUM, Cubasis, and more) 2. Insert FeedbackGuard as an audio effect on your vocal or monitor channel 3. Tap "Balanced" for recommended live settings 4. Raise Notch Threshold if notches appear on voice or room tone IDEAL FOR • Live vocals and speech • Rehearsals, worship, small PA setups • Mobile recording rigs on iPhone and iPad • Any situation where monitor feedback is a risk COMPATIBILITY • Audio Unit v3 (aufx) effect • iPhone and iPad • Works in any AUv3-compatible host • Mono or stereo, sample rates from 8 kHz to 192 kHz FeedbackGuard — Adaptive Feedback Suppressor by Norwin Palme.

Give tracks presence without flattening the source. Add air, articulation, and density through a tuned parallel path. AE975 is an AUv3 audio effect for subtle polish, forward detail, and playable control. AE975 keeps the dry signal as the foundation, listens to a Focus-controlled sidechain, generates source-derived harmonic texture, and blends the result back in parallel. The goal is mix-ready lift without treating brightness like a simple EQ boost. Sound-shaping controls: - Focus sets the responsive region from 600 Hz to 6 kHz, with 3 kHz at center. - Enhance controls the parallel return depth. - Texture changes harmonic color and complexity. - Saturation adds intensity inside the enhancement generator, not as a full-band clipper. - Density moves from clean transient sparkle to smoother sustained glow. - Mix, Output, and Bypass make level-matched comparison simple. Built for DAW workflows: - Use AE975 as an audio effect in compatible AUv3 hosts. - Open the standalone companion host app to audition the processor with generated test audio, or compatible hardware I/O. - Browse 92 categorized factory presets for mastering, mixing, buses, vocals, guitars, bass, drums, synths, strings, brass, woodwinds, and sound design. - Save user presets locally and mirror them with iCloud preset sync. - Map hardware controllers with MIDI Learn, direct CC assignment, reset-to-default controls, and feedback broadcast support. Use it when a vocal needs to read forward, drums need more snap, guitars need pick detail, synths need shine, strings need rosin, buses need polish, or a master needs a controlled final lift.
