How AlexFeedback works
Three stages, all on your Mac, all in real time.
Listen
A high-resolution spectral analysis runs beside the audio path and tracks every prominent peak - 187 times per second.
Decide
A neural network trained on real howls and real programme material judges each peak: growing feedback or a note, a vowel, a resonance?
Notch
Only confirmed feedback gets an ultra-narrow, click-free notch that deepens as needed and releases when the ring is gone.
Built for the stage
Everything runs locally on your Mac - no cloud, no added latency.
AI Feedback Detection
A neural network classifies every spectral peak in real time: feedback or music? Trained on real howls and real programme material.
Ultra Low Latency
Zero samples of added latency. The analysis runs beside the audio path, never in it.
Adaptive Notch Filtering
Ultra-narrow notches that appear, deepen and release automatically - click-free and sample accurate.
Up to 48 Filters
Dozens of simultaneous notches for stubborn rooms and open monitor mixes.
Designed for Live Audio
One knob. Filter Strength from conservative to maximum. No menus during the show.
Apple Silicon Native
Optimised for M-series Macs. AU and VST3, one activation for both.
Local AI Processing
The model runs on your CPU in microseconds. No cloud audio processing, ever.
Works Offline
Activate once, then run shows without internet. Re-validation happens quietly in the background.
One screen. Everything you need during a show.
Bypass, Filter Strength, live confidence and a spectrum that shows exactly what is being notched.

Insert AlexFeedback on a channel, a monitor bus or the main out.

Stop chasing feedback. Start mixing.
Try the demo in your next rehearsal - if it saves you one ring during the show, it has paid for itself.
