Frequently Asked Questions

When sound leaks back into open microphones, bleed, room reverb and feedback build on one another. The tools available today often can’t fix it quickly and precisely enough in the middle of a live show, so Feedback Guardian AI was built to make that work easier: Clean Bleed, Clear Resonance, Cut Feedback.

It was developed from data collected in real situations — live music performances and speaking events — with one main goal: to be as easy to use as possible.

• Clean Bleed — reduces cymbal, drum and instrument spill.
• Clear Resonance — reduces room reverb and standing waves.
• Cut Feedback — stops howl before it builds in the PA.

No. It works in real time with no added delay — the added latency is listed as 0 ms (Zero Latency) on all platforms.

No. It is fully automatic: intelligent processing, with no setup needed.

Yes. Speech and Singing are both listed among its input signal modes. The feature list also includes Auto Mix, Feedback Reduction, Bleed Reduction, Reverb Reduction, Fully Automatic and Zero Latency.
