X-FDBK

X-FDBK is a feedback-fighting utility plugin from Waves that automatically detects and notches out the frequencies causing feedback in live sound setups. Instead of manually hunting for problem frequencies, it analyzes incoming audio and applies up to 20 precise notch filters, intelligently adjusting bandwidth and cut depth. The result is clearer, louder monitor and PA sound with several dB of extra headroom before feedback occurs. Global filter controls let you compensate for unexpected changes during a performance, while the display overlays filter responses on the incoming audio for easy monitoring. Designed for live sound engineers and performers who want a fast, one-person setup, X-FDBK suits anyone ringing out a PA or monitor system—from small venues to touring rigs—and works as a set-and-forget solution so you can focus on mixing rather than fighting squeals.
