Feedback Trainer

Start with your device volume low. Each training sound fades in smoothly so you have time to adjust safely.

Training flow

The ringing tone plays without pink noise. The level meter and live guidance help you learn how far to lower the fader.

What this trainer does

This tool helps live sound engineers, rehearsal room users, and musicians recognize feedback frequencies faster. The three levels change the amount of pink noise, visual guidance, and feedback-level variation. You can practice finding the problem band and cutting only what is needed.

How to use it

Start at a low volume. You can use Listen Mode to hear each frequency band before training. Training questions use practical feedback bands from 63 Hz to 8 kHz. During a training session, move the most likely fader down and use Lock In when the feedback feels stable. The final report shows frequency accuracy, response time, cut control, and unnecessary moves. Free Practice lets you keep going until you choose to end the session.
