Flanger Feedback Calculator
Calculate flanger resonance from feedback amount
About this calculator
The Flanger Feedback Calculator helps audio engineers and musicians determine the resonance characteristics of flanger effects based on feedback settings. Flangers create their signature swooshing sound by mixing delayed signals with the original audio, and the feedback parameter controls how much of the delayed signal is fed back into the effect. This calculator translates feedback amounts into resonance values, allowing you to predict and control the intensity of the flanger's peak frequencies and overall character.
How to use
Enter your desired feedback amount (typically as a percentage or decimal value) into the calculator. The tool will instantly compute the corresponding resonance level for your flanger effect. Use this information to dial in the perfect amount of feedback for your desired sound intensity and frequency emphasis.
Frequently asked questions
What is flanger feedback?
Flanger feedback is the amount of processed signal that's fed back into the effect input, creating resonance and emphasizing certain frequencies in the characteristic flanger sweep.
How does feedback affect flanger sound?
Higher feedback creates more pronounced resonance peaks, making the flanger effect more dramatic and intense, while lower feedback produces a subtler, gentler swooshing sound.
What's the ideal feedback range for flangers?
Most flangers work best with feedback between 10-70%. Very high feedback can cause instability or harsh resonances, while very low feedback may sound too subtle.
