Feedback is the Number One Enemy of Live Sound.
Don't get fired! Become a ninja feedback killer with the AFT App.
Learn to identify frequencies working with the right tool for the job, the 31-band graphic equalizer.
You will create muscle (Finger) memory within the graphic EQ, so it becomes second nature.
For a better experience, use headphones or speakers at LOW VOLUMES.

The AFT App is incredibly easy to use:

Slide Up to learn different frequencies (Without pressing START).

Press Stop or Double-tap on any slider to stop feedback.

For Random Frequencies Press START.

Slide Down to kill feedback (as you would in a live situation).

We got rid of the lowest and highest frequencies (20Hz, 25Hz, 16k, and 20k) that a standard sound system can't reproduce, making room for the sliders, so you are working with a 27-band EQ.
