Audio Feedback Trainer

Welcome to the home of the Audio Feedback Trainer App. 

I developed this simple and effective app to help aspiring and seasoned audio engineers identify and eliminate the number one enemy of live audio: Feedback!

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.


Double-tap on any slider or press STOP to kill feedback. 


Press START for random frequencies.


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


We got rid of the lowest and highest frequencies that a standard sound system won’t reproduce, making room for the sliders. 

You can get the AFT app in the App Store and Google Play.


I'm an entrepreneur, music producer, and audio engineer.

I also love video production.  I'm pretty good with mirrorless cameras and gimbals.

I produce, from concept to master, all my band's youtube videos.
