    I stumbled upon this:

    https://learn.adafruit.com/fft-fun-with-fourier-transforms/tone-input

    Which is completely awesome, as the Teensy does tone/sound matching.

    But, I want to do this with a B4A App. Basically, I play a specific sound and the App stores it. So then if the microphone hears that sound again (constantly monitoring) it does something in the app. Similar to a voice password unlock but without the voice.

    I am basically wanting to detect a certain sound and the App recognizes it and allows me to do something.

    any ideas? I was looking into the FFT library but it seems complicated.

    P.S. Something similar to whats out there, Whistle Finder app. You whistle and the phone alerts you. like if you lose it or something.
