I want to implements this: http://rnd.azoft.com/mobile-app-transering-data-using-ultrasound/ in an Android App.
I implemented the design of the App in Android Studio and the last thing that I need to implements its the "Transfer Button" in other words - I need to convert a byte array like [1,0,0,1,0,1,0] to inaudible sound waves and receive in another mobile the sound and convert the sound to byte array [1,0,0,1,0,1,0] back.
where to start? thank a lot.
