Audio Modem

Audio Modem is a project which allows you to transfer data with sound. For instance, you need to send the string "Lorem ipsum dolor sit amet" from one device to another, after you calibrate these two devices, the sender converts this string to an audio data using amodem, than plays it. The reciever, by the way, records this voice. After it's finished, converts it to the original string, i.e decrypts it. This voice plays like one, maybe two, seconds. It means nothing for us but thanks to Audio Modem, we can transfer data with it.

I liked this repository because it is easy to install, calibrate and use it. Normally, someone who has not master audio technologies, like me, can not easily use this kind of a project. But thanks to the clear documentation and calibration module, I could use and test it without suffering any problem or technical detail. It is clearly described and coded.
