BadBIOS-style!

Download (requires Python)

Simple chat program using near ultrasonic frequencies. Works without WiFi or Bluetooth and won't show up in a pcap.

Note: If you can clearly hear the send script working then your speakers may not be high quality enough to produce sounds in the near ultrasonic range.

Usage
Run python send.py in one terminal window and python listen.py in another. Type your text into the send.py window and it should appear (after a delay) in the listen.py window.

Warning: May annoy some animals.

Installation
Quietnet is dependant on pyaudio and Numpy.
