## What it is
Quietnet is a simple Python chat program that transmits text between machines using near-ultrasonic sound frequencies, requiring no WiFi or Bluetooth. It is explicitly a toy/demo project built on pyaudio and NumPy, last released in 2017.

## Use cases
- send text between computers using sound instead of wifi or bluetooth
- communicate without network traffic showing up in a pcap
- experiment with ultrasonic data transmission in python
- demo of data-over-sound communication
- chat between two terminals on the same machine via audio

## When to choose
- you want a minimal, hackable python demo of ultrasonic data transmission
- you need communication that leaves no network traces and uses no radio hardware
- you're learning how audio-based signaling works

## When to avoid
- you need a robust, production-grade data-over-sound solution (use quiet-js, minimodem, or gnuradio)
- your speakers or microphones can't handle near-ultrasonic frequencies
- you need fast or reliable message delivery - transmission has noticeable delays
- you need an actively maintained project
