Sonar

Sonar is a Rust project exploring data transmission using audio signals. It aims to enable communication across air-gapped systems or in environments where traditional networking is not an option, using only standard microphones and speakers.

We're building a modular system with different sound encoding techniques (like FSK and BPSK) and a layered approach to structure the data for reliable transfer. The project includes a command-line tool to easily send and listen for these audio-based messages.

This project is currently in an active prototyping and development phase. Many features are experimental and APIs are subject to change.

Installation

cargo install sonar
