ggwave is a compact C++ library for transmitting small amounts of digital information between nearby devices through sound. It uses a frequency-shift keying protocol that converts data into audible or ultrasonic audio tones. Reed-Solomon error correction improves reliability when recordings contain noise or imperfect frequency detection. The library generates and analyzes raw waveforms while allowing applications to choose their own audio capture and playback systems. It supports use cases such as device pairing, offline broadcasting, audio QR codes, authorization, and microcontroller communication. Bindings and examples are available for browsers, Python, Node.js, iOS, Android, Arduino, ESP32, and Raspberry Pi Pico. Command-line, graphical, WebAssembly, and file-based demonstrations are included.

A low-code dashboard makes monitoring intuitive for any admin, while scripting and custom sensors give experts full control.

You shouldn't have to choose between a monitoring tool that's easy to use and one that's powerful enough for a complex environment. PRTG's low-code interface lets any admin build dashboards, set alerts and monitor devices without scripting, while custom sensors and full API access are there when your team needs deeper control. One platform, no compromise. Download a free 30-day trial now.
