sendspin/sendspin-cpp

# sendspin-cpp Standalone C++ library implementing the Sendspin synchronized audio streaming protocol. Builds on both ESP-IDF (ESP32) and host platforms (macOS/Linux). Designed to be consumed by ESPHome but has no ESPHome dependencies. [![A project from the Open Home Foundation](https://www.openhomefoundation.org/badges/ohf-project.png)](https://www.openhomefoundation.org/) ## Features - WebSocket-based audio streaming with server time synchronization - FLAC, Opus, and PCM audio decoding - Cross-platform: ESP-IDF (ESP32) and host (macOS/Linux) ## Documentation - **[Integration Guide](docs/integration-guide.md)** -- How to integrate sendspin-cpp into your application, including required callbacks, role composition, and platform setup - **[Internals](docs/internals.md)** -- Internal architecture, threading model, and inter-class communication ## Build ### Host (macOS/Linux) ```bash cmake -B build cmake --build build ``` Dependencies (fetched automatically via CMake FetchContent): ArduinoJson, micro-flac, micro-opus, IXWebSocket. ### ESP-IDF Used as an IDF component. Add to your project's `idf_component.yml`. ## Examples - **`examples/basic_client/`** -- Standalone host example with PortAudio audio output - **`examples/tui_client/`** -- Terminal UI host example with PortAudio audio output ## License Apache 2.0
