Minmalist C++20 audio library
- Audio source 3D positioning
- Audio clip playback (direct)
- Streaming playback with accurate and near-instant seeking
- RAII types
- Exception-less implementation
- Error callback (optional)
- Lightweight and more optimized rendition of capo
- Zero public dependencies (except standard library)
App: player (capo-lite example)
Note: GUI powered by gvdi
- C++20 compiler (and standard library)
- CMake 3.18+
- WAV
- FLAC
- MP3

stream_source.play(); // start playback
while (stream_source.state() == capo::State::ePlaying) {
std::this_thread::yield(); // wait until playback complete
}
}sound and music demonstrate basic sound and music usage, player demonstrates a scrappy Dear ImGui based music player.
