It sits below applications that need a direct, backend-aware audio API without committing to JACK, PulseAudio, ALSA, CoreAudio, or WASAPI separately. ### Project history The GitHub repository describes libsoundio as a C library suitable for real-time software such as digital audio workstations and for consumer software such as music players. Release-tag commit metadata shows version 1.0.0 on September 3, 2015 and version 2.0.0 on February 20, 2019. ### Adoption history The project attracted packaging across Homebrew, Debian, Fedora, MacPorts, Nix, Alpine, and other Unix-like distributions because it offered a thin, MIT-licensed C abstraction over the main desktop audio backends. ### How it is used Users link against libsoundio for real-time playback, capture, device enumeration, backend selection, channel layouts, and device-change events. The package also includes examples and utilities such as sio_list_devices, sio_sine, sio_microphone, and sio_record. ### Why package nerds care libsoundio is a package-nerd library because it exposes the messy cross-platform audio boundary as one small C dependency. It is less historically central than libsndfile, but it is useful when applications want low-level audio I/O without bundling backend-specific code. ### Timeline - 2015-09-03: Version 1.0.0 release-tag commit. - 2019-02-20: Version 2.0.0 release-tag commit. - 2019: The 2.0.0 documentation set became the referenced packaged API documentation surface. ### Related projects - JACK, PulseAudio, ALSA, CoreAudio, and WASAPI are the backend APIs that libsoundio abstracts. - Language bindings and wrapper packages use libsoundio as the native layer for higher-level ecosystems. ### Sources - - - - - - ## Security Notes broad file, network, media, or database tool signal. -
