history
Project history and usage
libsoundio is Andrew Kelley's small C library for cross-platform real-time audio input and output. 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.
