About:
Libsoundio is a lightweight, cross-platform audio library designed for low-latency input and output. It provides a robust abstraction layer over platform-specific backends like ALSA, PulseAudio, CoreAudio, and WASAPI. Its main value proposition is offering high-performance audio handling without the heavy dependencies found in larger frameworks.

Key Features:

Cross-platform backend abstraction (ALSA, PulseAudio, CoreAudio, WASAPI)
Low-latency and high-performance audio processing
C API with C++ wrapper for flexible integration
Support for raw audio data and device discovery

Use Cases:

Developing low-latency audio applications
Building audio engines for games or DAWs
Creating cross-platform audio utilities

Alternatives:

PortAudio – PortAudio is a widely used alternative, while Libsoundio offers a more modern API and specific focus on low-latency raw audio streams.
SDL2 – SDL2 is a broader multimedia library; Libsoundio is a dedicated audio I/O layer with a smaller footprint.
