A single file audio playback and capture library.
Download miniaudio.h
miniaudio is a single file audio playback and capture library written in C. Written from scratch, it has no external dependencies with the exception of the C standard library and necessary platform-specific backends.

Works Out of the Box
Just add to your source tree and go. There's no need to install any dependencies or development packages, nor are there any build systems to waste time on.

Cross Platform
miniaudio works on all the major desktop and mobile platforms, including Windows, macOS, Linux, BSD, iOS, Android and Web (via Emscripten).

Simple
miniaudio has a simple, yet flexible low-level API that gets out of your way. Just initialize a device and start sending audio data via a callback.

And best of all, it's free and open-source!
You can find miniaudio on GitHub
