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!

Shared and exclusive mode on supported backends. Backend-specific configuration options. Device capability querying. Automatic data conversion between your application and the internal device. Sample format conversion with optional dithering. Channel conversion and channel mapping. Resampling with support for multiple algorithms. Simple linear resampling with anti-aliasing. Optional Speex resampling (must opt-in). Filters. Biquad Low-pass (first, second and high order) High-pass (first, second and high order) Second order band-pass Second order notch Second order peaking Second order low shelf Second order high shelf Waveform generation. Sine Square Triangle Sawtooth Noise generation. White Pink Brownian Decoding (requires external single-file libraries). WAV FLAC MP3 Vorbis via stb_vorbis (not built in - must be included separately). Encoding (requires external single-file libraries). WAV Lock free ring buffer (single producer, single consumer). | Your choice of either public domain or MIT No Attribution. Entirely contained within a single file for easy integration into your source tree. No external dependencies except for the C standard library and backend libraries.
