Miniaudio
miniaudio is a single-file C audio library used for audio playback, capture, and hardware interfacing across multiple operating systems. It functions as an audio hardware abstraction layer, an audio processing engine, an audio synthesis engine, and a codec and resampler.
The project implements a node-graph based system for routing digital audio signals, mixing, and 3D spatialization. It also includes a programmatic generator for noise patterns and basic waveforms used for sound creation and signal testing.
The library covers digital signal processing, including audio format conversion and sample-rate resampling. It provides capabilities for real-time audio capture from input devices and the encoding and decoding of common sound file formats.
Features
