## What it is
A minimalistic single-header C library for decoding MP3 audio. It is small, fast with SSE/NEON SIMD support, and ISO-conformant with high accuracy.

## Use cases
- decode mp3 files in c or c++
- add mp3 playback to a game or embedded app
- decode mp3 without external dependencies
- convert mp3 to pcm samples
- embed a tiny audio decoder in a mobile app

## When to choose
- you need a dependency-free, single-file mp3 decoder
- you want small binary size and fast SIMD-accelerated decoding
- you need accurate, ISO-conformant mp3 decoding including free format

## When to avoid
- you need encoding, not just decoding
- you need other audio formats like ogg or flac
- you want a full audio playback engine with output device handling

## Facets
- artifact type: library
- maturity: stable
- function: audio-processing
- domain: media, cross-platform
- platform: cross-platform, c, cpp
- tags: mp3-decoder, single-header, header-only, embedded-audio, public-domain, audio
