## What it is
SoundManager 2 is a JavaScript sound API that wraps HTML5 Audio and legacy Flash to provide reliable cross-browser audio playback control (MP3, MP4/AAC, OGG, RTMP) in as little as 12 KB. It exposes a single API for loading, playing, pausing, seeking, and volume control with rich event callbacks.

## Use cases
- play mp3 audio from javascript in the browser
- add a play/pause button to audio links on a website
- build a custom web audio player UI
- support audio playback across desktop and mobile browsers
- stream audio with legacy flash/RTMP fallback
- read ID3 tags from mp3 files in the browser

## When to choose
- you need a small, battle-tested cross-browser audio API with legacy browser/Flash fallback
- you want fine-grained playback events like whileloading, whileplaying, and onfinish
- you must support very old browsers or Flash-based RTMP streaming

## When to avoid
- you only target modern browsers and can use the native HTML5 Audio or Web Audio API directly
- your project requires active maintenance or modern tooling, as the project is largely in maintenance mode with last release in 2021
- you need video playback or advanced Web Audio features like real-time synthesis

## Facets
- artifact type: library
- maturity: maintenance
- function: audio-processing, developer-tools
- domain: web-development, frontend, media
- platform: browser, cross-platform
- tags: audio-api, html5-audio, flash-fallback, mp3, javascript, sound-playback, legacy-flash-support, audio
