## What it is
AmplitudeJS is a lightweight, dependency-free JavaScript library for building fully customizable HTML5 audio players on web pages. It lets designers control player appearance via CSS classes and attributes while providing playlists, shuffle/repeat, keyboard shortcuts, live streams, visualizers, and playback speed controls.

## Use cases
- build a custom-styled audio player for a website
- create a music playlist UI with next/previous and shuffle
- embed a podcast player with variable playback speed
- stream a live audio broadcast on a webpage
- add an audio visualizer to a web player
- replace the browser's default audio controls with branded design

## When to choose
- you want complete design control over an HTML5 audio player without fighting browser defaults
- you need playlists, shuffle, repeat, and metadata display out of the box
- you want a zero-dependency, CDN- or npm-installable audio library
- you're building podcast or music experiences with keyboard shortcuts and speed controls

## When to avoid
- you need video playback rather than audio
- you require advanced Web Audio API DSP or heavy audio processing
- you want a prebuilt drop-in player widget with no custom design work
- you need a maintained framework-integrated player for React/Vue with native components
