## What it is
Beep.js is a JavaScript toolkit for building browser-based synthesizers using the WebAudio API, with a batteries-included approach that lets you create a playable instrument in one line of code. It also supports MIDI controller keyboards via the Web MIDI API.

## Use cases
- build a browser-based synthesizer
- play music in the browser with WebAudio
- connect a MIDI keyboard to a web app
- create a software piano keyboard in JavaScript
- write and play musical scores in the browser
- teach music concepts interactively on the web

## When to choose
- you want a quick, batteries-included way to build a synth in the browser
- you need Web MIDI input support for a web instrument
- you're prototyping audio experiments or music lessons in JavaScript

## When to avoid
- you need a maintained library with recent updates and support
- you need advanced synthesis features beyond basic notes, voices, and scores
- you need non-browser (Node.js or mobile native) audio synthesis

## Facets
- artifact type: library
- maturity: abandoned
- function: audio-processing, sdk, developer-tools
- domain: web-development, media
- platform: browser
- tags: web-audio, web-midi, synthesizer, music, browser-based, audio, javascript, web-server
