## What it is
Tone.js is a Web Audio framework for creating interactive music in the browser. It provides DAW-like features such as a global transport for scheduling, prebuilt synths, effects, and building blocks for custom audio applications.

## Use cases
- play synthesized notes in the browser
- build an interactive music web app
- schedule audio events synced to a tempo
- create custom synthesizers and effects with Web Audio
- build a browser-based step sequencer or drum machine
- add sound effects and generative music to a game or website

## When to choose
- you want a high-level, musician-friendly API over the raw Web Audio API
- you need transport-based scheduling and synchronization of musical events
- you want prebuilt synths, effects, and samples out of the box

## When to avoid
- you need offline audio rendering or non-browser audio processing
- you only need simple audio playback without synthesis or scheduling
- you are building a native mobile or desktop audio app outside the browser

## Facets
- artifact type: framework
- maturity: stable
- function: audio-processing, scheduling, animation
- domain: web-development, media, frontend
- platform: browser
- tags: web-audio, synthesizer, music, daw, synthesis, interactive-music, effects, transport, audio, javascript, nodejs, web
