## What it is
Recorder.js is a JavaScript library that records and exports the output of Web Audio API nodes, capturing audio into WAV blobs. It works via a Web Worker to encode recorded stereo buffers for playback or download.

## Use cases
- record microphone audio in the browser
- capture output of a Web Audio API node
- export recordings as WAV files
- record voice memos in a web app
- capture and download audio from a synthesizer or effect chain

## When to choose
- you need simple WAV recording from Web Audio nodes in a legacy browser environment
- you want a minimal, dependency-free audio capture library to fork or adapt

## When to avoid
- you need an actively maintained library with bug fixes and modern browser support
- you need compressed formats like MP3 or OGG out of the box
- you are starting a new project - consider MediaRecorder API or maintained forks
