## What it is
A JavaScript HTML5 audio recording library for browsers and hybrid apps, supporting mp3, wav, pcm, ogg, amr, webm, and g711 formats with real-time processing, transcoding, and streaming. It includes plugins for audio visualization, speed/pitch adjustment, ASR speech recognition, and real-time voice chat over WebSocket/WebRTC, with support for WeChat mini-programs and uni-app via RecordApp.

## Use cases
- record audio from microphone in a web page
- record voice as mp3 or wav in the browser
- stream recorded audio in real time to a server
- add speech recognition (ASR) to a web app
- build an H5 voice call / walkie-talkie chat feature
- record audio inside WeChat mini-program or uni-app
- convert PCM buffers to mp3 or other audio formats
- visualize microphone audio in the browser

## When to choose
- you need browser-based microphone recording with broad mobile and PC browser support
- you need multiple output formats or real-time encoding and streaming
- you're building hybrid apps, WeChat mini-programs, or uni-app recording features
- you need real-time audio processing, visualization, or ASR integration in JavaScript

## When to avoid
- you need multichannel/stereo recording (mono only)
- you need native app recording outside JavaScript environments
- you need server-side audio encoding as the primary use case
- you must support very old browsers or legacy iOS (11.0-14.2) non-Safari browsers
