DISCLAIMER.

• I did not write this code. The original Author and Creator Dan Rouse has not been active updating this package. I fixed some issues I needed for my personal project and uploaded here to NPM because his package was broken and not usable through npm install!

Audio Recorder

A React Component using the Web Audio API to record, save, and play audio.

Demo & Examples

Live demo: danrouse.github.io/react-audio-recorder

Installation

The easiest way to use react-audio-recorder is to install it from NPM and include it in your own React build process (using Webpack, Browserify, etc).

You can also use the standalone build by including dist/AudioRecorder.min.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.

npm install react-audio-recorder-wavdownloader --save

Usage

The <AudioRecorder> component can be instantiated with no properties to act as a simple client-side recorder/downloader. onChange is called when a recording is finished, with the audio data passed as a blob.

import AudioRecorder from 'react-audio-recorder-wavdownloader';

<AudioRecorder />

For more detailed usage examples, see the live demo.

Notes

This component is intended for use with short sounds only, such as speech samples and sound effects. The WAV encoder is not offloaded to a service worker, to make this component more portable. It is not space efficient either, recording at 1411kbps (16 bit stereo), so long recordings will drain the system of memory.

Compatibility

Because of its usage of the Web Audio API, react-audio-recorder is not compatible with any version of Internet Explorer (Edge is compatible).

Development

To use the typescript watcher, run npm run dev.
