Record a user's voice and display as an oscillation (or frequency bars).
Plug-n-play component for React apps.
Audio is saved as WebM audio file format. Works via the HTML5 MediaRecorder API (currently only available in Chrome & Firefox).
PLEASE NOTE: The WebM audio format is not supported in Safari browsers (including Safari on iOS). You need to save an audio recording as an MP3 or WAV file in order to get full cross-browser and cross-device support.
You can do that with the premium enhancement of this component called React-Mic-Gold.
Companies that develop speech-recognition apps, voice-activated software, apps that require audio recording features, or language-learning products all use React-Mic-Gold.
npm install --save react-mic
yarn add react-mic
Check out the simple React-Mic demo.
- Record audio from microphone
- Display sound wave as voice is being recorded
- Save audio as BLOB

React-Mic-Gold lets you record audio as either MP3 or WAV files. The MP3 audio file format is super compressed which will result in small file sizes, and is widely supported across all devices. The WAV audio file format is uncompressed and is used when you need professional quality audio; however, the file size is significantly larger.
Check out the simple demo of React-Mic-Gold in action here.
Also, check out React-Mic-Gold integrated into an actual app here.
In React-Mic-Gold, encoding of recorded audio into MP3 format happens in the browser, via a combination of advanced Web technologies (Web Workers and Web Assembly).
You won't have to continuously stream audio data to your back-end server or API endpoint to convert captured audio into an MP3 file. Althought you can if you want to.
React-Mic-Gold also comes with an optional pause feature and additional premium enhancements.
