There are some other NPM packages regarding RecordRTC:

* [https://www.npmjs.org/search?q=RecordRTC](https://www.npmjs.org/search?q=RecordRTC)

Here is how to use `require`:

```javascript
var RecordRTC = require('recordrtc');
var Whammy = RecordRTC.Whammy;
var WhammyRecorder = RecordRTC.WhammyRecorder;
var StereoAudioRecorder = RecordRTC.StereoAudioRecorder;
// and so on

var video = new Whammy.Video(100);
var recorder = new StereoAudioRecorder(stream, options);
```

## How to capture stream?
