# Audio Recorder

An alternative to the `MediaRecorder` API for capturing audio. It wraps the well supported (but deprecated) [`ScriptProcessorNode`](https://developer.mozilla.org/en-US/docs/Web/API/ScriptProcessorNode) as well as the newer (but poorly supported) [`AudioWorkletNode`](https://developer.mozilla.org/en-US/docs/Web/API/AudioWorkletNode)/[`AudioWorkletProcessor`](https://developer.mozilla.org/en-US/docs/Web/API/AudioWorkletProcessor).

## Getting Started

The library consists of 3 files:

- `audio-recorder.js`: the main entry point

- `audio-recorder-worklet.js`: used in the most recent browsers

- `audio-recorder-worker.js`: used browsers that don't support Audio Worklets

The worklet and worker files need to be referencable via a URI.

### Basic Usage

Import the library, then instantiate an `AudioRecorder`, passing in the [streaming audio source node](https://developer.mozilla.org/en-US/docs/Web/API/MediaStreamAudioSourceNode) and the worker URIs:

```js

import AudioRecorder from './path/to/audio-recorder'

const audioRecorder = new AudioRecorder({

  source: source,

  workletUri: 'path/to/audio-recorder-worklet.js',

  workerUri: 'path/to/audio-recorder-worker.js'

})

```

Start the recording and capture the data when available:

```js

audioRecorder.on('dataavailable', function () {

  const blob = new Blob([event.data.buffer], { type: 'audio/wav' })

})

audioRecorder.start()

```

Stop the recording when done:

```js

audioRecorder.stop()

```
