**NOTE**
This plugin works for **WebAudio** backend only for now.

### Usage

```js
import ExportAudioPlugin from "wavesurfer-export-audio-plugin";
const wavesurfer = WaveSurfer.create({
  container: document.getElementById("wavesurfer"),
  backend: "WebAudio", // Just WebAudio for now..
  ...
  plugins: [
      ...
      ExportAudioPlugin.create(),
      ...
  ],
});

document.getElementById('some-button').onclick = async () => {

    const lowpass = wavesurfer.backend.ac.createBiquadFilter({ type: 'lowpass' })
    wavesurfer.backend.setFilter(lowpass)

    const renderedBuffer = await wavesurfer.getRenderedAudioBuffer(); // Lowpass filter applied AudioBuffer
    
    wavesurfer.backend.disconnectFilters()
}

```

### Installation

```sh
$ npm i wavesurfer-export-audio-plugin
```

### Methods

- `getRenderedAudioBuffer` - Returns filters applied audio buffer. // Eq: Lowpass, Highpass
