===

Simple Web Audio API based reverb effect.

Based on https://github.com/web-audio-components/simple-reverb by Nick Thompson.

Intended for use as a processor in [soundbank](https://github.com/mmckegg/soundbank), but it is compatible with any [Web Audio API](https://developer.mozilla.org/en-US/docs/Web_Audio_API) AudioNode set up.

## Install via [npm](https://npmjs.org/package/soundbank-reverb)

```bash

$ npm install soundbank-reverb

```

## API

```js

var Reverb = require('soundbank-reverb')

```

### `var reverb = Reverb(audioContext)`

Pass an instance of [AudioContext](https://developer.mozilla.org/en-US/docs/Web/API/AudioContext) to the constructor to create an AudioNode.

### `reverb.wet` [AudioParam](https://developer.mozilla.org/en-US/docs/Web/API/AudioParam)

### `reverb.dry` AudioParam

### `reverb.cutoff` AudioParam

Defaults to `20000`.

### `reverb.filterType` (get/set)

Defaults to `"lowpass"`.

Can be any of the filters types specified by [BiquadFilterNode](https://developer.mozilla.org/en-US/docs/Web/API/BiquadFilterNode.type)

### `reverb.time` (get/set)

Impulse time in seconds. Defaults to `3`.

### `reverb.decay` (get/set)

### `reverb.reverse` (get/set)

`true` or `false`. Defaults to `false`.

## Example

```js

var Reverb = require('soundbank-reverb')

var audioContext = new AudioContext()

var reverb = Reverb(audioContext)

reverb.connect(audioContext.destination)

reverb.time = 1 //seconds

reverb.wet.value = 0.8

reverb.dry.value = 1

reverb.filterType = 'lowpass'

reverb.cutoff.value = 4000 //Hz

setInterval(function(){

  var source = audioContext.createOscillator()

  source.type = 'sawtooth'

  source.connect(reverb)

  source.start()

  source.stop(audioContext.currentTime + 0.5)

}, 2000)

```
