# app-audio [![unstable](http://badges.github.io/stability-badges/dist/unstable.svg)](http://github.com/badges/stability-badges)

Get audio for your application, demo or tests.

It will create a component with every possible audio source for Web Audio API - an audio file, url, soundcloud, microphone or primitive signal. Also it tackles play/stop/reset controls, drag-n-drop, recent tracks, soundcloud tracklists, queuing multiple tracks, saving to session storage, progress bar, looping etc.

[![app-audio](https://raw.githubusercontent.com/audio-lab/app-audio/gh-pages/preview.png "app-audio")](http://audio-lab.github.io/app-audio/)

## Usage

[![npm install app-audio](https://nodei.co/npm/app-audio.png?mini=true)](https://npmjs.org/package/app-audio/)

```js
const createAudio = require('app-audio');

let audioSrc = createAudio({
source: './my-audio.mp3'
}).on('ready', (node, url) => {
node.connect(myAnalyzer);
});
```

## API

**`const createAudio = require('app-audio');`**

Get app-audio constructor. It can also serve as a class.

**`let appAudio = createAudio(options);`**

Create app-audio instance based off options:

```js
//initial source
source: null,

//container to place UI
container: document.body,

//audio context to use
context: require('audio-context'),

//Enable file select
file: true,

//Enable url input
url: true,

//Enable soundcloud input
soundcloud: true,

//Enable primitive signal input
signal: true,

//Enable mic input
mic: true,

//Show play/payse buttons
play: true,

//Start playing whenever source is selected
autoplay: true,

//Repeat track list after end
loop: true,

//Show progress indicator at the top of container
progress: true,

//Save/load tracks to sessionStorage
save: true,

//Show list of recent tracks
recent: true,

//Enable drag and drop files
dragAndDrop: true,

//Default color
color: 'black'
```

**`appAudio.on(event, callback);`**

Bind event callback. Available events:

```js
//called whenever new source is set and loaded, like mic, file, signal etc.
//source audioNode is passed as a first argument, so do connection routine here
appAudio.on('load', (audioNode, sourceUrl) => {
audioNode.connect(myAnalyzer);
});

//whenever play is pressed or called
appAudio.on('play', (audioNode) => {});

//whenever pause is pressed or called
appAudio.on('pause', (audioNode) => {});

//whenever reset is called
appAudio.on('reset', () => {});
```

**`appAudio.set(source);`**

Set source to play. Source can be whether `File`, `FileList`, URL, soundcloud URL, list of URLs, `MediaStream` etc.

**`appAudio.play();`**

Play selected source. Other playback methods:

```js
//pause current source, for mic - mute output
appAudio.pause();

//reset current source, stop playback
appAudio.reset();

//play next track, if there are multiple tracks
appAudio.playNext();
```

**`appAudio.show();`**

Open menu. To hide menu, call `appAudio.hide()`

**`appAudio.update(options?);`**

Update view or options, if required. Possible options are all the same as in the constructor.
