# audio-speaker [![Build Status](https://travis-ci.org/audiojs/audio-speaker.svg?branch=master)](https://travis-ci.org/audiojs/audio-speaker) [![stable](https://img.shields.io/badge/stability-stable-brightgreen.svg)](http://github.com/badges/stability-badges) [![Greenkeeper badge](https://badges.greenkeeper.io/audiojs/audio-speaker.svg)](https://greenkeeper.io/)

Output audio stream to speaker in node or browser.

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

### Use as a stream

```js

var Speaker = require('audio-speaker/stream');

var Generator = require('audio-generator/stream');

Generator(function (time) {

	//panned unisson effect

	var τ = Math.PI * 2;

	return [Math.sin(τ * time * 441), Math.sin(τ * time * 439)];

})

.pipe(Speaker({

	//PCM input format defaults, optional.

	//channels: 2,

	//sampleRate: 44100,

	//byteOrder: 'LE',

	//bitDepth: 16,

	//signed: true,

	//float: false,

	//interleaved: true,

}));

```

### Use as a pull-stream

```js

const pull = require('pull-stream/pull');

const speaker = require('audio-speaker/pull');

const osc = require('audio-oscillator/pull');

pull(osc({frequency: 440}), speaker());

```

### Use directly

Speaker is [async-sink](https://github.com/audiojs/contributing/wiki/Streams-convention) with `fn(data, cb)` notation.

```js

const createSpeaker = require('audio-speaker');

const createGenerator = require('audio-generator');

let output = createSpeaker();

let generate = createGenerator(t => Math.sin(t * Math.PI * 2 * 440));

(function loop (err, buf) {

	let buffer = generate();

	output(buffer, loop);

})();

```
