    Use as a stream

    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

    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 with fn(data, cb) notation.

    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);
    })();
