Speaker is async-sink 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);
})();
