plucky

compose musical callbacks into plucky arrangements

example

var baudio = require('baudio');
var b = baudio({ rate : 44100 });
var tau = 2 * Math.PI;
var player = require('plucky');

var music = [
    function (t, clip) {
        if (t > 1 / 4) clip.end();
        return Math.sin(tau * 200 * t);
    },
    function (t, clip) {
        if (t > 1 / 4) clip.end();
        return Math.sin(tau * t * 200 * Math.pow(2, 1/3));
    },
    function (t, clip) {
        if (t > 1 / 2) clip.go(0);
        return Math.sin(tau * t * 100)
            + Math.sin(tau * t * 105) / 8
        ;
    }
];
b.push(player(music));
b.play();

methods

var plucky = require('plucky')

var f = plucky(music, end)

Return a baudio-compatible function given an array of music functions.

Each function in the array music will be called fn(t, clip) with the relative time in seconds since it was started t and a clip object described below. Musical functions should return a floating point value between -1 and 1, inclusive.

If provided, end() fires when there's no more music to play.
