Showing Progress precent when loading a file

[kyoukhana]

Is it possible to show percent loaded when loading a file to a grope like this

var AudioGroup = new Pizzicato.Group();
AudioGroup.addSound(new Pizzicato.Sound({source: 'file', options: { path: 'info.mp3', loop: true }}));

Then a play button will be enabled to play once the file is 100% loaded
