Does "tsw.load" work?

[DavidSabine]

Calling tsw.load as described here http://theresassoundworld.com/#load doesn't appear to work. The arguments are not parsed into arrays and objects which are compatible with the loadFile function.

For example, at line 589 ("number_of_files = Object.keys(files).length;"), the number_of_files will always equal 1 (if isArray(files) === true).

My REAL question: is tsw.load known to actually work currently? If so, I'll debug MY code -- if not, I'll debug tsw.load and submit a pull request.

Oh, let me look into it. Maybe the documentation isn't right. It currently works as in the tests:

https://github.com/stuartmemo/theresas-sound-world/blob/master/tests/tests.js

Starts line 352.

Saying that, would love your feedback on what syntax you prefer on loading files. I'm not 100% on what I've done.

Hi Stuart,

I did see your tests.js file -- it appears that you're testing the tsw.load function with only two arguments:

    describe('Load files', function () {
        var my_success;
        it('Load some mp3s', function (done) {
            tsw.load({
                files: {
                    sampleOne: 'samples/tsw1.mp3',
                    sampleTwo: 'samples/tsw2.mp3',
                    sampleThree: 'samples/tsw3.mp3',
                }
            }, function (success) {
                my_success = success;
                done();
            });
        });

Though the documentation http://theresassoundworld.com/#load allows for three args (the second being "path"):

tsw.load(
{
talking: 'talking-sample.mp3',
singing: 'my-lovely-singing.mp3'
},
{
path: '/path/to/files/'
},
function (response, status, xhr) {
if (status === 'success') {
// Files have loaded successfully
tsw.play(response.talking);
} else {
// There's been an error
console.log('We have a technical: ' + xhr.statusText);
}
}
);

Being able to define a path may be helpful, though not essential.

As far as syntax is concerned, I like what you've designed but I'm currently unclear how I can access the buffers after they're loaded -- that is, I'm not currently understanding how I can pass buffers to tsw.play() when I'm not inside the successCallback function. I think I should want access to an array of buffers that are available in the current audioContext -- maybe you've already implemented something this and I simply need to study more. I have something like this in mind (totally over-simplified, please forgive me):

// on DOMContentLoaded I'd like to load some buffers like:
var tsw.buffers = new Array();
tsw.buffers = tsw.load(anArrayOfUrls);

// at any time, I'd like to be able to add new buffers, maybe like:
tsw.buffers.push(tsw.load(aStringOfUrl));

// at any time, I'd like to be able to control all or individual buffers - somewhat like audio objects (gain, etc.), and somewhat like an array (push, splice, pop, etc), maybe like:
tsw.buffers.play(aTime,booleanLoop);
tsw.buffers.pan(0);
tsw.buffers[0].pan(-1);
tsw.buffers.gain(0.3);
tsw.buffers.remove(tsw.buffers[0]);

PLEASE don't heed my input too much though. I have more trust in your JavaScript knowledge than my own.

Ooh, that's a really good idea regarding the buffers. Currently you have to create a buffer using var my_buffer = tsw.buffer(); then assign the loaded buffer into my_buffer.

But like you say if buffers was a special array that converted a file into a playable buffer automatically then that'd be pretty nice!
