npm package size minified + gzipped size

Demo

Check it out in action with the Online Demo (see also the Real-World Usage section :D)!

Running Demo Locally

The demo can also be run locally. Clone this repository, and then run the following from the root of this repo:

npm install
npm run demo

Quick example:

var soundbox = new SoundBox();
soundbox.load("beep-a", "beep-a.wav")
    .then(
        () => console.log("Loaded beep a!"),
        () => console.error("Failed to load keep a :-(")
    );
soundbox.load("beep-b", "beep-b.wav");
soundbox.load("beep-c", "beep-c.wav");
soundbox.load("victory", "victory.mp3");

soundbox.play("beep-a")
    .then(() => soundbox.play("beep-b"))
    .then(() => soundbox.play("beep-c"))
    .then(() => soundbox.play("victory"));
    
// The 3rd parameter is the volume: The callback can be omitted to enable promise mode
soundbox.play("beep", null, 0.8)
    .then(() => soundbox.play("victory"))

(Full documentation below)

Download

The recommended way to obtain soundbox is via npm here: sound-box - To install it simply type npm install sound-box. Then you can include any of the 4 files described below from the ./node_modules/sound-box/ directory.

If npm isn’t for you, then the latest master should be perfectly stable. If you want something that you know will work, try the latest release.

The following files are available via all release methods:

Usage

Create a new instance:

var soundbox = new SoundBox();

Load a sound

Sound loading is done as follows. If a callback is not specified, promise mode is activated.

// Promise mode
soundbox.load("alias", "path/to/filename").then(
    () => console.log("Loaded beep!"),
    () => console.error("Failed to load beep :-(")
);
soundbox.load("victory", "./sounds/yay.wav").then( /* .... */);
// Callback mode
soundbox.load("alias", "path/to/filename", function() {
    console.log("Loaded beep!");
});

Play a sound

Similarly, playing a sound takes 2 forms: callback and promise.

// Promise mode
soundbox.play("beep-a")
    .then(() => soundbox.play("beep-b")) /* The .then() is optional of course */
    .then(() => soundbox.play("beep-c"))
    .then(() => soundbox.play("victory"));
// Callback mode
soundbox.play("beep", function() {
	// Do stuff
});

Specify the volume

The volume can be specified when playing a sound, too. The volume should be a floating-point number between 0 (silent) and 1 (full volume, default).

Here’s how:

// Promise mode
soundbox.play("beep-a", null, 0.8)
    .then(() => /* .... */);
// Callback mode
soundbox.play("beep", function() {
	// Do stuff
}, 0.5);

Specify the default volume

If you’d like to change the default volume that sounds are played at, do this:

soundbox.default_volume = 0.45; // Sets the default volume to 45%

Looping again and again

As of v0.3.7, looping support has been added. Use it like this:

// Promise mode
soundbox.play("rocket", null, 0.8, true)
    .then(() => /* .... */);
// Callback mode
soundbox.play("rocket", function() {
	// Do stuff
}, null, true); // A null volume = use the default volume. Supported in both modes of operation

Stop all sounds

You can stop all currently playing sounds like this:

soundbox.stop_all();

Unload a sound

If you want to, you can unload a sound:

soundbox.remove("sound_alias");
soundbox.remove("oops");

Get the current version

Get the current version of SoundBox:

console.log(`Soundbox is at ${SoundBox.version}`);
