SoundManager 2 makes it easier to play audio using JavaScript.
Using HTML5 and Flash, SoundManager 2 provides reliable cross-platform audio under a single JavaScript API. Get SoundManager 2
Speak and be heard
More sound, in more places
Despite being one of the senses, sound has largely been missing from the web due to inconsistent technology support. SoundManager 2 bridges this gap, making it easier to use audio across a growing variety of devices and platforms, both desktop and mobile.
Getting started is pretty easy, too.
A few live examples:
HTML5 + flash hybrid
Complexity, reduced
Supporting HTML5 audio can be tedious in modern browsers, let alone legacy ones. With real-world visitors using browsers ranging from mobile Safari to IE 6 across a wide range of devices, there can be many support cases to consider.
SoundManager 2 gives you a single, powerful API that supports both new and old, using HTML5 audio where supported and optional Flash-based fallback where needed. Ideally when using SoundManager 2, audio "just works."
- Desktop support: Windows, Mac OS, Linux
- Laptop/tablet support: Windows, Mac OS, Linux / Blackberry Playbook, Kindle Fire + other HTML5/Flash devices
- iPhone support: iOS 4.0 and newer
- iPad support: Version 1.0 (iOS 3.2) and newer
- Android OS supporting HTML5 and/or Flash (Version 2.3 or newer)
The ginsu knife: 11 KB
Big features, small footprint
But wait, there's more!
Performance is an important metric, too. SoundManager 2 packs a comprehensive, feature-rich API into as little as 11 KB over the wire when optimized; that's less than 8% of the original, uncompressed file size.
SM2 is self-contained, having no external dependencies, and is compatible with popular JavaScript frameworks.
The source code is BSD-licensed and is provided in fully-commented, non-debug and compiler-optimized "minified" versions appropriate for development and production use.
Basic
Playable links and playlists
These demos use unordered lists with MP3 links that play in-place; the UI is easily customized via CSS.
A richer playlist theme with optional time, seekable progress bar and a VU meter where supported:
Shiny
Data visualization features
The 360° player UI demo uses <canvas> and includes options for waveform and spectrum analysis data via Flash 9, adding beautiful visual feedback to the interface.

Experimental
Advanced prototypes
The Cassette Tape UI is a skinnable player based on the TDK MA-R90 cassette tape, a classic design from 1982.
Remember Type IV, Metal & Chromium/CrO2? Those were the days.
The "Wheels Of Steel" started as a simple CSS prototype, and evolved to replicate most of the UI and functionality of a traditional DJ set-up. Pitch bending, scratch and EQ effects are present where supported.

Getting started
Basic SoundManager 2 set-up
Including the script, configuring the url
and registering an onready()
callback:
<script src="soundmanager2.js"></script>
<script>
soundManager.setup({
// where to find flash audio SWFs, as needed
url: '/path/to/swf-files/',
onready: function() {
// SM2 is ready to play audio!
}
});
</script>
Upon execution of soundmanager2.js, SM2 will determine what Flash SWF to load (if any) based on the path defined in soundManager.url
.
After successful initialization, soundManager.onready()
will fire and sounds can be played.
By default, SM2 uses a Flash 8-based SWF build. Some additional features are available when using the Flash 9-based build.
For a live example, see the basic template demo.
Playing audio
Basic playback control
Once soundManager.onready()
has fired, sounds can be loaded and played.
Creating and playing a sound object
// create "mySound"...
var mySound = soundManager.createSound({
url: '/path/to/an.mp3'
});
// ...and play it
mySound.play();
Additional options and events can be specified when loading and playing sounds. For more examples of playback features, see API Demos.
Bonus
Additional demos
Examples using multi-track playback, progress and combinations of sound and animation:
"Audio sprites" (sound segments / samples) demo
With sound playback options like from
and to
, you can play portions of a larger, single-file "sprite" of many sounds.
For more live examples, see the API Demos.
