Zynga's Jukebox (v1.0)
The Jukebox is a component for playing sounds and music with the usage of sprites with a special focus on performance and cross-device deployment. It is known to run even on Android 1.6+ devices and needs very few resources compared to other solutions on the web.
- Targets low-end devices and mobile platforms
- HTML5 Audio
- Flash Audio as fallback (support for Android 1.6)
- Sound-Spritemap Entries for easier playback
- Multiple Jukeboxes for parallel playback
Jukebox Manager adds the following features:
- Codec Detection
- Feature Detection
- Automatic Work Delegation for busy Jukeboxes
- Automatic Stream Correction (useful for slow implementations)
- Automatic Looping for Sound-Spritemap entries
- Playback of Background Music
Using Jukebox without Jukebox Manager:
It is not recommended to use Jukebox without the Jukebox Manager, but it's still possible. The Jukebox Manager offers Codec and Feature detection - to determine which kind of audio codecs will playback properly in your environment. If you want to still use Jukebox without Jukebox Manager, you will have to set resources to an Array containing only one resource.
- Dynamic balancing of free clones at runtime
There's a huge documentation of Jukebox available at github pages. You are invited to read it, there are also many try-it-yourself demos.
The documentation is also attached in the /doc folder if you clone the git repository.
Known Issues (iOS)
iOS has a huge delay when using an encoded format for playback. That's because of their iTunes-using implementation. You can fix these delays using an AIFF container with IMA4 encoding. These are called Core Audio Files then.
Further there is only the capability of playing back one sound in parallel on iOS.
