SoundManager2提供一套在javascript中用来控制声音的API。该Javascript library封装和扩展了Flash的声音功能，为Javascript提供跨平台的音频控制功能。

此次，SoundManager2添加了对 HTML5 Audio()的支持：

• 100% Flash-free MP3 + MP4/AAC where supported, Apple iPad™-compatible
• Fallback to Flash for MP3/MP4 support, as needed
• SM2 API is unchanged, transparent; HTML5/flash switching handled internally
• HTML5 API support approximates Flash 8 API features, minus ID3, plus buffering
• Some other formats (WAV/OGG) supported via HTML5, depending on browser
• See soundManager.useHTML5Audio for implementation details.
• Your browser's HTML5 vs. Flash support (best guess):mp3 mp4 ogg wav
