Html5 Introduces a new Technology for soundeffects when rollover the link or clicks.HTML5’s script uses new audio element to allow you to easily add sound effects to any action on the page, such as when the user clicks or rolls over a link. The script works in all browsers that support HTML5, which currently are IE9+, FF3.5+, Chrome/Safari 3+, and Opera 10.5+. And since it uses HTML5 to play the audio, the entire process is completely native and highly optimized in browsers that support it. Different browsers support different file formats, so it’s important to specify multiple versions of the same audio file to cover your bases. For example, Firefox/Chrome/Opera supports the .ogg format while IE9+/Safari supports the mp3 format instead.
