This is a plugin to create HTML5 <audio> elements in CKEditor.
Extract the contents of the zip in you plugins directory, so it ends up like
this
ckeditor\ ... images\ lang\ plugins\ ... audio\ plugin.js dialogs\ audio.js docs\ install.html styles.css images\ icon.png placeholder.png ... skins\ themes\
Now add the plugin in your config.js or custom js configuration
file:
config.extraPlugins='audio';
In your toolbar configuration, add a new 'Audio' item in the place where you want the button to show up.
You can use the config.filebrowserVideoBrowseUrl
entry to specify a url so the file browser shows just audio elements (as long as your configure properly your file browser).
Now empty the cache of your browser and reload the editor, the new button should show up and you can add <audio> elements into the content.
This plugin has been coded for CKEditor 4.4.5. It might be possible to backport it for older versions, but I don't think that it's worth the effort as sooner or later those installs will (or should) be upgraded to the current version.
Please, note that only newer browsers support the Audio element, in older ones a simple text linking to the source videos is provided, you might want to use some javascript or css to customize the final behavior of these elements.
