Media

The Media object provides the ability to record and play back audio files on a device.

var media = new Media(src, mediaSuccess, [mediaError], [mediaStatus]);

NOTE: The current implementation does not adhere to a W3C specification for media capture, and is provided for convenience only. A future implementation will adhere to the latest W3C specification and may deprecate the current APIs.
