AudioElement is a media element specifically created for audio playback. It supports both streaming and progressive formats.

AudioElement can load and present any MP3 or AAC file. It supports MP3 files over HTTP, as well as audio-only streams from Flash Media Server.

The basic steps for creating and using an AudioElement are:

Create a new URLResource pointing to the URL of the audio stream or file containing the sound to be loaded.
Create the new AudioElement, passing the URLResource as a parameter.
Create a new MediaPlayer.
Assign the AudioElement to the MediaPlayer's media property.
Control the media using the MediaPlayer's methods, properties, and events.
When done with the AudioElement, set the MediaPlayer's media property to null. This will unload the AudioElement.

Defines the duration that the element's TimeTrait will expose until the element's content is loaded. Setting this property to a positive value results in the element becoming temporal. Any other value will remove the element's TimeTrait, unless the loaded content is exposing a duration.

Constructor.

Parametrar

	`resource:URLResource` (default = `null`) — URLResource that points to the audio source that the AudioElement will use.

	`loader:LoaderBase` (default = `null`) — Loader used to load the sound. This must be either a NetLoader (for streaming audio) or a SoundLoader (for progressive audio). If null, the appropriate Loader will be created based on the type of the resource.

Utlöser

ArgumentError — If loader is neither a NetLoader nor a SoundLoader.
