+/**
+	The Sound class lets you work with sound in an application. The Sound class
+	lets you create a Sound object, load and play an external MP3 file into
+	that object, close the sound stream, and access data about the sound, such
+	as information about the number of bytes in the stream and ID3 metadata.
+	More detailed control of the sound is performed through the sound source
+	 -  the SoundChannel or Microphone object for the sound  -  and through the
+	properties in the SoundTransform class that control the output of the sound
+	to the computer's speakers.
+
+	In Flash Player 10 and later and AIR 1.5 and later, you can also use
+	this class to work with sound that is generated dynamically. In this case,
+	the Sound object uses the function you assign to a `sampleData`
+	event handler to poll for sound data. The sound is played as it is
+	retrieved from a ByteArray object that you populate with sound data. You
+	can use `Sound.extract()` to extract sound data from a Sound
+	object, after which you can manipulate it before writing it back to the
+	stream for playback.
+
+	To control sounds that are embedded in a SWF file, use the properties in
+	the SoundMixer class.
+
+	**Note**: The ActionScript 3.0 Sound API differs from ActionScript
+	2.0. In ActionScript 3.0, you cannot take sound objects and arrange them in
+	a hierarchy to control their properties.
+
+	When you use this class, consider the following security model:
+
+
+	* Loading and playing a sound is not allowed if the calling file is in
+	a network sandbox and the sound file to be loaded is local.
+	* By default, loading and playing a sound is not allowed if the calling
+	file is local and tries to load and play a remote sound. A user must grant
+	explicit permission to allow this type of access.
+	* Certain operations dealing with sound are restricted. The data in a
+	loaded sound cannot be accessed by a file in a different domain unless you
+	implement a cross-domain policy file. Sound-related APIs that fall under
+	this restriction are `Sound.id3`,
+	`SoundMixer.computeSpectrum()`,
+	`SoundMixer.bufferTime`, and the `SoundTransform`
+	class.
+
+
+	However, in Adobe AIR, content in the `application` security
+	sandbox(content installed with the AIR application) are not restricted by
+	these security limitations.
+
+	For more information related to security, see the Flash Player Developer
+	Center Topic: [Security](http://www.adobe.com/go/devnet_security_en).
+
+	@event complete   Dispatched when data has loaded successfully.
+	@event id3        Dispatched by a Sound object when ID3 data is available
+					  for an MP3 sound.

+	@event progress   Dispatched when data is received as a load operation

+
+		When using this property, consider the Flash Player security model:
+
+		* The `id3` property of a Sound object is always permitted for SWF
+		files that are in the same security sandbox as the sound file. For
+		files in other sandboxes, there are security checks.
+		* When you load the sound, using the `load()` method of the Sound
+		class, you can specify a `context` parameter, which is a
+		SoundLoaderContext object. If you set the `checkPolicyFile` property
+		of the SoundLoaderContext object to `true`, Flash Player checks for a
+		URL policy file on the server from which the sound is loaded. If a
+		policy file exists and permits access from the domain of the loading
+		SWF file, then the file is allowed to access the `id3` property of the
+		Sound object; otherwise it is not.
+
+		However, in Adobe AIR, content in the `application` security sandbox
+		(content installed with the AIR application) are not restricted by
+		these security limitations.

+		* If the POST operation is cross-domain(the POST target is not on the
