The ID3Info class contains properties that reflect ID3 metadata. You can get additional metadata for MP3 files by accessing the id3 property of the Sound class; for example, mySound.id3.TIME. For more information, see the entry for Sound.id3 and the ID3 tag definitions at


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.


The SoundChannel class controls a sound in an application. Every sound is assigned to a sound channel, and the application can have multiple sound channels that are mixed together. The SoundChannel class contains a stop() method, properties for monitoring the amplitude (volume) of the channel, and a property for assigning a SoundTransform object to the channel.


The SoundLoaderContext class provides security checks for files that load sound. SoundLoaderContext objects are passed as an argument to the constructor and the load() method of the Sound class.


The SoundMixer class contains static properties and methods for global sound control in the application. The SoundMixer class controls embedded and streaming sounds in the application. it does not control dynamically created sounds (that is, sounds generated in response to a Sound object dispatching a sampleData event).


The SoundTransform class contains properties for volume and panning.


The Video class displays live or recorded video in an application without embedding the video in your SWF file. This class creates a Video object that plays either of the following kinds of video: recorded video files stored on a server or locally, or live video captured by the user. A Video object is a display object on the application's display list and represents the visual space in which the video runs in a user interface. When used with Flash Media Server, the Video object allows you to send live video captured by a user to the server and then broadcast it from the server to other users. Using these features, you can develop media applications such as a simple video player, a video player with multipoint publishing from one server to another, or a video sharing application for a user community.
