For example, suppose you're creating an online game that uses different sounds depending
on what level the user has reached in the game. The following code loads an MP3 file
(blastoff.mp3) into a Sound object named

var gameSound:Sound = new Sound();
gameSound.onLoad = function (loadedOK) {

Reading ID3 tags in MP3 files

ID3 tags are data fields added to an MP3 file that contain information about the file, such as the
song name, album name, and artist name.
To read ID3 tags from an MP3 file, use the
the names of ID3 tags included in the MP3 file being loaded. To determine when ID3 tags for a
downloading MP3 file are available, use the
version 1.0, 1.1, 2.3, and 2.4 tags; version 2.2 tags are not supported.
For example, the following code loads an MP3 file named favoriteSong.mp3 into the Sound
object named
song
shows the artist name and song name.
var song:Sound = new Sound();
song.onID3 = function () {
display_txt.text = "Artist: " + song.id3.TPE1 + newline;
display_txt.text += "Song: " + song.id3.TIT2);
}
song.loadSound("mp3s/favoriteSong.mp3", true);
Because ID3 2.0 tags are located at the beginning of an MP3 file (before the sound data), they
are available as soon as the file starts downloading. ID3 1.0 tags, however, are located at the end
of the file (after the sound data), so they aren't available until the entire MP3 file
finishes downloading.
