Sound.duration 683
The following example loads several songs into a SWF file. A progress bar, created using the
Drawing API, displays the loading progress. When the music starts and completes loading,
information writes to the log file. Add the following ActionScript to your FLA or AS file.

this.getNextHighestDepth());

pb.createEmptyMovieClip("vBar_mc", pb.getNextHighestDepth());
pb.createEmptyMovieClip("stroke_mc", pb.getNextHighestDepth());
pb.createTextField("pos_txt", pb.getNextHighestDepth(), 0, pb_height,
pb_width, 22);
pb._x = 100;
pb._y = 100;
