this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());
var active_mic:Microphone = Microphone.get();
sound_mc.attachAudio(active_mic);
active_mic.onActivity = function(active:Boolean) {
if (active) {
activityLevel_pb.indeterminate = false;
activityLevel_pb.label = "Activity Level: %3%%";
} else {
activityLevel_pb.indeterminate = true;
activityLevel_pb.label = "Activity Level: (inactive)";
