MACROMEDIA FLASH 8-ACTIONSCRIPT 2.0 LANGUAGE - Gain (Microphone.gain Property)

Microphone 787
Example
The following example displays the activity level of the current microphone in a ProgressBar
instance called
activityLevel_pb.
var activityLevel_pb:mx.controls.ProgressBar;
activityLevel_pb.mode = "manual";
activityLevel_pb.label = "Activity Level: %3%%";
activityLevel_pb.setStyle("themeColor", "0xFF0000");
this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());
var active_mic:Microphone = Microphone.get();
sound_mc.attachAudio(active_mic);
this.onEnterFrame = function() {
activityLevel_pb.setProgress(active_mic.activityLevel, 100);
};
active_mic.onActivity = function(active:Boolean) {
if (active) {
var haloTheme_str:String = "haloGreen";
} else {
var haloTheme_str:String = "0xFF0000";
}
activityLevel_pb.setStyle("themeColor", haloTheme_str);
};
The MovieClip.getNextHighestDepth() method used in this example requires Flash Player
7 or later. If your SWF file includes a version 2 component, use the version 2 components
DepthManager class instead of the
MovieClip.getNextHighestDepth() method.

this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());
var active_mic:Microphone = Microphone.get();
sound_mc.attachAudio(active_mic);
