MovieClip class 61

Example

The following example turns on echo suppression if the user selects a CheckBox instance

called

useEchoSuppression_ch. The ProgressBar instance called activityLevel_pb

displays the current activity level of the audio stream.

var useEchoSuppression_ch:mx.controls.CheckBox;

var activityLevel_pb:mx.controls.ProgressBar;

this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());

var active_mic:Microphone = Microphone.get();

sound_mc.attachAudio(active_mic);

activityLevel_pb.mode = "manual";

activityLevel_pb.label = "Activity Level: %3";

useEchoSuppression_ch.selected = active_mic.useEchoSuppression;

this.onEnterFrame = function() {

activityLevel_pb.setProgress(active_mic.activityLevel, 100);

};

var chListener:Object = new Object();

chListener.click = function(evt:Object) {

active_mic.setUseEchoSuppression(evt.target.selected);

};

useEchoSuppression_ch.addEventListener("click", chListener);

The MovieClip.getNextHighestDepth() method used in this example requires Flash Player

7 or later. If your SWF file includes a v2 component (version 2 of the Macromedia

Component Architecture), use the DepthManager class from the component framework

instead of the

MovieClip.getNextHighestDepth() method.
