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.

useEchoSuppression
(Microphone.useEchoSuppression property)
public useEchoSuppression : Boolean [read-only]
Property (read-only); a Boolean value of true if echo suppression is enabled, false otherwise.
The default value is false unless the user has selected Reduce Echo in the Flash Player
Microphone Settings panel.
Availability: ActionScript 1.0; Flash Player 6
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);
