useEchoSuppression (Microphone.useEchoSuppression property)

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.

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 version 2 component, use the version 2 components' DepthManager class instead of the MovieClip.getNextHighestDepth() method.
