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);
