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.

public silenceLevel : Number [read-only]
An integer that specifies the amount of sound required to activate the microphone and invoke
Microphone.onActivity(true)
. The default value is 10.
Availability:
ActionScript 1.0; Flash Player 6
Example
The following example changes the silence level based on the user's input in a
NumericStepper instance called
silenceLevel_nstep
. The ProgressBar instance called
silenceLevel_pb
modifies its appearance depending on whether the audio stream is
considered silent. Otherwise, it displays the activity level of the audio stream.
var silenceLevel_pb:mx.controls.ProgressBar;
var silenceLevel_nstep:mx.controls.NumericStepper;
this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());
var active_mic:Microphone = Microphone.get();
sound_mc.attachAudio(active_mic);
silenceLevel_pb.label = "Activity level: %3";
silenceLevel_pb.mode = "manual";
silenceLevel_nstep.minimum = 0;
silenceLevel_nstep.maximum = 100;
silenceLevel_nstep.value = active_mic.silenceLevel;
var nstepListener:Object = new Object();
nstepListener.change = function(evt:Object) {
active_mic.setSilenceLevel(evt.target.value, active_mic.silenceTimeOut);
};
silenceLevel_nstep.addEventListener("change", nstepListener);
this.onEnterFrame = function() {
