Microphone.useEchoSuppression
551
Example
The following example enables the user to control the amount of time between when the
microphone stops detecting sound and when
Microphone.onActivity(false)
is invoked. The
user controls this value using a NumericStepper instance called
silenceTimeOut_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 silenceTimeOut_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";
silenceTimeOut_nstep.minimum = 0;
silenceTimeOut_nstep.maximum = 10;
silenceTimeOut_nstep.value = active_mic.silenceTimeOut/1000;
var nstepListener:Object = new Object();
nstepListener.change = function(evt:Object) {
active_mic.setSilenceLevel(active_mic.silenceLevel, evt.target.value*1000);
};
silenceTimeOut_nstep.addEventListener("change", nstepListener);
this.onEnterFrame = function() {
silenceLevel_pb.setProgress(active_mic.activityLevel, 100);
};
active_mic.onActivity = function(active:Boolean) {
if (active) {
silenceLevel_pb.indeterminate = false;
silenceLevel_pb.setStyle("themeColor", "haloGreen");
silenceLevel_pb.label = "Activity level: %3";
} else {
silenceLevel_pb.indeterminate = true;
silenceLevel_pb.setStyle("themeColor", "0xFF0000");
silenceLevel_pb.label = "Activity level: (inactive)";
}
};
