Mic Input totally crashes flash

[RubenvDijk]

I am working on a project that plays a sound when the mic input does not detect any sound.
It works perfectly only one problem.
When I close the preview in flash I get no error but flash cs5 totally crashes.
Anybody got a clue on why this happens?
I suspect the computer cash fills up with the information about the mic input and can't handle it anymore so crashes,
but I am not sure and don't know how I could fix this. I do know when the animation_mc.play(); is removed it does not crash.
(In my animation_mc are the audio files that should be played when the mic does not detect an input.)

Here is my main code

var verdergaan = false;



var mic:Microphone = Microphone.getMicrophone();
mic.gain = 50;
mic.rate = 8;
mic.setLoopBack(true);
mic.soundTransform = new SoundTransform(0, 0);
mic.setSilenceLevel(20, 2000);

mic.addEventListener(ActivityEvent.ACTIVITY, this.onMicActivity);
mic.addEventListener(StatusEvent.STATUS, this.onMicStatus);

var micDetails:String = "Sound input device name: " + mic.name + '\n';
micDetails += "Gain: " + mic.gain + '\n';
micDetails += "Rate: " + mic.rate + " kHz" + '\n';
micDetails += "Muted: " + mic.muted + '\n';
micDetails += "Silence level: " + mic.silenceLevel + '\n';
micDetails += "Silence timeout: " + mic.silenceTimeout + '\n';
micDetails += "Echo suppression: " + mic.useEchoSuppression + '\n';



function onMicActivity(evt:ActivityEvent):void {
    trace("activating=" + evt.activating + ", activityLevel=" + mic.activityLevel);
    
    if(mic.activityLevel>20){
        //verdergaan = true;
        //trace(verdergaan);
        animation_mc.stop();
        trace("je hebt net gepraat");
        
        var t:Timer = new Timer(1000);
        t.addEventListener(TimerEvent.TIMER, onDelay);
        t.start()
        
        function onDelay(te:Event):void {
            if(mic.activityLevel<20){
                
                animation_mc.play();
                trace("je hebt net gepraat1");
                t.stop();
            }
        }
    }
        //verdergaan = true;
}


function onMicStatus(evt:StatusEvent):void {
    trace("status: level=" + evt.level + ", code=" + evt.code);
}

function luister(){
    
    if (verdergaan == true){
        animation_mc.play();
    }
}
setInterval(luister,3000);


stage.addEventListener(KeyboardEvent.KEY_DOWN, myKeyDown);
function myKeyDown(e:KeyboardEvent):void{
if (e.keyCode == Keyboard.SPACE){
animation_mc.play();
} 
}

Really hope someone can help me!

You shouldn't nest functions. You have defined onDelay inside onMicActivity. So each time onMicActivity executes you create a new timer and a new listener function on that new timer. You should probably move both the timer and onDelay outside onMicActivity to avoid creating several identical copies.

You should also use a repeating Timer and a TimerEvent listener rather than using setInterval, though that is mostly a matter of doing things in AS3 style rather than a performance issue.
