this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());
var active_mic:Microphone = Microphone.get();
sound_mc.attachAudio(active_mic);
var rate_array:Array = new Array(5, 8, 11, 22, 44);
rate_cb.dataProvider = rate_array;
rate_cb.labelFunction = function(item:Object) {
return (item+" kHz");
};
for (var i = 0; i<rate_array.length; i++) {
if (rate_cb.getItemAt(i) == active_mic.rate) {
rate_cb.selectedIndex = i;
break;
}
}
function changeRate() {
active_mic.setRate(rate_cb.selectedItem);
rate_lbl.text = "Current rate: "+active_mic.rate+" kHz";
}
rate_cb.addEventListener("change", changeRate);
rate_lbl.text = "Current rate: "+active_mic.rate+" kHz";
