var active_mic:Microphone = Microphone.get();

sound_mc.attachAudio(active_mic);

gain_pb.label = "Gain: %3";

gain_pb.mode = "manual";

gain_pb.setProgress(active_mic.gain, 100);

gain_nstep.value = active_mic.gain;

function changeGain() {

active_mic.setGain(gain_nstep.value);

gain_pb.setProgress(active_mic.gain, 100);
