Microphone.setRate() 545

You can think of this setting like a volume knob on a stereo: 0 is no volume and 50 is normal

volume; numbers below 50 specify lower than normal volume, while numbers above 50 specify

higher than normal volume.

Example

The following example uses a ProgressBar instance called gain_pb to display and a

NumericStepper instance called

gain_nstep to set the microphone’s gain value.

this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());

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);

}

gain_nstep.addEventListener("change", changeGain);
