Microphone 797
Parameters
gain:Number - An integer that specifies the amount by which the microphone should boost
the signal. Valid values are 0 to 100. The default value is 50; however, the user may change
this value in the Flash Player Microphone Settings panel.
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);
The MovieClip.getNextHighestDepth() method used in this example requires Flash Player
7 or later. If your SWF file includes a version 2 component, use the version 2 components
DepthManager class instead of the
MovieClip.getNextHighestDepth() method.
