Microphone.gain
Availability
■
Flash Player 6.
■
Flash Media Server (not required).
Usage
public gain : Number [read-only]
Description
Property (read-only); the amount by which the microphone boosts the signal. Valid values
are 0 to 100. The default value is 50.
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 v2 component (version 2 of the Macromedia
Component Architecture), use the DepthManager class from the component framework
instead of the
MovieClip.getNextHighestDepth()
method.
