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.
