Client-Side ActionScript Language Reference

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.
