Parameters
gain
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.
Returns
Nothing.
Description
Method; sets the microphone gain—that is, the amount by which the microphone should
multiply the signal before transmitting it. A value of 0 tells Flash to multiply by 0; that is, the
microphone transmits no sound.
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 ensures that the microphone gain setting is less than or equal to 55.
var active_mic:Microphone = Microphone.get();
if (active_mic.gain > 55){
active_mic.setGain(55);
}
