# Microphone.setGain()

#### Availability

Flash Player 6.

#### Usage

    activeMicrophone.setGain(gain)

#### 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 myMic = Microphone.get();
    if (myMic.gain > 55){
    	myMic.setGain(55);
    }
