Usage

public onActivity = function(active:Boolean) {}

Parameters

active A Boolean value set to true when the microphone starts detecting sound, false when it stops.

Returns

Nothing.

Description

Event handler; invoked when the microphone starts or stops detecting sound. If you want to respond to this event handler, you must create a function to process its active value.

To specify the amount of sound required to invoke Microphone.onActivity(true), and the amount of time that must elapse without sound before Microphone.onActivity(false) is invoked, use Microphone.setSilenceLevel().

Example

The following example displays true or false in the Output panel when the microphone starts or stops detecting sound.

var active_mic:Microphone = Microphone.get();
_root.attachAudio(active_mic);
active_mic.onActivity = function(mode){
    trace(mode);
}
