is it possible to record voice using headphone in AS3

In Flash I have a Button called "button" and a TextField called "textfield".

import flash.events.MouseEvent;
import flash.external.ExternalInterface;
button.addEventListener(MouseEvent.CLICK, buttonClick);
// on button click call Javascript
function buttonClick(e:MouseEvent):void
{
    ExternalInterface.call("callFromFlash", "Hello from Flash");
}
// register call from Javascript
ExternalInterface.addCallback("callFromJS", callFromJS);
// display the message from Javascript
function callFromJS(s:String):void
{
    textfield.text = s;
}

In Javascript I use jQuery. If you want to use Javascript you'd better use it (or any other framework) or you won't have any hair left after fighting with certain Microsoft browsers In HTML I have a button with the ID "button".

// display the message from Flash
          function callFromFlash(arg){
                alert(arg);
            }
            
            jQuery(function($){init()});
            
            function init(){
                $("#button").click(buttonClick);
            }
// on button click send a message to Flash            
            function buttonClick(e){
                e.preventDefault();
                $("#flash")[0].callFromJS("Hello from JS");
            }
