Mic audio capture and playback

Question

I've been developing in flash for a while now and now I have
a job developing flash and actionscript 3.0. I have come across a
project with a simple concept but I have found it difficult to
implement.
What I want to do is allow the user to click a button and
record their voice and then I want them to click another button and
play it back. I don't need to save or store it and I don't have
access to a flash media server or any alternative.
Is this possible to do and if so could someone please point
me in the right direction.
Thank you

Here you go.  I use this script so I know it works.  You need to have at least flash player 10.
You need 3 buttons.  1 record button - linkage = micRec , 1 play button - linkage = soundPlay  and one stop recording button - linkage = stopRecord
i keep the stop button off the stage and have it moved onto the stage when the record button is pushed.  Then finally move both the record and the stop recording button off the stage when the stop recording button is pushed.
micRec.addEventListener(MouseEvent.CLICK,recordMic);
function recordMic(event:MouseEvent){
micRec.x = -250;
stopRecord.x = 117;
const DELAY_LENGTH:int = 4000;
var mic:Microphone = Microphone.getMicrophone();
mic.setSilenceLevel(0, DELAY_LENGTH);
//mic.gain = 80;
mic.rate = 25;
mic.addEventListener(SampleDataEvent.SAMPLE_DATA, micSampleDataHandler);
stopRecord.addEventListener(MouseEvent.CLICK,SREC);
var soundBytes:ByteArray = new ByteArray();
function micSampleDataHandler(event:SampleDataEvent):void
    while(event.data.bytesAvailable)
        var sample:Number = event.data.readFloat();
        soundBytes.writeFloat(sample);
function SREC(event:MouseEvent):void
stopRecord.x = -250;
    mic.removeEventListener(SampleDataEvent.SAMPLE_DATA, micSampleDataHandler);
    soundBytes.position = 0;
    var sound:Sound = new Sound();
    sound.addEventListener(SampleDataEvent.SAMPLE_DATA, playbackSampleHandler);
soundPlay.addEventListener(MouseEvent.CLICK,SP1);
function SP1(event:MouseEvent){
soundBytes.position = 0;
    sound.play();
function playbackSampleHandler(event:SampleDataEvent):void
    for (var i:int = 0; i < 8192 && soundBytes.bytesAvailable > 0; i++)
        var sample:Number = soundBytes.readFloat();
        event.data.writeFloat(sample);
        event.data.writeFloat(sample);
