Play an AudioSource

Hi guys, i'm working on a script that register save and play audio from microphone.

I did almost all the only thing that i've to fix is the audio.Play();

this is my code:

 private var buttonWidth = Screen.width * 0.2;
 private var buttonHeight = Screen.width * 0.05;
 private var buttonX = Screen.width *0.01;
 private var buttonY = Screen.width *0.01;
 private var micIn : boolean = false;
 private var getAudioSource : AudioClip;
 private var deviceName : String;
 
 
 
 function Start() {
     if(Microphone.devices.Length <= 0){
         Debug.Log("Microphone not Connected");
     }else{
         micIn = true;
         for(var i : int = 0; i < Microphone.devices.length; i++){
             Debug.Log(Microphone.devices[i]);
             deviceName = Microphone.devices[i];
         }
     }    
 }
 
 function registerAudio() {
     Debug.Log("Recording Audio");
     getAudioSource = Microphone.Start(deviceName , false, 10, 44100);
 }
 
 function stopRecording(){
     Debug.Log("Stop Recording");
     Microphone.End(deviceName);
     
 }
 
 function saveAudio(){
     SavWav.Save("registerAudio", getAudioSource); 
 }
 
 function playAudio(){
     
     getAudioSource.Play(); 
 }
 
 function OnGUI(){
     if(micIn){
         if(!Microphone.IsRecording(deviceName)){
             if(GUI.Button(Rect(buttonX,buttonY, buttonWidth, buttonHeight), "Record")){
                 registerAudio();
             }
         }else{
             if(GUI.Button(Rect(buttonX, buttonY, buttonWidth, buttonHeight), "Stop Recording")){
                 stopRecording();
             }
         }
 
         if(GUI.Button(Rect(buttonX,buttonY+(buttonHeight*1.2), buttonWidth, buttonHeight), "PlayAudio")){
             playAudio();
         }
         
         if(GUI.Button(Rect(buttonX, buttonY+((buttonHeight*2)*1.2), buttonWidth, buttonHeight), "SaveAudio")){
             saveAudio();
         }
         
         if(Microphone.IsRecording(deviceName)){
             GUI.Label(Rect(buttonWidth +50, 10, buttonWidth, buttonHeight), "Recording");
         }else{
             GUI.Label(Rect(buttonWidth +50, 10, buttonWidth, buttonHeight), "Not Recording");
         }
     }
 }

Two things i found:

if i add to getAudioSource, where microphone register audio datas , .clip i can play it but then i can't save with SavWav class. there is any other way to play what i recorded without putting .clip to getAudioSource?
