如何關閉ActionAcript3中的麥克風

Question

如何關閉AS3中的麥克風？示例代碼如下。我想通過調用closeMicrophone（）函數來關閉（關閉）麥克風。

var microphone:Microphone = null; 
function openMicrophone():void{ 
    if(Microphone.isSupported){ 
     Security.showSettings(SecurityPanel.PRIVACY); 
     microphone = Microphone.getMicrophone(); 
     if(microphone != null){ 
      microphone.setLoopBack(); 
      microphone.setSilenceLevel(5, 2000); 
      }else{ 
      trace('No microphone found!'); 
      } 
     }else{ 
     trace('The Microphone class is not supported on this system!'); 
     } 
    } 
function closeMicrophone():void{ 
    // Here, I want to turn off microphone. 
    }

你想禁用話筒環回，對不對？然後再以false作爲參數再次調用setLoopBack方法。

function closeMicrophone():void{ 
    microphone.setLoopBack(false); 
    microphone = null; 
}
