如何使用cordova錄製後獲取音頻文件

我正在使用cordova media插件來錄製voice.Once我已錄製它。我想把它發送到服務器。爲此，我正在使用FileUpload和FileTransfer.But我面臨着獲取錄製文件的問題。如何獲取錄製的音頻文件？我已經通過cordova文件插件文檔，但沒有正確理解。如何使用cordova錄製後獲取音頻文件

    <script> 
       var filename;   
       var mediaRec; 



      function recordAudio() { 
        filename = "myrecording "+new Date().getTime()+".amr"; 

        mediaRec = new Media(filename, onSuccess, onError); 
        mediaRec.startRecord(); 
      } 
      function onSuccess(){} 
      function onError(){} 
      function stopRecord(){ 
       mediaRec.stopRecord(); 
       sendAudio(); 

      } 

      function sendAudio(){ 

       var options = new FileUploadOptions(); 
           options.fileKey = "attachmentFileName"; 
           options.fileName = filename; 
           options.mimeType="audio/AMR"; 


           new FileTransfer().upload(filename,encodeURI("my url"), win, fail, options);
