In this tutorial we will be creating an app which will have the recording functionality , so we will have a record button which when pressed will record the audio file for us .

  • To create an app with functionality of capturing audio in Phonegap follow the steps given below :

  1. First of all download and install the Xampp Server and gitbash in your machine and if it is already installed go to Xampp -> htdocs folder .
  2. In this htdocs folder create a new folder say Audio .
  3. Create a new text document in this Audio folder and name it as index.html
  4. Now open the index.html file with Notepad++ and write the following code as given below :
  5. <!--DOCTYPE HTML-->
    <head>             <title>PhoneGap Camera</title>
    				#recordBtn{     display:block;
    						margin: 30px auto;
    <script type="text/javascript" charset="utf-8" src="js/jquery.js"></script>
    	<script type="text/javascript" charset="utf-8" src="phonegap.js"></script>
    	<script type="text/javascript">
    		var audioCapture = '';
    		<!--Wait for the phoneGap to load-->
    		<!--PhoneGap is Ready-->
    		function onDeviceReady()
    			audioCapture = navigator.device.capture;
    		function getAudio()
    			audioCapture.captureAudio(onCaptureSuccess,onCaptureError,{limit: 1});
    function onCaptureSuccess(audioObject)
    var i, output ='';
    	for(i=0;i<audioObject.length; i++)
    		output += 'Name: '+ audioObject[i].name + '<br />' +
    			   'Full Path:  '+ audioObject[i].fullpath + '<br />' +
    			   'Type:  '+ audioObject[i].type + '<br />' +
    			   'Create On:  '+ new Date(audioObject[i].lastModifiedDate) + '<br />' +
    			   'Size:  '+ audioObject[i].size + '<br />';						}
    function onCaptureError(error)
    	var  errMsg;
    		case 0:      errMsg = 'Mic failed to record';
    case 1:      errMsg = 'Recording app is currently busy'
    case 2:	   errMsg = 'Invalid parameter';
    case 3:   errMsg = 'App was exited before the recording was complete';
    	  	case 4:  errMsg = 'Device does not support the audio capture request';
