Capturing Audio in PhoneGap

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 :

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 .

In this htdocs folder create a new folder say Audio .

Create a new text document in this Audio folder and name it as index.html

Now open the index.html file with Notepad++ and write the following code as given below :

<!--DOCTYPE HTML-->
<html>
<head>             <title>PhoneGap Camera</title>
			<style>
body{background:#000000;color:#ffffff;}
				#recordBtn{     display:block;
						border-radius:50%;
						width:200px;
						height:100px;
						background:red;
						color:#000000;
						margin: 30px auto;
				}
			</style>

<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-->
		document.addEventListener("deviceready",onDeviceReady,false);
		<!--PhoneGap is Ready-->
		function onDeviceReady()
{
			audioCapture = navigator.device.capture;
			$('#recordBtn').bind('touchstart',function(){
			getAudio();
			});
		}

		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 />';						}
	$('#recordBtn').before(output);
}
function onCaptureError(error)
{
	var  errMsg;
	switch(error.code)
	{
		case 0:      errMsg = 'Mic failed to record';
			    break;
case 1:      errMsg = 'Recording app is currently busy'
			    break;

case 2:	   errMsg = 'Invalid parameter';
			   break;
		
case 3:   errMsg = 'App was exited before the recording was complete';
			  break;
							
	  	case 4:  errMsg = 'Device does not support the audio capture request';
			  break;
	}
	alert('Error: '+errMsg);
    }
</script>
</head>
		<body>
			<button id="recordBtn">Record</button>
