拍摄视频工作正常。
使用PhoneGap的3.0.0或2.9.0与PhoneGap的建设。
Using Phonegap 3.0.0 or 2.9.0 with Phonegap Build.

<head>
<title>Capture Audio</title>
<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8" src="json2.js"></script>

// Called when capture operation is finished
//
function captureSuccess(mediaFiles) {
var i, len;
for (i = 0, len = mediaFiles.length; i < len; i += 1) {
uploadFile(mediaFiles[i]);
}
}
// Called if something bad happens.
//
function captureError(error) {
var msg = 'An error occurred during capture: ' + error.code;
navigator.notification.alert(msg, null, 'Uh oh!');
}
// A button will call this function
//
function captureAudio() {
// Launch device audio recording application,
// allowing user to capture up to 2 audio clips
navigator.device.capture.captureAudio(captureSuccess, captureError, {limit: 2});
}
// Upload files to server
function uploadFile(mediaFile) {
var ft = new FileTransfer(),
path = mediaFile.fullPath,

ft.upload(path,
"http://my.domain.com/upload.php",
function(result) {

推荐答案
这是不是一个确切回答你的问题，而是一个工作的选择。
This is not an exactly answer to your problem, but a working alternative.
而不是使用的 org.apache.cordova.media捕获的的我试过 org.apache.cordova.media
Instead of using org.apache.cordova.media-capture I tried org.apache.cordova.media.
下面是一个小例子：
function recordAudio() {
var src = "myrecording.amr";
var mediaRec = new Media(src,
// success callback
function() {
console.log("recordAudio():Audio Success");
},
// error callback
function(err) {
console.log("recordAudio():Audio Error: "+ err.code);
});
// Record audio
mediaRec.startRecord();
// Stop recording after 10 seconds
setTimeout(function() {
mediaRec.stopRecord();
}, 10000);
}
Unfortunaly每个设备使用自己的声音codeC和Android中的情况下，它是AMR codeC。我能听使用 MPC（Windows）中备案。但是，如果你要上传的文件，并与其他用户一起分享，你必须其转换。
Unfortunaly each device uses their own audio codec and in case of Android it is the AMR Codec. I was able to listen to the record using MPC (Windows). But if you want to upload the file and share it with other users, you'll have to convert it.
如果你没有找到 myrecording.amr 文件：它位于设备的根目录。我也没弄清楚如何临时存储在应用程序缓存文件夹本身，这是现有的文件。
If you do not find the myrecording.amr file: It is located on devices' root. I did not figure out how to store files temporary in the application cache folder itself, which is existing.
10秒的记录具有＆LT; 20KB大小。
A 10 second recording has < 20kb size.
AMR 8000Hz mono 12kbps [Audio]
这是非常糟糕的质量。 Unfortunaly似乎有没有可能提高质量。
Which is very bad quality. Unfortunaly there seems to be no possibility to increase the quality.
