提问by abduIntegral
Can somebody help me on how to capture audio from default microphone using HTML5? There are many samples available, but none of them seem to working. I have tried Audio capturing with HTML5As it only works with chrome with flags enabled. but it's getting NavigatorUserMediaError. The video icon on the address bar has a red cross sign and its tooltip says 'this page has been blocked from accessing your camera and microphone'

// success callback when requesting audio input stream
function successCallback(stream) {
var audioContext = new (window.webkitAudioContext)();
// Create an AudioNode from the stream.
var mediaStreamSource = audioContext.createMediaStreamSource( stream );
// Connect it to the destination to hear yourself (or any other node for processing!)
mediaStreamSource.connect( audioContext.destination );
}
function errorCallback() {
console.log("The following error occurred: " + err);
}
navigator.webkitGetUserMedia( {audio:true}, successCallback, errorCallback );

make sure you start the demo from a webserver - simply copy/paste & start from file system won't work - in chrome you never get access to the mic this way.
确保您从网络服务器启动演示 - 简单地复制/粘贴并从文件系统启动是行不通的 - 在 chrome 中，您永远无法以这种方式访问麦克风。

Recently (not sure when) Chrome added the requirement that the page be accessed over SSL to enable getUserMedia.
最近（不确定何时）Chrome 添加了通过 SSL 访问页面以启用 getUserMedia 的要求。
