When the Flash program loads into your web page, you might see a permissions dialog box like this:
Click the "Allow" button to allow recording.
Every time the web page loads, you will see the same permissions dialog box.
If you want the Flash plugin always to allow recording, you can tell it to "remember" the permissions.
Right-click on the Flash file, and from the contextual menu, click "Settings."
Click the radio button for "Allow," then click checkbox next to "Remember," then click OK
Now, you try it. This is a live audio recorder. Click the "Record" button to begin recording.
