Audio Recording Flash Media Server

We are running Flash Media Server 3.5. I require assistance capturing audio from a mic and playing it back. These will be two separate flash apps. You will be responsible for writing the back end classes as well as assisting with integration into a larger application (should be minimal with proper commenting and explanation). To recap we need 1 app to record (and preview your recording), and 1 app to just playback. This should be trivial for anyone familiar with FMS. Only AS3 is acceptable in proper OO format.
