ActionScript 3.0: produce an online voice recorder in flash

Following the instruction on active tuts website:
http://active.tutsplus.com/tutorials/actionscript/create-a-useful-audio-recorder-app-in-actionscript-3/
I designed an online voice recorder as below. The design used  the MicRecorder class from google code library. When you click the button,  the sound around is recorded by your microphone.  When you click stop, the sound is saved in your local computer.
