Develop a flash guitar tuner

I need someone to write some code to get the fundamental frequency from the microphone input. It must be as precise as YIN technique, as Tune!It technique ([login to view URL]) or as APTuner. This may be helpful: [login to view URL] (demo) [login to view URL] (source code) YIN application, documentation and source code are attached (java). I also attached YIN documentation The SamplaDataEvent class may be helpfull. The final code must be in ActionScript, and I'll need it with comments and ready to be compiled. The compiled SWF must show the gotten frequency on screen.
