Basic iPhone App Responds To Mic Input

I need a very basic iPhone application built that when launched, monitors the input of the built in microphone of the iPhone and perform actions based on the audio level.? If it is quiet, the the application will display one image, and if the audio level is high, it will display another image.? ? This is all the application needs to do, as it is just the starting point for a larger application, so no frills or other things are needed. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
