We would like to draw a real time Amplitude graph for Mic input audio.
How should we read real time values for Amplitude for mic input audio?

You can find a plethora of examples on the web showing how to use the waveIn APIs, or the DirectSound  APIs, or the WASAPI APIs, or even something like libsound or portaudio for that matter.  All of them can get you microphone data.
