I have written my program using the utorials on Audio Level Indicator available at Microsoft's website. In that they have used progress bar to indicate audio level bu i have modified it and used the Picture Clip Control to show the audio level. The picture is a bitmap on which i've drawn around 42 bars which shows different levels and depending upon the value of audio level, the corresponding bitmap is clipped and displayed in a picture box. Thus is looks like LED's moving up and down.
