reducing 'plosives (explosive "P" sounds) in recording

This is caused by the wind from your mouth hitting the screen of the microphone. This problem can be eliminated or greatly reduced by placing microphone slightly off from directly in front of your mouth, either to the side, above, or below. Another solution is to use a popscreen, or make a homemade one using pantyhose stretched over a coathanger, place between microphone and mouth (to block the puff of air).
