For optimal results, your condenser or dynamic microphone should be approximately 4 to 12 inches away from your face. If the microphone is too close, it will pick up too much of the low frequency sounds in your voice.
What direction should my mic be?
Once you find the sweet spot, place the cardioid mic with its capsule pointing perpendicular to your palm toward the sound source. This is effective with all cardioid-type mics and works fairly well with bidirectional mics as well.
