How to Use a Microphone to Record Speech

When used correctly, a decent microphone will pick up your voice without distortion. It will also eliminate any hollow sound, as well as unwanted pops, buzzing, hissing or roaring.

    Instructions

    Things You'll Need

    • Computer Microphones
    • Microphones
      • 1

        Use a unidirectional microphone with a PA system, for dictation, broadcasting or other situations where you only want to pick up an individual voice.

      • 2

        Consider using a unidirectional, cardioid or stereo microphone for interviewing.

      • 3

        Choose an omnidirectional mike for recording lectures or meetings. Aim the microphone at the speaker during a lecture.

      • 4

        Use a lavaliere (clip-on) microphone when you need to have your hands available and aren't using a podium.

      • 5

        Follow the instructions in your manual for placing the microphone the proper distance from the speaker.

      • 6

        Move the microphone closer to the speaker if the sound is hollow or it sounds like the speaker is in a tunnel. Test the sound on the PA system or make a brief test recording to determine the best distance.

      • 7

        Pull the microphone farther away from the speaker if the sound is distorted.

      • 8

        Keep the microphone away from computers, heat and air ducts, electrical devices not related to its use, and fluorescent lights.

      • 9

        Maintain a distance between the microphone and PA (or computer) speakers to avoid feedback.

      • 10

        Set the microphone level as high as possible without distorting (exceeding 100 VU or going into the red on a recording meter) or causing feedback.

      • 11

        Use a windscreen to prevent unwanted sounds ("p" sounds making an unpleasant popping noise) and hissing ("s" sounds making a sibilant, hissing noise).

      • 12

        Test the microphone and sound system before speeches or presentations.

      • 13

        Use a magnetically shielded microphone with a computer.

      • 14

        Employ a close-talk microphone (one that is built into a headset) for word processing with voice-recognition software. If a microphone is included with the software, use it.

      • 15

        Use a close-talk or stick-on microphone for computer command and control.

    Tips & Warnings

    • Make an inexpensive windscreen by cutting a piece out of a Nerf ball and wrapping it about the microphone.

    • Try a unidirectional microphone from a distance of 6 to 8 inches.

    • Visit the Related Sites to learn about critical distance for professional uses.

    • Get familiar with how your voice sounds before a presentation.

    • Avoid touching a microphone attached to a podium. Adjust the height and angle before the audience arrives.

    • Try not to move your hand on a handheld microphone. Remember that anything touching the microphone will make a loud, unpleasant noise.

      This is very difficult to follow since I don't know much about microphones.
