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.

Difficulty:

Moderately Easy

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.
