Here are some tips to help you get better quality voice recordings using equipment you already have (iPhone, smart phone, iPad, mp3 player, laptop, desktop computer, etc). This is addressing TECHNIQUE.

All other things being equal, a better microphone would improve the overall sound quality, however, good technique with a mediocre microphone is better than bad technique with a good microphone.

Here’s how to get the best quality recording:

• Place microphone 8 – 12 inches away from the sound source.
• Do you pop your “P’s”? Try this: put your hand about an inch from your lips and say “People tend to pop their P’s.” Did you feel your breath on your hand? If your breath hits the microphone it will make an unwanted noise. To avoid this, position microphone slightly off axis so your breath does not contact the microphone. Or use a “pop filter”.
• Set the microphone on a stable surface with the microphone pointing towards you, (but off axis from your mouth to avoid popping P’s).
• Avoid touching or bumping into the microphone while recording
• Hand-held recorders can be place on a stable surface. If you must hold the device, be sure to hold it steady while recording. Moving the device may cause unwanted noise.
• Control for any unwanted noise as much as possible
  • Turn off noise makers: phones, fans, extra computers, florescent lights.
  • Put a “Do Not Disturb” sign on your door
  • Choose a time of day when environment is quieter
• Record narration at a time of day when you are at your best.
• Listen to a test recording using headphones, to check for any problems.
