Tips when using a microphone.
A good voiceover recording doesn’t require expensive
equipment or a well designed recording studio, nor does
it require a tremendous amount of experience or "know
achieve a good result. A little common sense and effort,
and a critical ear can work wonders.
Use a good quality microphone when recording your
voice. Ensure that you test levels a few times by
recording a test dialogue. Don't place the microphone
too close to your mouth in order to avoid sound
distortion in the recording. Explosions of air bursting
from the mouth, the lips and tongue can sound wet, and
“sss” sounds can overwhelm a recording.
The other thing to watch out for is "Reflections". If
you are speaking in to your microphone while close to a
hard surface such as a wall you will get reflected sound
from that surface. These reflections degrade the sound
quality. To avoid this try using a few cushions or
carpet as a surface that you are facing. This will
reduce reflections and improve sound quality.
