Some examples: By dragging the dot on the blue line, you can find the optimum
distance from the sound source to the microphone from 1cm to 1000cm.
A low-loudness singer & use of Pop-fi lter/Pop-shield
Example 1: A low-loudness singer's loudness is about 60dB (Peak), and 40dB (normal)
witch is about 20dB of dynamic range (60dB – 40dB = 20 dB) .
The "Set Gain to" is at 40.18dB and indicates, that setting the gain knob to about 80%
of full gain would be close to a optimum setting.
In the "real world" it is difficult to be accurate with gain settings, and a singer
typically moves around about 5cm to 50cm when performing. So defining the
minimum + maximum distance to the microphone and maximum gain when closest to
the microphone; is important to get a good distortion free recording.
Using a Pop-filter/Pop-shield at a distance of about
10-15cm as on the picture to the right. Will greatly
reduce "plosive" or moving Pop-"winds". When
saying/singing English words with [ p ], [ t ], [ k ] like
"pat", "kid", "bag", usually those "Pop" sounds can
overload the the signal for a brief time. Plosive in other
languages may be different.
This would risk of distortion and/or the need for extra
sound processing/effects to remove the problematic
Pop's.
The Pop-filter/Pop-shield also limits the amount of
moist/saliva mouth from speech and singing, that
otherwise would have landed on the microphone. The
microphone also has a longer lifespan in a dryer
