Intelligent Loudness Control (LOUDNESS):
Figure 4.2: Loundness Control
This module detects the current input
stereo
loudness and controls the output
stereo
loudness depending on the two sliders value.
•
The first slider is for the release time, to control how fast the audio loudness
should get adapted to desired level. For fast adaptation slider should be at the
left most position and vice versa.
•
The second slider is for the attack time. Applied gain will last over a definite
period of time defined as attack time. If attack time is set to left most side ,
then gain will change very instantaneously (which is not very desired as it may
cause some distortion or poor quality audio).
•
The third slider is for the output loudness level indication, to set the loudness
0
dB
below the maximum level i.e., 0
dBFS
, slider should be at the left most
position, and for -15
dB
below the maximum i.e. least allowed loudness (-15
dBFS
); slider should be right most position.
