For example, with
Loudness Shaping
enabled at a medium level, signals that fall below the
Target Level
setting have more gain added to middle frequencies than higher or lower frequencies. This preserves
the original spectral balance. Conversely, signals that fall above the
Target Level
setting will have middle
frequencies attenuated more than higher or lower frequencies. Because the
Loudness Shaping
parameter applies less gain to high and low frequencies, high or low frequency noise does not become
over-emphasized.

Presets
The Loudness Control feature uses four different presets (
Ultra-Light, Light, Medium
, and
Aggressive
).The table lists the values that each of these presets represents.
