Color Model
: For heavy noise reduction of a particular environment such as machine
and instruments noise type, the more complex Color Model is recommended and the
dial once again runs values from 0.0 to 1.0. A user can choose the level of noise
filtering by varying the value of the dial. An increasing dial value increases the level
of noise filtering in the audio. A user who is uncertain of the level of noise for an
input can conveniently leave the dial in the 0.2-0.3 range.
4.1.8 Dynamic Listening Fatigue Reduction (DLFR):
This is an audio
sweetening
tool that conditions the temporal envelope of the
audio signal in multiple frequency bands. To smooth the audio the dial value should
be at high end and to let in more envelope dynamics dial value should be at lower end.
Figure 4.11: Dynamic Listening Fatigue Reduction Tool
The 6 vertical bars below the dial provide finer control over envelope
conditioning in individual frequency bands (with indicated center frequency values).
The higher the sliders the smoother is the audio in that band. There are two associated
slider controls which control respectively the tonal characteristics of overall audio and
the refinement level of envelope conditioning. For a new user, good initial setting for
all the DLFR controls may be found by selecting the “Music-General-purpose-Light”
