The
settings for
general
programming
provide the
best overall
processing
for a
variety
of
typical television
programming. Output
levels
and
frequency spectrum
are
consistent.
Excessive
commercial
loudness
is
avoided.
The
settings for fine
arts
programming
preserve the
wider dynamic
ranges
of
clas-
sical
music and
similar
programming. These
settings result
in less
consistency of
loudness and
dynamic
range.
The
settings for
music
video
programming
produce
a
somewhat more
heavily pro-
cessed
sound
typical
of
conservatively
processed popular
music on
FM
radio.
These
settings will
produce
quite consistent
results
from
a
wide
variety
of source
material.
