DOLBY 430 BACKGROUND NOISE SUPPRESSOR
The Dolby 430 Series is a background
noise suppressor system for reducing the
broadband noises such as wind or traffic rum-
ble that often mar location recordings. Many
mixers in film and television postproduction
already rely on Dolby Laboratories’
Cat. No. 43, a background noise suppression
unit based on a modified version of Dolby
A-type noise reduction. The 430 Series takes
this concept further by using a modified ver-
sion of Dolby SR’s patented combination of
fixed and sliding bands to give more stable
signal handling and a significantly reduced
chance of audible side effects
DOLBY NOISE REDUCTION
Dolby noise reduction is a family of
signal processes that reduce the noise
inherent in analog recording media,
without affecting the sound being
recorded. While they differ in perfor-
mance and details of operation, all
Dolby NR systems are complementary
processes that first encode the music
when it is recorded, then decode it
when it is played back. They also treat
soft signals separately from loud ones,
and vary the NR action with frequency
to avoid the side effects typical of other
systems.
Dolby A-type noise reduction, intro- duced in 1965, was originally intended for use by professional recording studios to make quieter master tape recordings. In the early 1970s its use was extended to film studios and motion picture release prints to make films sound better.
Dolby SR (spectral recording), intro-
duced in 1986, was designed not only to
provide more noise reduction than
A-type, but also to enable analog master
recordings that equal or surpass 16-bit
digital recordings with respect to overall
dynamic range. Today, analog with
Dolby SR is still a preferred format for
some musicians, producers, and record-
ing and mastering facilities, and is the
standard format for the analog sound-
tracks of virtually all feature films.
