DE-EssEr
Introduction
DeEssingisawell-knowndynamicstoolmadeforremoving
unwanted sibilant sounds. This version in System 6000 is
improved significantly - e.g. with 48bit internal processing -
enablingtheprocesstobeperformedfrom100Hzto20kHz
giving the option to also use it as e.g. a de-popper.
A unique feature allowing the Threshold to operate either
Relatively to average level of the signal or Absolute to
0dBFS,makestheDeEsserworkextremelymusicale.g.on
vocals that have a constant flaw regardless of the level.
TheDeEsserisoperatinginStereo,Dual-monoorM/S
processing modes.
Threshold
WhentheinputlevelexceedstheThreshold,theDeEsser
will be in operation.
Threshold performance depends on the ‘Threshold
Mode’setting(RelativeorAbsolute)onthesetup
page.
Ratio
The Ratio of the gain reduction. When the Ratio is set
to 4:1 it means that for every 4dB the defined frequency
range rises, the output level increases by only 1dB.
Attack
TheAttacktimeistheresponsetimethattheDeEsser
uses to reach the gain reduction specified by the Ratio
parameter.
Release
Releasesetsthefall-backtimeoftheDeEsser,afterthe
signal drops below the Threshold.
Frequency
SetsthecenterfrequencyoftherangetheDeEsserwill
operate in.
Curve
Sets the bandwidth or Lo/Hi shelf setting of the range the
DeEsserwillworkin.
Side Chain
Pressing Sidechain enables to monitor the part of
thesignalthatisdefinedbytheFrequencyandCurve
parameters.ThisisthepartofthesignalthattheDeEsser
will“compress”wheninoperation.AdjustingtheFrequency
and Curve parameters when monitoring the sidechain,
makesitaloteasiertohearwherethesibilantproblems
occur in the signal.
Inlevel Left and Right
Range:Offto+12dB
AdjuststheInputlevelforthetwochannels.
Outlevel Left and Right
Range:Offto+12dB
AdjuststheOutputlevelforthetwochannels.
Phase Invert Left and Right
Applies Phase inversion of the respective Input channel.
Threshold Mode
Decides how the Threshold shall react. When set to
Relative, the Threshold will be relative to the average
level of the signal. This means that also soft signals
areprocessed.Forsignalswheretheaveragelevelis
determined by signals outside the frequency range set,
for example, a vocal with sibilance, the Relative setting is
useful and very musical. When Mode is set to Absolute,
theThresholdsetreferstofullscale,0dBFS,andis
therefore well suited for limiting the maximum level in a
specified frequency range, e.g. the bass.
