Similarly, Threshold should be set high enough
that de-essing is triggered only by sibilants. If
the Threshold is set too low, a loud, non-sibilant
section of audio material could cause unwanted
gain reduction or cause sibilants to be over at-
tenuated.
To improve de-essing of material that has both
very loud and very soft passages, automate the
Threshold control so that it is lower on soft sec-
tions.
DeEsser Controls
Input Meter Indicates the level of the unproc-
essed input signal to the DeEsser.
Output Meter Indicates the output level of the
DeEsser.
Reduction Indicates the amount of gain reduc-
tion in dB. It remains at 0 dB level when the in-
put signal is below the threshold.
Threshold Sets the threshold level. Signals that
exceed this level will be compressed. Signals
that are below it will be unaffected. A setting of
0 dB is equivalent to no de-essing.
Frequency Sets the frequency band in which the
DeEsser operates. Frequencies in the specified
range will be gain reduced. To find the optimum
Frequency setting, sweep this control back and
forth during audio playback.
Key Listen Monitors the sibilant peaks used by
the DeEsser as a Key Input to trigger compres-
sion. This is useful for listening only to the sibi-
lance and fine tuning settings to remove them.
Mod Delay and Mod Delay II
The DigiRack Mod Delay and Mod Delay II plug-
ins provide time delay-based effects such as
echo, slap echo, doubling, chorusing, and flang-
ing. Mod Delay II improves on Mod Delay by
supporting tempo controls and sample rates up
to 192 kHz.
Mod Delay
(Pro Tools 5.3 and Earlier Only)
It is recommended that you only use Mod
Delay II for all new sessions. Use Mod De-
lay only for compatibility with existing ses-
sions. If you do not need to use Mod Delay,
move it from the Plug-Ins folder into the
Plug-Ins (Unused) folder. Mod Delay set-
tings can be imported into Mod Delay II.
