The SPL DeEsser has the following parameters:
About the Auto Threshold function
Conventional de-essing devices all have a threshold pa-
rameter. This is used to set a threshold for the incoming
signal level, above which the device starts to process the
signal. The SPL DeEsser however has been designed for
utmost ease-of-use. With Auto Threshold on (the button
lights up) it automatically and constantly readjusts the
threshold to achieve an optimum result. If you still wish to
determine for yourself at which signal level the SPL
DeEsser should start to process the signal, deactivate the
Auto Threshold button. The SPL DeEsser will then use a
fixed threshold.
When recording a voice, usually the de-esser's position in
the signal chain is located after the microphone pre-amp
and before a compressor/limiter. This is useful, as it keeps
the compressor/limiter from unnecessarily limiting the
overall signal dynamics by reacting to excessive sibilants
and s-frequencies.
The Auto Threshold function keeps the processing on a
constant level. The input threshold value is automatically
and constantly adjusted to the audio input level. Even level
differences of say 20dB do not have a negative impact on
the result of the processing. The input levels may vary, but
processing remains constant.
EnvelopeShaper (Cubase only)
EnvelopeShaper can be used to cut or boost the gain of
the Attack and Release phase of the audio material. You
can either use the knobs or drag the breakpoints in the
graphic display to change parameter values. Be careful
with levels when boosting the gain and if needed reduce
the Output level to avoid clipping.
The following parameters are available:
Parameter Description
S-Reduction Controls the intensity of the de-essing effect. We recom-
mend that you start with a value between 4 and 7.
Level display Indicates the dB value by which the level of the sibilant or
s-frequency is reduced. The display shows values be-
tween 0dB (no reduction) and minus 20dB (the s-fre-
quency level is lowered by 20dB). Each segment in the
display represents a level reduction of 2dB.
Auto Threshold See separate description below.
Male/Female This sets the s-frequency and sibilant recognition to the
characteristic frequency ranges of the female or male
voice. The center frequency of the bandwidth at which the
SPL DeEsser operates is located in the 7kHz range for the
female voice and in the 6kHz range for the male voice.
Parameter Description
Attack (-20–20dB) Changes the gain of the Attack phase of the signal.
Length (5–200ms) This determines the length of the Attack phase.
Release (-20–20dB) Changes the gain of the Release phase of the signal.
Output (-24–12dB) Sets the output level.
