Logic Pro DeEsser 2
DeEsser 2 is a frequency-specific compressor, designed to compress a particular
frequency band within a complex audio signal. It is used to eliminate sibilance (overly
emphasized “s” sounds, especially in vocals, and plosives such as “t” sounds that can be
emphasized by compressor and saturation effects) from the signal. DeEsser 2 compresses
the signal dynamically, preventing the sound from becoming darker when no sibilance is
present. DeEsser 2 has extremely fast attack and release response times for the shortest
of transients, thus retaining a natural sound.
DeEsser 2 provides two operating modes that enable you to work with high or low level
signals. Also included are two filter shapes and range parameters that are used to define
and control the affected frequency range.
DeEsser 2 parameters
• Detection meter: Shows the input signal level of the selected frequency. Behavior of
the meter changes in Absolute or Relative mode. See Mode pop-up menu description.
• Detection max field: The maximum level of the selected frequency is shown. Click
to reset.
• Detection meter slider: Drag to set the Threshold, or amplification level, above which
gain reduction of the selected frequency is applied.
• Reduction meter: Shows the amount of gain reduction applied.
• Reduction max field: The maximum level is shown (peak hold). Click to reset.
• Reduction meter slider: Drag to set the maximum amount of dynamic gain reduction
applied to the selected frequency.
• Threshold knob and field: Set the Threshold, or amplification level, above which gain
reduction of the selected frequency is applied.
• Max Reduction knob and field: Set the maximum amount of dynamic gain reduction
applied to the selected frequency.
• Frequency knob and field: Set the center or maximum frequency of the detection filter,
depending on the chosen filter.
