CleanComp
CleanComp is a simple compressor that allows you to limit loud sounds,
while at the same time boosting the overall loudness of the audio material.
DeClicker
The DeClicker plug-in is specifically designed to eliminate single “clicks”
or “pops” in a recording. One typical application is to clean up recordings
made from vinyl records, but you may also find it useful for removing pops
from microphone switches, oxidized connector noises, clicks from sync
problems when transferring material digitally, etc.
• Note that the DeClicker module is not optimized for crackles (a series of
short clicks).
However, as it is often hard to distinguish between clicks and crackles, you might also be
able to use it to improve your recording in this respect.
• If the recording also contains background noise (hiss), you may want to
combine DeClicker with the DeNoiser plug-in.
How DeClicker works
The Declicker process is divided into two steps:
• Analysis – when the audio signal passes through DeClicker, the selected analysis
algorithm finds the clicks in the recording. You provide input to the analysis pa-
rameters by selecting a Mode and the Threshold and DePlop parameters.
• Removal – a de-click algorithm is applied to the audio, removing the clicks.
In many cases, the original audio material “hidden” underneath a click cannot be restored.
This means there will be a gap once the click has been removed. DeClicker has the ability
to automatically “redraw” the hence missing parts of the waveform. This feature can also be
used to remove tape dropouts with a length of up to 60 samples (just above one millise-
cond at 44.1kHz).
Parameter Description
Ceiling (0dB~-24) This setting determines the maximum level at the CleanComp outputs.
Softness (-5~5) This parameter affects the way CleanComp operates. A high setting will
maximize the perceived loudness effect but can in some cases result in
a slight harshness of the sound. Adjust this parameter to optimize the
balance between sound quality and the desired effect.
Out Gain
(0~+24dB)
This allows you to adjust the output level from CleanComp. Use this to
(typically) raise the loudness of the signal. Use extreme boost settings
with caution as they can induce distortion.
