12.3 Sonnox DeClicker 327
Input Level Meter
The Input Meter is designed to give exactly 1dB per LED for the top 18dB of dynamic
range, and 2dB per LED thereafter. This gives a clear and intuitive impression of the
working headroom.
Input Gain Trim Touch Pad (dB)
This allows you to adjust the input signal level by up to ±12dB.
Sensitivity Fader and Touch Pad (%) (Pop; Click; Crackle)
This controls the sensitivity of the detection circuits. Fully sensitive might allow the
detection circuit to react to low level signals and possibly mis-classify programme as
pops or clicks. Stronger pops and clicks will require a less sensitive setting.
In Button (Pop; Click; Crackle)
This button enables the pop, click or crackle removal processing. It is important to
note that with this button "off" (i.e. the repair processing is disabled), the pop, click or
crackle detection circuit is still enabled and the detect display will still show the degree
of event detection.
Detect Meter Display (Pop; Click; Crackle)
The Detect meter display combines two indications. The main rising column indicates
the sum of the energy of events that have been detected. With the "In" button de-
selected (i.e. the repair circuit disabled), this column is colored orange/red. With the
repair circuit active the column is colored blue. The bottom segment of the meter is an
indication of each individual detected event.
Output Level Meter (dB)
The output meter is designed to give exactly 1dB per LED for the top 18dB of dynamic
range, and 2dB per LED thereafter. There is a peak-hold feature that holds the highest
peak, helping to give a better impression of the working dynamic range.
Output Gain Trim Touch Pad (dB)
This allows you to reduce the output level by up to 12dB. Dithering is applied after
output gain control, so it may be necessary to reduce this value by a small amount to
avoid clipping.
Quick-Start Guide for the De-Clicker
The De-Clicker is very simple and intuitive to use. It is generally wise to repair the larger and
more energetic events first.
1. If there are large displacement events in the programme material, enable the DePop
section and raise the sensitivity fader until the largest events are detected and repaired.
2. For clicks, enable that section and raise the sensitivity fader until they are detected and
repaired.
3. Finally if there is crackle left, enable that section and raise its fader to remove the crackle.
Tip: There is necessarily some degree of overlap in the detection circuits of clicks and
crackle. Decreasing the DeClick sensitivity might increase the apparent detection of crackle;
and increasing the DeClick sensitivity might indicate less crackle. Best results are likely if
the two controls are balanced.
