click.
Each section provides a Threshold control. This control is used to adjust a threshold level
within the excitation profile to capture an event. If a peak on the excitation profile is below
the threshold, it will not be registered as an event to be repaired. If a peak breaches the
threshold line, then it is registered as a detected event and can be repaired. When you
touch the Threshold control, by default the excitation profile is displayed visually on the
graph. Usually there is a background level of “noise” at the bottom with the occasional
peak lifting above the background.
You can imagine a click as a triangular shaped peak in the excitation profile, wider at the
bottom and tapering to a point at the top. Keeping this in mind, you have two potential
strategies for detecting and repairing a click.
Excitation Profiles
The first is to lower the threshold in the excitation profile until it is just above the noise floor,
near the base of the triangle. (You can do this either with the Threshold knob, or drag the
threshold line on the graph itself.) This means that the true width of the event is more
likely to be found because the threshold is further down the triangle at the base.
The problem with this approach is that now many events are registered for potential repair.
As the Sensitivity setting is reduced, more and more detected events are rejected and
discarded, starting with the smallest. Thus a low sensitivity means only the largest of the
detected events go forwards to the repair section.
Note:
The Threshold control determines how many events are detected, and the Sensitivity
control determines how many of those detected events go on to be repaired.
The best setting for the Threshold slider is to put it where the threshold line on the
excitation profile is just above the noise floor, and to lower the Sensitivity slider until the
required number of repairs are occurring.
The other approach is to lower the Threshold until it is just under the top of the peaks.
With Sensitivity at maximum, you are then only correcting the events that breach the
