The DePop section can detect events from 10ms down to 1ms. However, it is best to adjust the
DePop Threshold and Sensitivity to ensure that the fewest repairs are done in this section. Use a
low DePop Threshold and a minimum of Sensitivity to achieve this.
If possible, use the DeClicker section to capture the longest and widest of the clicks. Again use a
low DeClick Threshold and a minimum of Sensitivity to achieve this.

Output Panel
The listen section of the Output Panel contains an option to listen to the difference between the
input and the processed output. This is labeled “Diff”. This is particularly useful in this plug-in
for hearing what has been repaired, and for listening to the quality of the repairs without being
distracted by the audio material. You can also listen for breakthrough of audio on the pops,
meaning that the repair is too wide (you need to raise the DePop Threshold a bit). You can listen
for a constant scratching sound, which means that the DeCrackle section may be doing too many
repairs, particularly if you can’t hear that scratching sound in the original. You can listen to make
sure that the sound of the clicks is as close as possible to the sound of the clicks in the original. If
they are brighter, it may mean that the DeClick Threshold slider needs to go lower to capture the
true width of the clicks.

The Events Graph
The events graph is an important visual display, showing events as they are being detected. The
events are shown with duration along the X-axis and amplitude/energy along the Y-axis. It is
worthwhile playing with the Threshold and Sensitivity controls to see their effect on the number
of events that are detected, and at what level and width they are displayed on the event graph.
For example, you will notice that as you bring the Threshold lower, not only are more events
detected, but the events tend to move to the left, meaning the events are being detected as longer
duration. Then as you move the Sensitivity down, you will notice that the smallest events
disappear first, leaving the largest events.
The graph shows green bubbles (DePop), blue bubbles (DeClick) and white bubbles
(DeCrackle). The size of the bubbles indicates how loud they are, as does their height above the
horizontal axis. Each section has an IN button, and if you disable a section using the IN button,
their bubbles are displayed as Red, meaning these events have been detected but not repaired.
