• Adds a percentage of processed voices back into the effect input. Feedback can give a waveform an
Feedback
extra echo or reverb effect. A little feedback (less than 10%) can provide extra richness, depending on the delay and
vibrato settings. Higher settings produce more traditional feedback, a loud ringing that can get loud enough to clip
the signal. Sometimes this clipping is a desired effect, as in the Flying Saucers preset, which generates the warbled
sounds of UFOs whizzing around your head.
• Specifies the maximum amount of delay allowed. An important component of chorusing is the intro-
Delay
duction of short delays (often in the 15-35 millisecond range) that vary in duration over time. If the setting is very
small, all the voices start merging into the original, and an unnatural flanging effect might occur. If the setting is too
high, a warbled effect might occur, like a tape being eaten by a cassette deck.
DeClicker
The DeClicker is used to remove unwanted clicks from the audio signal. Clicks often are introduced by bad splices
on film edits, or bad digital edits of the audio footage. Often the DeClicker is very helpful for small pops introduced
by hitting a microphone.
In the Effect Controls panel, Custom Setup for this effect shows Input and Output monitors. The first shows the
input signal with any detected clicks. The second shows the output signal with the clicks removed.
Determines the threshold for the detection and thus determines how much of the signal will be affected.
Threshold
This control ranges from 0 to 100%.
Determines the extent of the reduction of low frequency clicks. These sometimes sound more like a plop
DePlop
than a click. This control ranges from 0 to 100%.
DeCrackler
The Decrackler removes crackling sounds from sources such as 16mm and 35mm film soundtracks, and shellack or
vinyl recordings. The DeCrackler can also mitigate crackles caused by raindrops on windows, bad audio cables, the
proximity of electrical devices to microphone cables, and clip-on microphones rubbing cloth.
In the Effect Controls panel, Custom Setup for this effect shows Input and Output monitors. The first shows the
input signal with any detected crackles. The second shows the output signal with the crackles removed.
Determines the detection level for the crackles. This control ranges from 0 to 100%.
Threshold
Determines the amount by which the crackles will be reduced. This control ranges from 0 to 100%.
Reduction
This meter indicates the efficiency of the DeCrackler. The Threshold dial should be tweaked to get

the maximum value. Please be aware that the maximum will also be reached when the threshold is very low, but at
this point the fundamental audio signal will be harmed.
When selected, this control lets you hear only the sounds that will be removed. When the actual contents
Audition
of the audio can be heard in audition mode, this is a strong indication that the threshold is set too low. If the
threshold is left unadjusted the audio signal will be harmed.
DeEsser effect
The DeEsser removes sibilance and other high frequency "SSS"-type sounds, which are often created when a
narrator or vocalist pronounces the letters "s" and "t." This effect is available for 5.1, stereo, or mono clip.
Specifies the amount of reduction applied to the "SSS" sound. The meter displays the amount of the reduction,
