Threshold
Threshold controls minimum level at which the dynamic gain actually starts working.
Level gain
Level gain controls gain applied on the detector, which can be used for example when the input level is too low, so that
dynamic processing becomes negligible.
Link channels
Link channels controls how much the signal level for each channel is controlled by the other channels. With 0% the link is
disabled and each channel is not affected by other channels at all. This is suitable to ballance stereo channels, for example.
With 100% the link is enabled and all channels are controlled by levels of all channels equally, therefore the processor will
apply the same amount of processing on all channels. This is default in most cases as it preserves levels between channels
for example.
Mode
Mode controls the way the band reacts on input signal. It has no meaning if the dynamic gain is 0dB.
Filtered compensated mode is default and it means that the source for measuring input level is filtered signal with
additional compensation. For example, when using a low-shelf filter, the signal is low-passed with a filter with the same
settings as the low-shelf, therefore the low-shelf filter is affected by the signal the low-shelf is actually amplifying or
attenuating. Since low-passed signal with cut-off at 100Hz has usually much lower level than the one filtered with cut-off at
10kHz, additional compensation is performed to diminish these differences.
Filtered mode is similar, but the compensation is not performed. This may be advantageous for audio materials not
containing the full spectrum, e.g. bass line, where the compensation may make things complicated.
Entire spectrum mode is the simplest - it simply takes the input signal without any further processing. This may be useful
for example to attenuate selected frequencies when the input level gets too high.

Threshold
Threshold controls minimum level at which the dynamic gain actually starts working.
Harmonics panel
Harmonics panel contains parameters of harmonics - cloned bands created at defined higher frequencies. This is often
useful to remove natural noises, which usually bring some harmonics with them etc.
Linear button
Linear button enables the linear harmonics spacing. When the band frequency is say 100Hz, then in the default
logarithmic mode the harmonics are 200Hz, 400Hz, 800Hz etc. This is suitable, because the filters themselves are
logarithmic, however harmonics generated by physical instruments are not spaced this way, but rather 200Hz, 300Hz,
400Hz, 500Hz etc. In linear mode the harmonics work this way, but note that then there is only a limited set of harmonics
and Q is modified to approximate a reasonable behaviour, which is not always possible.
Depth
Depth defines gain of the created harmonics. With maximum depth, all harmonics will have the same gain as the original
band. Lower value makes higher harmonics have lower gain. Negative depth may even make one have positive and the
other negative gain and is particulary useful for creative effects.
