Gain Factor
Figure 100: Gain Factor
Gain Factor defines how much gain is applied to the group slots. Many
harmonic tonal noises have a “1/f” volume profile, where the lower harmonics
are strong and higher harmonics are progressively weaker. The Gain Factor
controls the gain taper of the slots so that the slot gain can parallel the
harmonic strength profile. The base slot always has the specified Slot Gain,
while subsequent slots taper to smaller gains as frequency increases. The
higher the Gain Factor, the more gradual the taper. A Gain Factor of 0.0
produces the most severe taper and means effectively that there are no
harmonics at all. A Gain Factor of 1.0 means that slots have uniform gain at
the Base Slot gain setting.

Upper Limit
Figure 101: Upper Limit
Upper Limit defines how many slots there are in the group. If a harmonic tonal
noise only extends up to a certain frequency, it may be undesirable to slot out
all multiples of the base frequency when only a few are needed. In this case,
set the Upper Limit just above the highest frequency where a slot is desired;
slots will be added up to that limit, and no slots will be added above the limit.

Add Slot
Figure 102: Add Slot Button
Adds a new single slot at the frequency indicated in the Slot Frequency box and
by a marker on the visualization axis. The slot is added with default settings,
and the user is presented with controls to adjust the frequency, width, and gain
of the slot.
