UAD Powered Plug-Ins Manual - 210 - Chapter 17: DreamVerb
Materials Menus DreamVerb lets you specify two room materials, which
can be blended to create a hybrid of absorption and re-
flection properties. The first and second room material
each has its own menu. The available materials are the
same for each of the two materials menus.
The first material is displayed in the lower left area of the
Materials panel, and the second material is displayed in
the lower right area.
To select the first or second material, click its material
pop-up selector menu to view the available materials,
then drag to the desired material and release.
For a discussion of the various materials, see “About the
Materials” on page 489 .
In addition to the “perfect” materials marked with a K,
DreamVerb provides “J” materials that are not found in
RealVerb Pro. These perform the inverse of the “K” mate-
rials. The materials marked with a J preferentially absorb
low frequencies; they give the selected decay time at
high frequencies, and a much shorter decay time at low
frequencies.
Air Density
Menu
DreamVerb allows you to specify the density of the air in
the reverberant space with this menu, enabling another
dimension of sonic control.
The more dense the air is, the more it
absorbs high frequencies. At the top
of the Air Density menu is Ideal Gas,
where no frequencies are absorbed.
The air quality increases in density
with each selection as you go down
the menu.
Inverse Air and Inverse Thick Fog ab-
sorb more low frequencies instead of
high frequencies.
