Predelay (C Slider) was originally used to simulate the delay before hearing
reverberation in a large hall. However, in modern reverb program it is used more
for effect. You can use predelay on a vocal reverb to make the word pronunciation
clearer, or on a sidestick reverb, delaying in tempo to the music for those big '80s-
style ballads. You can also leak some non-predelayed reverb using the Predelay Mix
(D Slider) if you want. For this program, I've chosen a Predelay of 32ms with 100%
mix for a splash of reverb.

The High and Low Frequency Damping parameters are on page 3. The damping
parameters interact with the Decay time according to frequency. In a hall with no
high frequency damping, the high frequencies will "sizzle" with a long decay,
especially noticable on "s" syllables and cymbals. With no low frequency damping,
the low frequencies will boom with a long decay, as in a large cement parking
garage. Raising the frequency of the Low damping will cut the decays below that
frequency (like adding bass traps to the hall), and lowering the frequency of the
High Damping will cut the decays above the frequency (like adding drapes and
couches to the hall).
For this room, I'll leave Low Damping off and set my High Damping for 2.14kHz.
Remember that if you set the High Damping higher than the input LPF, it will do
almost nothing. Notice how the apparent decay drops off when you do this, and
that the room starts to sound more natural.
Swirl (C Slider) is an effect which simulates moving walls. Set to a low value, it can
add subtle movement to your reverb sound. Set high, it adds chorusing to the room.
we'll leave it off in this example.

Early Reflections can really add charicter to a program. A shape of 0 with a short
spread can give you the sound of a small room, where a shape with more attack and
a longer spread gives you the sound of a bigger space. The latter example simulates
the sound of a large cave or a castle. Since that's close to the effect I want, we'll split
the differance with a long spread with a quick but audible attack:

Page 4 deals with gating, which we won't use for this example. Just make sure the
Gate parameter (A) is set to OFF and the rest of the settings don't matter.
Now we're ready to go back to page 1, parameters B and C. Bass Boost can be useful
for adding a little warmth to a hall program. By setting the frequency to 237Hz and
the Level to 100, we can add a touch of warmth to our hall program.
