Reverb and Early Reflections
100: Overb
The O-Verb features a high-quality, diffusion-based
reverb core. In addition to setting the size of the room,
you can model its shape and materials by adjusting the
diffusion characteristics of both the initial reflections
and the main reverberant wash, and via separate
controls for the high, mid, and low decay times. The O-
Verb also includes randomization, for richer and
smoother reverb timbres.
Pre EQ
There are two fully parametric bands of peaking EQ,
for adjusting the reverb timbre. These affect only the
reverb, and not the dry signal. Both bands have
identical parameters.
Trim [0…100]
Sets the EQ input level.
Band 1
Band1 [Check-box]
Switches the first band of EQ band on and off.
Fc [Hz] [200…20.00k]
Sets the center frequency of Band 1.
Q [0.5…10.0]
Sets the bandwidth of Band 1.
Gain [dB] [–18.0…+18.0]
Sets the gain of Band 1.
Band 2
Band 2 has the same parameters as Band 1, above.
Rolloff
Rolloff [0…100]
This controls a lowpass filter on the output of the
effect. Settings around 6-8kHz are good for producing
a warm, smooth sound.
REVERB
Pre Delay [msec] [0…1360]
Sets the delay time from the dry sound.
Diffusion1 [0…100]
Diffusion 1 and 2 soften the sound before it enters the
reverb core, shaping the timbre of the initial reflections.
Setting both diffusers to around 50 generally produces
sufficient diffusion for smooth reverbs; extremely high
levels may cause ringing.
Some source material, such as vocals, may also benefit
from lower settings of diffusion, allowing for more
discrete echoes.
Diffusion1 and Diffusion2 differ in how the
reflections are spaced, and the balance between these
two parameters will vary the character of the reverb.
Diffusion2 [0…100]
This is the second diffuser for the initial reflections. For
more information, see “Diffusion1,” above.
Size [5…100]
Sets the size of the space.
Time [0…100]
This sets the main reverberation time. The Damping
and (bass) Gain parameters, below, let you adjust the
decay times separately for the high and low
frequencies, respectively.
Diffusion [0…100]
This sets the density of reflections within the main
reverb. Low settings will produce more discrete
echoes, and high settings will produce a smoother
reverb. Extremely high settings may cause ringing.
Reverb Size, Time, and Diffusion
Damping [0…100]
This sets the cutoff of the high-frequency damping
filter. If Damping is set to 100, the high frequencies will
decay at the same rate as the low frequencies; at 0, the
high frequencies will decay almost instantly.
