General Description
NuVerb incorporates the results of a great deal of research into acoustics and reverberation.
Reverberation, or reflected sound energy, gives recorded music a sense of being performed in
a real acoustic location.
In NuVerb, the SIZE, SPREAD and SHAPE controls allow adjustment of the buildup and decay
of the initial part of the reverberation envelope. SHAPE controls the shape of the envelope,
while SPREAD and SIZE set the time over which this shape is active.
In the Random Hall effect, SIZE acts as a master control for the apparent size of the space being
created by NuVerb. Both SPREAD and RTIM vary linearly with the setting of SIZE. Thus
maximum reverb time and spread require high settings of SIZE. To find an appropriate reverb
sound, start with a preset with a similar sound to what you want to end up with. Simply
varying SIZE is often sufficient to arrive at the exact sound you are seeking.
Once a size has been selected, SPREAD and SHAPE are used to adjust the shape and duration
of the initial reverb envelope, which together provide the major sonic impression of room size.
When SHAPE is at minimum, the reverberation envelope builds up very quickly to a
maximum amplitude, and then dies away quickly at a smooth rate. This envelope is character-
istic of small reverberation chambers and reverberation plates. There are few (if any) size cues
in this envelope, so it is ineffective in creating ambience. With this SHAPE setting, SPREAD has
no effect. The density is set by the size control, and the rate of decay is set by RTIM. This
reverberation envelope is typical of many of the popular digital reverberators of the last few
years.
