Random Hall Parameters

The Reverberator
RTIM (Reverb Time)

.02 - 60.49s

RTIM sets the reverb time for mid-frequency signals. Because low-frequency reverb time
(BASS) is a multiplier of RTIM, RTIM acts as a master control for the reverb time.

SIZE

4.0 - 39.4M

SIZE sets the rate of buildup of diffusion after the initial period (which is controlled by DIFF).
It also acts as a master control for RTIM and SPREAD. The SIZE control changes a reverb sound
from very large to very small. Generally, you should set the SIZE control to approximate the
size of the acoustic space you are trying to create, before adjusting anything else. The size in
meters is roughly equal to the longest dimension of the space. Moving SIZE while a signal is
present may cause audible transients on critical material.

The apparent size of the space created is actually a combination of the settings of the SIZE,
SHAPE, and SPREAD controls. Small acoustic spaces are characterized by a rapid buildup of
diffusion. However, both small and large spaces frequently have an uneven buildup of initial
reverberation. This uneven buildup is controlled by the SPREAD and SHAPE controls.

SHAPE 0 - 255
SPREAD 0 - 250
SHAPE

and SPREAD work together to control the overall ambience of the reverberation

created by NuVerb. SHAPE determines the contour of the reverberation envelope. With
SHAPE all the way down, reverberation builds explosively, and decays quickly.

As SHAPE is advanced, reverberation builds up more slowly and sustains for the time set by
SPREAD. With SHAPE in the middle, the buildup and sustain of the reverberation envelope
emulates a large concert hall (assuming that SPREAD is at least halfway up, and that SIZE is
suitably large—30 meters or larger.)

SPREAD

works together with SHAPE to control the duration of the initial ambience created

by NuVerb. Low SPREAD settings result in a rapid onset of reverberation at the beginning of
the envelope, with little or no sustain. Higher settings spread out both the buildup and sustain.
