The speed at which the delay elements move is controlled by SPIN. Values of SPIN which are
higher than about 38 can cause audible pitch wobble in very critical material (such as classical
guitar or piano and can also cause noise on pure tones. This noise is not audible in speech,
however, and, for mixed music or speech, values up to 48 will give an improved sound.
WANDER is typically set to about 10ms at larger settings of SIZE. The effect of WANDER is
reduced for small SIZEs.
Creating a Realistic Sound
When you set out to create a sound, the first and most important decision is how big a space
you want. The best way to start is to listen to several presets and choose the one which sounds
closest to what you have in mind. If necessary, use SIZE to make a slightly larger or smaller
sound, as needed.
Next use RTIM to fine-tune the amount of time the reverberation takes to die away at the end
of musical phrases. Actual halls vary a great deal in their actual RTIM values. The setting of
the BASS is also critical in matching the sound of an existing hall. An ideal concert hall would
have a BASS setting of 1.2. It is rare when actual physical spaces exceed 1.5. Many (if not most)
good recording environments have values of BASS of 1.0 or less, so a value of 0.8 could be tried
when attempting to match an existing hall.
There are two additional controls to deal with. SHAPE and SPREAD adjust the effective reverb
time when the music is running. Higher values of SHAPE and SPREAD produce a longer
effective reverb time. Longer effective reverb times give greater spaciousness to the sound.
The NuVerb reverberation effect offers the option of adding early reflections (pre-echoes)
which have been made into diffused clusters of pre-echoes. The density of the cluster is set by
the DIFFUSION control. We recommend that these pre-echoes be used with caution, unless
you are trying to match the sound of the reverberation to a particular location where such
reflections are strong.
