Random Ambience
General Description
The NuVerb Random Hall effects are designed to add a cushion of reverberance to recorded
music, while leaving the clarity of the direct sound unaffected. Random Ambience is different.
It is intended to become a part of the direct sound — to give it both better blend and a definite
position in space. Random Ambience gives warmth, spaciousness and depth to a performance
without coloring the direct sound at all.
Random Ambience generates primarily the strong reflections which appear in the first few
hundred milliseconds of the reverberation process. These early reflections constitute the
primary audible effect, giving you the impression of a hall surrounding you while the music
is playing. To avoid any coloration from these strong reflections, the time delays and
amplitudes are random functions.
Random Ambience is very useful for adding a room sound to recorded music or speech. It is
particularly easy to match a studio recording of dialog to a typical room environment. In music
recording, using Random Ambience is an effective way of realistically adding distance to a
close-miked signal. If an ensemble has been recorded with close-mikes and pan pots, Ambi-
ence can provide the missing blend and depth. The apparent position of the instruments is
preserved in the reverb while the apparent distance is increased. Random Ambience is also
useful in matching a closely miked accent microphone to the overall ambience of a recording.
This allows a soloist to be increased in level without changing the apparent distance. Random
Ambience can be used in a recording situation any time a close-miked sound is undesireable.
Set the SIZE to the desired room size. RLVL adjusts the amplitude of reverberation defined by
RTIM, and can be trimmed to get exactly the effect you need.
To use the effect with a console, it is best to use a stereo send to NuVerb, carefully matching
the panning of the various close-miked sources to their positions in the mix. Leave the MIX
control at 100%. The apparent distance of each source can be controlled by the level of its feed.
