REVERBS

Reverberation (or reverb for short) is the complex effect created by the way we perceive sound in an
enclosed space. hen sound waves encounter an object or boundary, they don t just stop. Some of the sound
dependent on many features of that space, including the si e, shape and the type of materials that line the
walls. Even with closed eyes, a listener can easily tell the difference between a cupboard, a loc er room and a
large auditorium. Reverb is a natural component of the acoustic experience, and most people feel that
something is missing without it.

A Hall reverb is designed to emulate the acoustics of a concert hall
and an audience. Because of the si e and characteristics,Halls are the most natural-sounding reverbs, designed to

setting which is necessary to smooth out faster transient signals found in drums and percussion instruments.
In addition to general instrumental and vocal applications, the Hall program is a good choice for giving separate trac s
in a mix the sense of belonging to the same performance.

A Plate reverb is a large, thin sheet of metal suspended upright under tension on springs. Transducers attached to the
plate transmit a signal that ma es the plate vibrate, causing sounds to appear to be occurring in a large, open space.
The Plates in the Vi4 F units model the sound of metal plates with high initial diffusion and a relatively bright, colour-
ed sound. Plate reverbs are designed to be heard as part of the music, mellowing and thic ening the initial sound.
Plate reverbs are often used to enhance popular music, particularly percussion.

Historically, recording studio chambers were oddly shaped rooms with a loudspea er and set of microphones to collect
ambience in various parts of the room. Chamber programs produce even, relatively dimensionless reverberation with
little colour change as sound decays. The initial diffusion is similar to the Hall programs. However, the sense of si e
and space is much less obvious. This characteristic, coupled with the low colour of the decay tail, ma es these pro-
grams useful on a wide range of material - especially the spo en voice, to which Chamber programs add a noticeable
increase in loudness with low colour.
