REVERBS

The Vocalist® Live Pro provides you with the legendary licensed Lexicon Reverbs. Note that
each of the 4 Reverb Types are applied in stereo.
Reverberation (or "reverb" for short) is the complex effect created by the way we perceive
sound in an enclosed space. When sound waves encounter an object or boundary, they don't
just stop. Some of the sound is absorbed by the object, but most of the sound is reflected or
is diffused. In an enclosed space, reverb is dependent on many features of that space, including
the size, shape and the type of materials that line the walls. Even with closed eyes, a listener
can easily tell the difference between a closet, a locker room and a large auditorium. Reverb is
a natural component of the acoustic experience, and most people feel that something is missing
without it.
Reverb Reverb is turned Off or On.

Pre Delay creates an additional time delay between the source signal and the onset of
reverberation. This control is not intended to precisely mimic the time delays in natural
spaces, as the build-up of reverberation is gradual, and the initial time gap is usually rela-
Pre
tively short. For the most natural effect, the Pre Delay values should be set in the range
Delay
of 10-25 milliseconds. However, if a mix is very busy or overly cluttered, increasing the
Pre Delay time may help clarify it, and set each voice apart from each other.
Range: 0ms to 200ms
A Hall Reverb is designed to emulate the acoustics of a concert hall, a
space large enough to contain an orchestra and an audience. Because of
the size and characteristics, Halls are the most natural-sounding reverbs,
designed to remain "behind" the direct sound, adding ambience and
space, but leaving the source unchanged. This effect has a relatively low
initial echo density which builds up gradually over time. Vocal Hall reverb
is specifically tailored for that use and has as lower overall diffusion which
works well with program material that has softer initial transients like a
voice. Vocal Hall reverb is a good choice for giving separate lead and har-
mony voices 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 makes the plate vibrate, causing sounds to appear to be occurring in
a large, open space. The Plates in the Vocalist Live Pro model the sound
of metal plates with high initial diffusion and a relatively bright, colored
sound. Plate reverbs are designed to be heard as part of the music, mel-
lowing and thickening the initial sound.
Room produces an excellent simulation of a very small room which is
useful for dialog and voice-over applications. Room is also practical when
used judiciously for fattening up high energy signals.
Ambience is used to simulate the effect of a small or medium sized room
without noticeable decay.
