PlatinumVerb Reverb Parameters

The PlatinumVerb offers the following Reverb parameters:

Initial Delay slider and field: Sets the time between the original signal and the diffuse

reverb tail.

Spread slider and field: Controls the stereo image of the reverb. At 0%, the effect

generates a monaural reverb. At 200%, the stereo base is artificially expanded.

Crossover slider and field: Defines the frequency at which the input signal is split into

two frequency bands, for separate processing.

Low Ratio slider and field: Determines the relative reverb times of the bass and high

bands. It is expressed as a percentage. At 100%, the reverb time of the two bands is
identical. At values below 100%, the reverb time of frequencies below the crossover
frequency is shorter. At values greater than 100%, the reverb time for low frequencies
is longer.

Low Freq Level slider and field: Sets the level of the low frequency reverb signal. At 0 dB,

the volume of the two bands is equal. In most mixes, you should set a lower level for
the low frequency reverb signal. This enables you to boost the bass level of the incoming
signal, making it sound punchier. This also helps to counteract bottom-end masking

High Cut slider and field: Frequencies above the set value are filtered from the reverb

signal. Uneven or absorbent surfaces—wallpaper, wood paneling, carpets, and so
on—tend to reflect lower frequencies better than higher frequencies. The High Cut
filter replicates this effect. If you set the High Cut filter so that it is wide open (maximum
value), the reverb will sound as if it is reflecting off stone or glass.

Density slider and field: Controls the density of the diffuse reverb tail. Ordinarily you

want the signal to be as dense as possible. In rare instances, however, a high Density
value can color the sound, which you can fix by reducing the Density slider value.
Conversely, if you select a Density value that is too low, the reverb tail will sound grainy.

Diffusion slider and field: Sets the diffusion of the reverb tail. High Diffusion values

represent a regular density, with few alterations in level, times, and panorama position
over the course of the diffuse reverb signal. Low Diffusion values result in the reflection
density becoming irregular and grainy. This also affects the stereo spectrum. As with
Density, find the best balance for the signal.

Reverb Time slider and field: Determines the reverb time of the high band. Most natural

rooms have a reverb time somewhere in the range of 1 to 3 seconds. This time is reduced
by absorbent surfaces, such as carpet and curtains, and soft or dense furnishings, such
as sofas, armchairs, cupboards, and tables. Large empty halls or churches have reverb
times of up to 8 seconds, with some cavernous or cathedral-like venues extending
beyond that.
