PlatinumVerb reverb parameters
PlatinumVerb provides the following reverb parameters.
PlatinumVerb reverb parameters
•
Initial Delay slider and eld: Drag to set the time between the original signal and the diuse
reverb tail.
•
Spread slider and eld: Drag to control the width of the reverb’s stereo image. At 0%, the eect
generates a monaural reverb. At 200%, the stereo base is articially expanded.
•
Crossover slider and eld: Drag to set the frequency used to split the input signal into two
frequency bands, for separate processing.
•
Low Ratio slider and eld: Drag to determine the relative reverb times of the bass and high
frequency 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 eld: Drag to set 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 eects.
•
High Cut slider and eld: Drag to lter frequencies above the set value from the reverb signal.
Uneven or absorbent surfaces—wallpaper, wood paneling, carpets, and so on, tend to reect
lower frequencies better than higher frequencies. The High Cut lter replicates this eect. If
you set the High Cut lter so that it is wide open (maximum value), the reverb sounds as if it is
reecting o stone or glass.
•
Density slider and eld: Drag to set the density of the diuse 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 x by reducing the Density slider value. Conversely, if you select a
Density value that is too low, the reverb tail sounds grainy.
•
Diusion slider and eld: Drag to set the diusion of the reverb tail. High Diusion values
represent a regular density, with few alterations in level, times, and panorama position over
the course of the diuse reverb signal. Low Diusion values result in the reection density
becoming irregular and grainy. This also aects the stereo spectrum. As with Density, nd the
best balance for the signal.
•
Reverb Time slider and eld: Drag to determine the reverb time of the high frequency 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.
