D-Verb (RTAS and AudioSuite)
Digital reverberation processing can simulate the complex natural reflections and echoes that
occur after a sound has been produced. Reverberation can take relatively lifeless mono source
material and create a stereo acoustic environment that gives the source a perceived weight and
depth in a mix. In addition, digital signal processing can be used creatively to produce
reverberation characteristics that do not exist in nature.
The character of reverberation depends on a number of factors. These include proximity to the
sound source, the shape of the space, the absorptivity of the construction material, and the
position of the listener. D-Verb provides control over these reverberation parameters so that
extremely natural sounding reverb effects can be created and applied.
The D-Verb plug-in has the following parameters:
Parameter Description
Input Lets you adjust the input volume of the reverberation.
Mix Lets you adjust the balance between the Dry (source) signal and the Wet (processed) signal,
giving you control over the depth of the effect.
Algorithm Lets you select one of seven reverberation algorithms. Selecting an algorithm changes the preset
provided for it.
• Hall — Good, general-purpose concert hall with a natural character
• Church — Dense, diffuse space simulating a church or cathedral
• Plate — Simulation of the acoustic character of a metal plate–based reverberation, which has
the general effect of thickening the initial sound itself
• Room 1 — Medium-sized, natural, rich-sounding room with an adjustable range from very
small to large
• Room 2 — Smaller, brighter reverberant characteristic than Room 1, with an adjustment
range that extends to very small
• Ambient — Transparent response for adding a sense of space without adding a lot of depth
or density
• Nonlin — Nonlinear reverberation with a natural buildup and an abrupt cutoff similar to a
gate
Size In conjunction with the Algorithm parameter, lets you adjust the overall size of the reverberant
space. There are three sizes: Small, Medium, and Large. The character of the reverberation
changes with each setting (as does the relative value of the Decay parameter).
Diffusion Sets the degree to which initial echo density increases over time. High settings result in high
initial buildup of echo density. Low settings cause low initial buildup. This control interacts with
the Size and Decay parameters to affect the overall reverberation density.
