D-Verb Parameters
The D-Verb plug-in has the following parameters:
Input Level
Allows you to adjust the input volume of the reverberation.
Mix
Allows you to adjust the balance between the Dry (source) signal and the Wet (processed) signal, giving you control over the depth of the effect.
Algorithm
Allows you to 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
  Roomá1 — Medium-sized, natural, rich-sounding room that can be effectively varied in size between very small and large
  Roomá2 — Smaller, brighter reverberant characteristic than Roomá1, with a useful adjustment range that extends to very small
  Ambient — Transparent response useful 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, allows you to 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.
Decay
Controls the rate at which the reverberation decays after the original direct signal stops. The value of the Decay parameter is affected by the Size and Algorithm parameters. This parameter can be set to infinity on most algorithms for infinite reverberation times.
Pre-Delay
Allows you to determine the amount of time that elapses between the original audio event and the onset of reverberation.
Hi Freq Cut
Controls the decay characteristic of the high frequency components of the reverberation. It acts in conjunction with the LPáFilter control to create the overall high frequency contour of the reverberation.
LP Filter
Controls the overall high frequency content of the reverberation by allowing you to set the frequency above which a 6-dB-per-octave filter attenuates the processed signal.
