INTRODUCTION to 5.1 Reverbs
These new structures introduce surround ambience to the line of Eventide effects processors.
A description of the algorithms and their parameters functions is your first step to learning the basic of
these powerful tools. We have provided slightly different versions of these algorithms to give the best
results both at 48 and 96KHz sampling frequencies.

Stereo or Surround ambience and reverbs in digital processors are generally to be considered a
combination of two main processes:
Ÿ Early Reflection delays and diffusers
Ÿ Reverberation

In depth:
Early Reflections are very short delays that simulate the reflections of walls, floor and ceiling of a
specific environment. Often they are matched to filters to recreate the tonal qualities of the different
materials of which these surfaces are made.

materials of which these surfaces are made.
Diffusers are even shorter delays networks that create a dense field of repeats. This cluster of small
delays simulates the build-up in density of the first echoes. A high setting of Diffusion will result in a
dense build-up, with smeared delays. A lower setting will provide more distinct delays. Diffusion
directly controls all the Diffuser internal delay feedbacks. This parameter is affected by the Diffusers
Size parameter, which scales up or down all its internal delays times.

A low Size and high Diffusion settings will provide nice small environments with dense diffusion,
while the inverse scenario would better simulate huge spaces.
while the inverse scenario would better simulate huge spaces.
A good starting point in creating your spaces is to first adjust Size and Diffusion as they will define
the space more strongly than the other parameters. Early Reflections then define the position and
reflective qualities of the space and will shape it. Tweaking the hicut filters will provide a further
nice touch to your work. Last, adjust your reverb decay and filters, in search of the next great verb!

We have created 2 different I/O structures:
Ÿ 2_5.1 Diffusers or Reverbs
Ÿ 5.1 Diffusers or Reverbs
Ÿ 5.1 Diffusers or Reverbs
The difference is that version 2_5.1 creates a surround ambience from a stereo (2 inputs) audio
source, while the 5.1 version is a full blown 6 inputs/outputs structure, to be used with audio sources
in this format.
