6 Equalisation
Equalisation of the reverb signal contribution is included in this comprehensive plug-in to
effect changes in the overall character of the simulation, either in response to artistic need
or to enhance the realism of real space simulations.
Almost all real environments exhibit complex frequency response characteristics that are
generated by the reflection timing of the room spaces and objects within the area. The
actual perceived frequency response is highly dependent on the location of the sound
sources and the position of the listener within the sound space.
A large part of the most complex frequency response character is generated by the Early
Reflections processing within the reverb application, but because simulation models have
a reduced quantity of reflection nodes in comparison to real spaces, much of the overall
resonance and tonal character may be absent from the total simulation.
While the clean, unobtrusive nature and reduced tonal interference of simulated reverb
often blends more effectively in music production, post-production and Foley situations
often require an accentuated realism, and much of this is provided by the overall
frequency character of the simulated spaces. Indeed this partially explains the success of
convolution reverbs in the post-production field.
All of the EQ setup examples contained in the Post-production category (see below) are
examples of combinational reverbs that use equalisation to enhance the realism of spaces
by providing the resonances and response aberrations one would associate with those
spaces.
