Chapter 12 Convolution Reverb: Space Designer 187
 End Level: Sets the density of the reverb tail. If you select an End Level value that is
too low, the reverb tail will sound grainy. You may also find that the stereo spectrum
is affected by lower values.
 Reflection Shape: Determines the steepness (shape) of the early reflection clusters as
they bounce off the walls, ceiling, and furnishings of the virtual space. Small values
result in clusters with a sharp contour, and large values result in an exponential slope
and a smoother sound. This is handy when recreating rooms constructed of different
materials. Reflection Shape, in conjunction with suitable settings for the envelopes,
density, and early reflection will assist you in creating rooms of almost any shape and
material.
Spread Parameters
The Spread and Xover knobs adjust the perceived stereo or surround width of a
synthesized impulse response. While the Spread and Xover knobs are placed among
the global parameters, they only function in Synthesized IR mode.
Note: As these parameters adjust stereo or surround processing, they have no impact
when using the Space Designer as a mono plug-in.
Spread extends the stereo or surround base to frequencies that fall below the
frequency determined by the Xover (crossover) parameter.
At a Spread value of 0, no stereo or surround information is added (although the
inherent stereo or surround information of a signal and reverb will be retained). At a
value of 100, the left and right channel divergence is at its maximum.
The Xover parameter is set in Hertz. Any synthesized impulse response that falls below
this threshold value will be processed by adjustments over 0 for the Spread parameter.
The effect enhances the perceived width of the signal, without losing the directional
information of the input signal normally found in the higher frequency range. Low
frequencies are spread to the sides, reducing the amount of low frequency content in
the center—allowing the reverb to nicely wrap around the mix.
