Effects Reference

138 Chapter 11 Convolution Reverb: Space Designer
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 and allowing the reverb to nicely wrap around the mix.
EQ Parameters
Space Designer features a four-band EQ comprised of two parametric mid-bands plus
two shelving filters (one low shelving filter and one high shelving filter).
