This can be useful for eliminating level peaks at the beginning of the impulse response<br />

sample. Its use also affords a number of creative options, particularly wh<strong>en</strong> combined<br />

with the Reverse function (see Using Space Designer’s Button Bar).<br />

Note: The IR Start parameter is not available or required in Synthesized IR mode because,<br />

by design, the L<strong>en</strong>gth parameter provides id<strong>en</strong>tical functionality.<br />

Using Space Designer’s Spread Parameters<br />

The Spread and Xover knobs <strong>en</strong>hance the perceived width of the signal, without losing<br />

the directional information of the input signal normally found in the higher frequ<strong>en</strong>cy<br />

range. Low frequ<strong>en</strong>cies are spread to the sides, reducing the amount of low frequ<strong>en</strong>cy<br />

cont<strong>en</strong>t in the c<strong>en</strong>ter—allowing the reverb to nicely wrap around the mix. The Spread<br />

and Xover knobs function only in Synthesized IR mode.<br />

Note: As these parameters adjust stereo or surround processing, they have no impact<br />

wh<strong>en</strong> you use the Space Designer as a mono plug-in.<br />

• Spread knob and field: Ext<strong>en</strong>ds the stereo or surround base to frequ<strong>en</strong>cies that fall below<br />

the frequ<strong>en</strong>cy determined by the Xover (crossover) parameter.<br />

• At a Spread value of 0.00, no stereo or surround information is added (although the<br />

inher<strong>en</strong>t stereo or surround information of the source signal and reverb are retained).<br />

• At a value of 1.00, the left and right channel diverg<strong>en</strong>ce is at its maximum.<br />

• Xover knob and field: Sets the crossover frequ<strong>en</strong>cy in Hertz. Any synthesized impulse<br />

response frequ<strong>en</strong>cy that falls below this value will be affected by the Spread parameter<br />

(at values over 0).<br />

Automating Space Designer<br />

Space Designer cannot be fully automated—unlike most other <strong>Soundtrack</strong> <strong>Pro</strong> plug-ins,<br />

which can be. This is because Space Designer needs to reload the impulse response and<br />

recalculate the convolution before audio can be routed through it.<br />
