Space Designer convolution reverb
Logic Pro Space Designer overview
Space Designer is a convolution reverb effect that you can use to place your audio signals
in exceptionally realistic recreations of real-world acoustic environments. Space Designer
generates reverb by convolving, or combining, an audio signal with an impulse response
reverb sample. An impulse response is a recording of reverb characteristics, or more
precisely, a recording of all reflections in a given room following an initial signal spike.
The actual impulse response file is a standard audio file.
To understand how this works, imagine a situation where Space Designer is used on a
vocal track. An impulse response file recorded in an actual opera house is loaded into
Space Designer. This impulse response file is convolved with your vocal track, placing
the singer inside the opera house.
Convolution can be used to place your audio signal inside any space, including a
speaker cabinet, a plastic toy, a cardboard box, and so on. All you need is an impulse
response recording of the space.
In addition to loading impulse responses, Space Designer includes an on-board impulse
response synthesis facility. This enables the creation of completely unique effects,
particularly when the synthesized impulse response doesn’t represent a real space.
Space Designer also offers features such as envelopes, filters, Output EQ, and stereo/
surround balance controls, which provide precise control over the dynamics, timbre,
and length of the reverberation.
Space Designer can operate as a mono, stereo, true stereo (meaning each channel is
processed discretely), or surround effect.
Automation and Space Designer
Space Designer cannot be fully automated—unlike most other Logic Pro plug-ins. This
is because Space Designer needs to reload the impulse response and recalculate the
convolution before audio can be routed through it.
You can, however, record, edit, and play back any movement of the following
Space Designer parameters:
• Stereo X-Over
• Direct Output
• Reverb Output
