Space Designer Convolution
Reverb
Space Designer is a convolution reverb effect. You can use it 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 (IR) reverb sample. An impulse response is a recording of a room’s
reverb characteristics or, to be more precise, 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 IR recorded in an actual opera house is loaded into Space Designer. This
IR 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 IR recording of the
space.
In addition to loading impulse responses, Space Designer includes an on-board impulse
response synthesis facility. This enables you to create completely unique effects, particularly
when the synthesized IR doesn’t represent a real space.
Space Designer also offers features such as envelopes, filters, 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.
