Chapter 12 Convolution Reverb: Space Designer 171
 Filter parameters: You can further modify the timbre of the Space Designer reverb
using these resonant filter parameters. You can choose from a number of filter
modes, adjust the resonance of the filter, as well as adjust the filter envelope
dynamically over time, as you can with the volume envelope. See “Filter Parameters”
on page 184.
 Synthesized impulse response parameters: If you do enough processing of the original
IR, you may want to synthesize a new IR from your edited parameters. Use these
parameters to adjust the density envelope and other synthesized IR parameters. See
“Synthesizer Impulse Response Parameters” on page 186.
 EQ: For final sound sculpting, Space Designer includes a built-in four-band EQ: two
shelving filters, and two parametric filters. Use these parameters to fine tune the
sound of your reverb to your taste. See “EQ Parameters” on page 188.
Important: In order to convolve audio in real time, Space Designer must first calculate
any parameter adjustments to the impulse response. This requires a moment or two,
following parameter edits, and is indicated by a blue progress bar. During this time you
can continue to adjust the parameter. Once calculation starts, the blue bar is replaced
by a red bar, advising you that calculation is taking place.
Impulse Response Parameters
Space Designer can use either impulse response files or its own synthesized impulse
responses. The circular area to the left of the Envelope and EQ display contains the
impulse response parameters. Here you can determine the Impulse Response mode (IR
Sample mode or Synthesized IR mode), load or create impulse responses, and set the
sample rate.
 IR Sample button: Click to switch Space Designer to the IR Sample mode. The loaded
impulse response sample is used to generate reverberation.
