174 Chapter 12 Convolution Reverb: Space Designer
Similar adjustments can be made while running in Synthesized IR mode. Most typical
reverb sounds don’t feature an excessive amount of high frequency content. If you
were running at 96 kHz, you would need to make use of some deep lowpass filtering to
obtain the mellow frequency response characteristics of many reverb sounds. As a
different approach, you are better served to first reduce the high frequencies by 1/2 or
even 1/4 using the Sample Rate slider, and then apply the lowpass filter. This conserves
a considerable amount of CPU power.
Setting the Length of the Impulse Response
You can use the Length parameter to set the length of the impulse response (sampled
or synthesized).
All envelopes are automatically calculated as a percentage of the overall length, which
means that if this parameter is altered, your envelope curves will stretch or shrink to fit,
saving you time and effort.
When using an impulse response file, the Length parameter value cannot exceed the
length of the actual impulse response sample. Longer impulse responses (sampled or
synthesized) place a higher strain on the CPU.
Global Parameters
Space Designer’s Envelope and EQ display contains most of Space Designer’s interface
elements that change to reflect the current parameter group you are adjusting. The
global parameters, spread throughout the interface around and below the Envelope
and EQ display, remain constant. These parameters can be divided by the relief
graphics of the interface.
The upper (raised) section of Space Designer contains the following global parameters:
