Setting Impulse Response Lengths in Space Designer
You can use the Length parameter to set the length of the impulse response—sampled
Space Designer Convolution Reverb
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 you are 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.
