Latency Compensation
The complex calculations made by Space Designer take time. This time results in a
processing latency, or delay, between the direct (input) signal, and the processed
(output) signal. The Latency Compensation button determines how Space Designer
delays the direct signal in relation to the processed signal.
Space Designer’s processing latency is 128 samples at 44.1 kHz, and doubles at each
lower sample rate division. For example, if you set Space Designer’s Sample Rate slider
to “/2” the processing latency increases to 256 samples. The processing latency does
not increase in surround mode or with higher sample rates than 44.1 kHz.
When activated, this parameter delays the direct signal (in the Output section) to
match the processing delay of the effect signal. This is not related to latency
compensation in the host application—this compensation occurs within
Space Designer and applies only to Space Designer.
Rev Vol Compensation
Rev Vol Compensation (Reverb Volume Compensation) attempts to match the
perceived (not actual) volume differences of impulse response files.
It is switched on by default and should generally be left in this mode, although you
may find that it isn’t successful with all types of impulse responses. In such situations,
switch it off and adjust the input and output levels accordingly.
Definition
The Definition parameter appears in the definition area at the bottom of the Envelope
and EQ display.
Calculating every precise detail of an impulse response derived reverb uses significant
CPU power. The Definition parameter emulates the diffusion of natural reverb patterns
while at the same time reducing Space Designer’s CPU consumption.
