User Guide

Waves IR-1 software guide page 31
In natural IRs, there is no distinct delineation between ER and TR; the definition of where
the best ER/TR-X crossover point is subjective. The user is allowed to modify the
automatic decision of the plugin by using the ER/TR-X control, in milliseconds, relative to
the automatic crossover point.
In IRs where the direct signal is not found, the Direct Gain and Predelay become
disabled.
If the direct signal has already been removed by the user before importing an IR, or if the
source of the IR is not acoustically natural, and the direct path is not a part of it, then the
plugin may detect the first early-reflection as direct.
In that case, the user should make sure that the Direct On/Off button is On. In some cases,
if the IR is too short or if its behavior is not acoustically natural, the plugin may fail to detect
the Direct, ER, or Tail as separate parts.
This is typical of small rooms or spaces with a reflective floor. The direct signal and the ER
cannot be separated, theoretically, since the first ER arrives before the direct path response
terminates. They appear as mixed in the IR. In such cases the plugin presents the best
separation, possible, but the direct would appear to include some reflections.
CROSSTALK : Range: 0.0 to 100.0; Default 0.0
This control is only available in the "Efficient" components.
This controls how much Crosstalk is allowed between the IR-series’ input channels. When
the Crosstalk is 0.0 the process is multi-mono, convolving left to left and right to right.
When Crosstalk is at 100.0, the plugin will convolve a summed stereo input. The dry signal
is not affected, so the reverb will have elements from the left channel in the reverb of the
right channel and vice versa.
