Phase Adjust
90°/180°
This switch determines the range of the Phase Adjust parameter. This is useful
when finer Phase Adjust resolution is desired.
When the switch is disengaged, the Phase Adjust range is 180°. When the
switch is engaged (darker), the Phase Adjust range is 90°.
Phase Center
Lo/Hi
This switch sets the range of frequency emphasis. When the switch is disen-
gaged (lighter), the Phase Center range is Hi. When the switch is engaged
(darker), the Phase Center range is Lo.
Note:
Use of the 90°/180° and Lo/Hi parameters are typically used for in-
dividual tone signals such as a kick drum or toms as opposed to program ma-
terial.
Power
This switch disables the plug-in. When the switch is disengaged, the plug-in is
bypassed. When the switch is engaged (darker), the plug-in is active and the
green LED is illuminated.
Little Labs IBP Latency
The Little Labs IBP uses an internal upsampling technique. This upsampling re-
sults in a slightly larger latency than other UAD plug-ins. See
Upsampled Plug-Ins” on page 108
Note:
Compensating for Little Labs IBP is not required if the host application
supports full plug-in delay compensation throughout the signal path, or when
it is used only on the outputs. See
“Host PDC Implementation” on page 101

An interesting (and highly technical) article named “Allpass Filters” about
phase shifting with allpass filters can be found in the November 2008 “Ask
the Doctors” section of our online WebZine:
