Compensating for Precision Limiter
The Precision Limiter has a 1.5ms look-ahead window to ensure clipping does
not occur. This look-ahead function results in a slightly larger latency than
other UAD plugins. This is not normally an issue because the Precision Limiter
is designed to be used for program material on the output bus, where latency
is not a consideration. However, if the Precision Limiter is used elsewhere in
the signal chain and the host does not automatically compensate for latency
at that point in the signal chain, it requires slightly more compensation to re-
main perfectly synchronized with other tracks.
Therefore, when using the DelayComp or TrackAdv plugin to manually com-
pensate for the Precision Limiter, enter the Samples value from Table 3 below
(in addition to the appropriate Plugs value) for each instance of Precision Lim-
iter. Since the maximum Samples value in one DelayComp instance is 128,
more than one DelayComp instance will be required (in series) if the sample
rate is 88.2kHz or higher.
Important: Compensating for Precision Limiter is not required if the host ap-
plication supports full plugin delay compensation throughout the entire signal
path, or when it is used only on the outputs. See “Host PDC Implementation”
on page 46.
The compensation value to use depends on the session sample rate. Use the
Table 3 values in DelayComp to compensate for Precision Limiter latency
when using it on track inserts or buses.

Group/Bus
Examples
Situation: You have a song with bass, drums, guitar, and 2 horn tracks. The
session is running at 44.1kHz.You want to maximize the level for the horns so
you put both horn tracks on a group/bus and apply one instance of Precision
Limiter to the horn bus. Result: The horn tracks play late in relation to the other
instrument tracks.
