UAD Powered Plug-Ins Manual - 60 - Using UAD Powered Plug-Ins
Important: Compensating for Precision Multiband latency is not required if
the host application supports full plugin delay compensation throughout the
entire signal path, or when it is used only on the outputs. See “Host PDC Im-
plementation” on page 50.
The Precision Multiband latency depends on the session sample rate. Latency
values are listed in Table 6 below.
Because manually compensating for Precision Multiband latency in hosts that
don’t support full plugin delay compensation can be complicated, to avoid
timing errors in these hosts we generally recommend using Precision Multi-
band only on outputs, so no manual compensation is required.
The Formula To manually compensate for Precision Multiband latency when used on
groups/buses in hosts that don’t support full PDC, use the following formula:
L1 ÷ L2 = UAD DelayComp(s) value
Where “L1” is the Precision Multiband latency from Table 6, and “L2” is the
latency from the UAD Meter System Information window (note that at least
one UAD plugin must be running in the host to obtain a valid value).
This formula will arrive at the DelayComp Plugs parameter value (whole num-
ber result), or Plugs plus Samples value (non-whole number result) needed for
compensation. Since the maximum Plugs/Samples value in one DelayComp
instance is 10/128, more than one DelayComp instance will be required (in
series) if the Plugs/Samples value exceeds 10/128, which can happen at
lower buffer sizes and/or higher sample rates.
