UAD-2 DSP Settings
Overview
Without UAD plug-ins, overloading the host computer system with native (host CPU 
based) plug-ins can cause audio dropouts and other system issues. Some DAWs, for 
example, provide a switch that allows you to trade latency for stability when the system 
is overloaded. Similarly, the UAD DSP load cannot exceed 100% without unpredictable 
behavior.
With the Limit DSP Load feature, the UAD DSP can also be limited so the load cannot 
exceed 100%, thereby increasing overall system stability in high load situations. With 
very heavy UAD loads, DSP load limiting may also improve host CPU performance.
There are many variables that affect DSP load (sample rate, I/O buffer size, parameter 
values, mono/stereo, automation, host system performance, etc). Although these 
variables are taken into account, the resulting measurement cannot be absolutely 
accurate due to variations in system configurations, including computer bus loading, 
which is impossible to measure. 
Systems that are heavily loaded due to the presence of other devices or suboptimal 
configurations may cause additional DSP loading that cannot be measured by the UAD 
plug-in load calculator. The DSP load limit should be reduced in this case.
It is possible for certain (atypical) conditions to be met where another UAD plug-in can’t 
be added, even when the UAD Meter says you should have DSP available when compared 
to the DSP Load Limit value.
Note: When Limit DSP Load is enabled and the DSP load limit is exceeded when 
instantiating a new UAD plug-in, an overload message will appear and DISABLED 
will be displayed in the plug-in’s UAD Toolbar. In this case, even though the UAD 
plug-in loads, it will not process audio.
Limit DSP Load
This setting determines the maximum UAD DSP load. If performance issues such as 
overloads, dropouts, stuttering, and/or other artifacts persist, change the UAD DSP load 
value by clicking the triangles to the right of the percentage display or entering a value 
directly with text entry.
Note: UAD-2 DSP load limiting is always on. 100% (the default value) is the 
maximum available setting.
