The UAD device drivers are the low-level system software files that instruct the
host computer system on how to communicate with the UAD device(s). The
UAD drivers are loaded during system startup so the UAD devices are ready
to be used when the plug-in host application is launched.

In addition to instructing the OS on how to control the UAD hardware, the
driver acts as a software “middleman” between the host application and the
UAD hardware. The host application uses the driver to route UAD signals in
the DAW.

Each UAD device family (UAD-2 or UAD-1) has its own set of drivers. One or
both are specified during UAD software installation, depending on which de-
vice type(s) you have installed.

UAD Buffers and Latency

The UAD drivers use “buffers” to shuttle audio signals to and from the device.
This means the digital data is transferred in small batches instead of continu-
ously. Buffering induces a very small audio latency (delay) that is inherent in
most digital audio systems and can be detected in certain situations.

UAD latency is managed automatically by most host applications and can be
reduced to undetectable levels in the UAD-2 (see

“LiveTrack Mode” on

page 89

). Latency and buffers are discussed in greater detail in

Chapter 9,

“UAD Delay Compensation.”
