I/O Drivers
The audio interface is a hardware device that requires a software device
driver for the host computer OS. In addition to instructing the OS on how to
control the interface hardware, the driver acts as a software "middleman" be-
tween the host application and the I/O ports. The host application uses the
driver to access the I/O for signal routings.
I/O Buffers and Latency
Like the UAD device, audio interface driver also uses "buffers" to shuttle audio
signals to and from the I/O (see
Smaller I/O buffer settings produce lower latencies which is useful when mon-
itoring tracks while recording performances, but usually results in a higher
host computer CPU load since the system has to work harder transferring
data. Latency and buffers are discussed in greater detail in
Delay Compensation."
