Chapter 4: Configuring Your Pro Tools System 27
In most cases, the default settings for your system provide optimum performance, but you
may want to adjust them to accommodate large or processing-intensive Pro Tools sessions.
Hardware Buffer Size
The Hardware Buffer Size (H/W Buffer Size) controls the size of the buffer used to handle host
processing tasks such as Real-Time AudioSuite
™
(RTAS) plug-ins. The H/W Buffer setting can
also be used to manage monitoring latency.
 Lower Hardware Buffer Size settings reduce monitoring latency, and are useful when you are
recording live input.
 Higher Hardware Buffer Size settings allow for more audio processing and effects, and are
useful when you are mixing and using more RTAS plug-ins.

In addition to causing slower screen response and monitoring latency, higher Hardware Buffer
Size settings can increase the latency caused by RTAS plug-ins, and affect the accuracy of plug-
in automation, mute data, and MIDI track timing.
