Configuring Pro Tools LE
Pro Tools System Settings
Pro Tools LE allows you to adjust the perfor-
mance of your system by changing system set-
tings that affect its capacity for processing, play-
back, and recording.
In most cases, the default settings for your sys-
tem 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) con-
trols the size of the hardware cache used to han-
dle host processing tasks such as Real-Time Au-
dioSuite (RTAS) plug-ins. The H/W Buffer setting
can also be used to manage monitoring latency.
◆ Lower Hardware Buffer Size reduce monitor-
ing latency, and are useful when you are record-
ing live input.
◆ Higher Hardware Buffer Size settings allow for
more audio processing and effects, and are use-
ful when you are mixing and using more RTAS
plug-ins on your system.
In addition to causing slower screen re-
sponse and monitoring latency, higher
Hardware Buffer Size settings can affect the
accuracy of plug-in automation, mute data,
and timing for MIDI tracks.
