Buffer Size
You may select from the following buffer sizes
(depending on your Pro Tools hardware):
• 64 samples
• 128 samples
• 256 samples
• 512 samples
• 1024 samples
• 2048 samples
Small buffers have the advantage of low
latency in the record monitor path. (Latency is
the time delay between a signal entering the
audio inputs and leaving the outputs during
recording.)
Larger buffers have the advantage of making
the ASIO Driver more immune to audio dropouts
during playback and recording.
In some ASIO-compatible audio programs, per-
forming various tasks will interrupt the ASIO
Driver and may result in clicks and pops in au-
dio playback or recording. Choosing medium or
large buffers (such as 256, 512, or 1024) can help
alleviate this problem.
