Figure 3-2: Access the 'Host Buffer Size' and 'Host Safety Offset'
settings in the web app Device tab for your MOTU interface.
Be careful with very small buffer sizes, as they can
cause performance issues from your host software
or PC.
☛
At sea level, audio travels approximately one
foot (30 cm) per millisecond. A latency of ten
milliseconds is about the same as being ten feet
(three meters) from an audio source.
Host Safety Offset
When connected to a Windows host, the Host
Safety Offset menu (Figure 3-2) also becomes
available. This setting allows you to fine tune host
latency. Larger offsets allow the driver more time to
process audio as it transfers to and from the
hardware. Lower settings produce lower latency,
but if you go too low, your host software may
experience performance issues. Generally
speaking, 48 samples should serve as a good
baseline setting. You can then experiment with
lower settings from there. Be mindful, however,
when reducing the safety offset, as this parameter
can have a significant impact on your computer
system's performance.
MOTU DISCOVERY APP
The MOTU Discovery app (found in the Mac
menu bar or Windows taskbar) locates all MOTU
AVB interfaces connected to the computer, either
directly through USB or Thunderbolt or indirectly
through your network, and displays them in a list.
