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 lowering the safety offset, or raising it signif-
icantly, as this parameter can have a major 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 indirectly through your
network, and displays them in a list. Choose an
interface to access its settings through the web app
(“MOTU Pro Audio Control Web App” on
page 11).
MOTU PRO AUDIO WEBUI SETUP FOR
WINDOWS
On Windows, the installer provides a MOTU Pro
Audio WebUI Setup shortcut found on the
Windows desktop or in Start menu> All Programs>
MOTU. Use this shortcut to access the MOTU Pro
Audio Control web app directly in your favorite
web browser.
MOTU AUDIO TOOLS
The installer places the MOTU Audio Tools app in
the Applications folder (Mac) and Programs
(x86)>MOTU (Windows). MOTU Audio Tools
provides advanced audio analysis tools, including a
full-screen real-time FFT display, spectrogram
“waterfall” display, full-featured oscilloscope, X-Y
plot and phase analyzer. See chapter 9, “MOTU
Audio Tools” (page 71).
AUDIODESK WORKSTATION SOFTWARE
AudioDesk is an advanced workstation software
package for Mac and Windows that lets you record,
edit, mix, process, bounce and master multi-track
digital audio recording projects. Advanced features
include real-time effects processing, recording,
and much more.
See the AudioDesk User Guide, available on your
computer hard drive as a PDF document.

WORKING WITH HOST AUDIO SOFTWARE
For further information about using the LP32 with
host audio software, see “Working with Host Audio
Software” on page 55.
