M Series Core Audio driver for macOS
On macOS, to enable your M Series interface in
your Core Audio-compatible host software, go to

software where you choose the audio device (Core
Audio driver) you wish to use, and then select the
M2 or M4 by name.

Sample Rate (Hz)
Choose the desired sample rate (Figure 2-3) for
operation with your host software. Make sure your
host software matches the sample rate you choose
here.
Buffer Size
The Buffer Size setting (Figure 2-1 and Figure 2-3)
determines the amount of latency (delay) you may
hear when live audio is patched through your host
audio software. Smaller buffer sizes produce lower
latency, with sizes of 256 samples or less producing
virtually imperceptible delay. Many host
applications report audio hardware I/O latency, so
you can see what happens to the reported latency
when making adjustments to this setting.
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.
