+ .Nm
+ can be used in server mode
+ .Pq Fl l
+ to overcome hardware limitations and allow applications
+ to run on fixed sample rate devices or on devices
+ supporting only unusual encodings.
+ It is generally not desirable to have multiple
+ instances of
+ .Nm
+ running in server mode,
+ so it is good practice to start it thus:
+ .Bd -literal -offset indent
+ $ pgrep -x aucat || aucat -l
+ .Ed
+ .Pp
+ This also ensures privacy by preventing
+ other users from accessing the audio system.
+ On multi-user machines
+ .Nm
+ should be killed when no longer in use to make audio resources
+ available again to others:
+ .Bd -literal -offset indent
+ $ pkill -x aucat
+ .Ed
+ .Pp
+ Certain applications, such as synthesis software,
+ require a low latency audio setup.
+ To reduce the probability of buffer underruns or overruns,
+ the
+ .Xr renice 8
+ command can be used to give higher priority to
+ .Nm
+ process to.
+ Superuser privileges are required.
+ For example:
+ .Bd -literal -offset indent
+ $ aucat -b 3500 -l
+ $ sudo renice -n -20 -p `pgrep -x aucat`
