I really recommend time critical priority for audio threads --
that's what that priority is for! If you get a permission error,
then fall back to HIGHEST.

SetPriorityClass() is what bumps up the priority for your
process in general. I wouldn't set the process class to
real time priority, though, that might have bad effects on
the rest of the system :-) HIGH or ABOVE_NORMAL are the values
you can play with here. ABOVE_NORMAL doesn't exist on DOS
based Windows.

The full table of class + priority mapping to actual thread
priorities as used by the scheduler is found here:

e/scheduling_priorities.asp

It's too bad that you can't make a single thread real time
without making the entire process real time, so TIME_CRITICAL
is as good as it gets.

Cheers,
