I still would like to suggest to make clear difference between
the actual code and the plug-in wrapping. It would be quite simple
to have compressor/limiter functions which are then used in various
plug-in wrappings.
I don't know what constitutes as "low-level" but I'm writing things
like filter design utilities to my code libarary. Think about Matlab
as C library with a toolbox for low-latency audio. Matlab, Octave,
Gnuplot etc. are good as a standalone but in practise I have had
a need for flexibility of C -- well, at least I were able to do special
stuff in C but not in Gnuplot. Benno's latency test is exactly of such
a type of code which gets me smile: it performs the test, collects the
data, and does plotting in the same code -- it could be turned to
interactive program or to do something special (stress the disk more)
with simple modifications. Though, not everything needs to be done
in C.
