Still curious about RAUL. As i have no immediate plans beyond learning how
to write proper audio app, even if license restrictions prevent from using
RAUL in a hypothetical commercial product years down the road, it may well
be worth me using for my own personal needs in the meantime.
Would love to hear feedback on technical merits of RAUL, minus license
conversations which now have my other thread. ;-)
heck I'd like to hear about any other libraries worth looking into too. I'm
trending at the moment to STK, embedded csound, Jack, and QT for gui. The
part I need library help with is likely synchronization and
interprocess/interthread communication. ( ie do I use the jack ringbuffer?
Do I look at boost queue implementations? does RAUL have a higher level
convenience ring buffer?
thanks!

my boost.lockfree library has been accepted and will be shipped with future
boost releases. it contains an mpmc-stack, an mpmc-queue and a wait-free spsc
ringbuffer (same algorithm as the jack/kernel/supercollider ringbuffer).
git repo: http://tim.klingt.org/git?p=boost_lockfree.git;a=summary
(note that the addressing_reviews branch will be the one that will go into
boost)

Thanks Tim, I'll def check it out. What's the difference to a newbie like
myself between yours and the one in Jack?
Congrats btw, that's awesome that your work will be in boost!

the main difference is prbly that the jack ringbuffer is plain c and prbly
needs libjack, while boost.lockfree is a c++ library and header-only.

Great, I'll likely be a user then! Was planning on using boost whenever
possible anyway.

Actually, this one is a bit better (less barrier overhead), but I will
update the Raul one to be identical (but for C+eyness) soon.
Zix is basically a minimal data structures library where I made the
things necessary to drop the glib dependency from my LV2 stack. It is
newer than Raul which has been around for some time.
Random aside for the data structure inclined: I attempted to replace the
hash in sord with a patricia tree (since I hate clunky
rebuild-the-world-occasionally data structures like hash tables) but I
was unable to compete with the hash for small key sizes which is the 99%
case for LV2. However, if you need a dictionary keyed by *long*
strings, ZixPatree completely destroys ZixHash and GHash according to my
benchmarks, particularly if you have SSE4.2.
I would still very much like to have a realtime safe and thread safe
string dictionary for interning. This would be very useful for LV2. I
am not sure if it is feasibly possible, though.
