Have a look at the zita-alsa-pcmi library. It probably does all
you need - it takes care of the zillions of calls necessary to
initialise mmap access, and provides/accepts floating point audio
samples regardless of the soundcard's format. No documentation ATM
but the examples should get you going. It's C++, but using on the
class mechanism, no templates, dependency on C++ libriries etc.


Vor uns liegt ein weites Tal, die Sonne scheint - ein Glitzerstrahl.
