I would suggest reviewing the code for systems that do the same.
see also the 'sound(4)' page for relavent refs.
CSound / snd and other 'synthesis toolkit' kinds of
things might be a good candidate.

With judicious use of cpp macros. :D
Serously though, alsa for linux has an oss api emulation,
and theoretically a userland library for non-alsa (read non-linux)
platforms exists / works, though I haven't had luck with it
Alternately you can write for a platform-independant library/API
such as jack / esd / nas / SDL, portAudio etc.
I would probably suggest this to start with since dealing
with low-level audio is pretty tricky and unrewarding -
lots of things about buffers and latency and various stuff,
unless you want to learn these things directly. This also
to some extent isolates your code from underlying system
the linux audio pages http://linux-sound.org/ are a really
good mostly-linux centric reference, but various references
there will be generally applicable to general audio under
unix-like systems and some will be highly cross platform, etc.
I would suggest spending a good deal of time reviewing the
packages in pkgsrc/audio and figuring out which might fit your
needs or serve as a good example and build from there.
Note: not everything builds / runs 100% with all features
on DragonFly there, so keep this in mind & expect to
