Great - if you want a 3D sound API for two speaker systems. Meanwhile, 4
and even 6 speakers are supported by several drivers now.

Cursory look eh? How's README for a start?:
OpenAL portable audio API.
See ./docs/index.html for more detailed information.
Okay, let's do that:
This document has been removed.
See <a href="http://www.openal.org/">www.openal.org</a>
The website (http://www.openal.org/info/) refers back to the CVS. There
are SGML docs, but these total a mere 7300 lines total for the entire
library, in pretty-printed SGML source code. How you document 15 megs of
source code completely or thoroughly in 7300 lines of mostly markup is
beyond me. I know enough to write a simple mixer able to handle 8 sounds
for two channels with independant volume and attenuation, but I can't
follow what is in the documentation directory.

Does the word "bloat" mean anything to you? It'd be one thing if we were
talking about hardware acceleration here, but we're talking about extra
dependencies on half a dozen libraries to add support for mp3 and vorbis
in software as part of the reference implementation. OpenGL is useful
because it is simple, well documented, and reasonably self-contained. So
far, OpenAL is none of these things! In fact, the package available for
my dist depends on libaudiofile, libesd, SDL, SMPEG, and libvorbis.
What, no libasound? hah. I know I saw code for that in CVS...
