There's four standard formats: AL_FORMAT_MONO8, AL_FORMAT_MONO16,
AL_FORMAT_STEREO8, and AL_FORMAT_STEREO16. 8-bit formats use unsigned samples,
and 16-bit formats use signed samples. Stereo formats are interleaved, so the
first sample is for the left speaker, the second is for the right, etc.
There's not much to ALC, except device initialization and queries, and audio
capture (which is detailed in the spec).
The AL extensions aren't too well documented, aside partly from EFX and X-RAM
which has documentation in the OpenAL SDK. For other extensions, there's some
info here:
