For a different take, consider audio APIs. I've yet to find a man page that tells me how to use ALSA. There's a clutterfuck of doxygen docs if you want to get lost.. https://www.alsa-project.org/alsa-doc/alsa-lib/

Or you can buy a nice little library from OpenBSD where the PCM part is sufficiently described in one short man page: http://man.openbsd.org/sio_open.3

(With enough detail so that you can use it to write e.g. a latency-aware rhythm game that manages to keep audio and video in sync...)
