Let me explain respectively.
OSS - libsndfile has not much to do with OSS. It mainly focused on
processing data from one format to others. It does not like to deal much
with hardware or operating systems. The only exception may be
sndfile-play. Sndfile-play is one of three tiny utilities it provides,
which only writes audio data directly to /dev/audio (on Solaris), which
is standard audio device on Solaris. On SunRay sndfile-play wont work
properly because SunRay client uses another audio device specified by
$AUDIODEV. However, it is not a main purpose of libsndfile.
Overlaps -
SoX is an all-in-one, command line based, audio converting tool.
It does not provide APIs to other program.
Libaudiofile is fairly out of date. The last update is released in
2004. Libsndfile is more active.
Audioplay/record/convert are legacy tools. Libsndfile could covert
most of their functions except recording, however, I would like to use
another new case to EOL these legacy tools, considering there may be
dependencies on those legacy tools. That needs more effort to
investigate other than this case.
On more reason that I wanted to integrate libsndfile is that the library
is widely used by many opensource softwares. With this library, we can
expect more audio processing tools in Solaris.
Thanks,
- Chris
