I provide a 32 and 64 bit windows setup.exe style installers. Those
installers provide libsndfile-1.dll, the required header files and
documentation and a couple of exampe Visual Studio projects.

libsndfile is releases under the LGPL license so one executable is
not possible unless you release your source code.

But what does that data represent? Shuffling pcm audio data around as
BYTE arrays is a brain damaged practive encouraged by Microsofts APIs.

That completely depends on what that data represents. The libsndfile
source code tree contains numerous example and demo projects. YOu 
should look at those to begin with in conjunction with reading the
documentation.

In that code, data was a pointer to short. See:

and frames is the number if frames of shorts. See:
