libsndfile (http://www.zip.com.au/~erikd/libsndfile/) provides an
excellent simple API for addressing data, and read/write in
short/int/float/double (virtualised, ie. independant of what's on-disk).
Although it doesn't give explicit support for file properties it would
probably be trivial to add (via the existing sf_command() interface; Erik?)
You would probably save yourself the most time by contributing your
file readers to that (and then other applications built on libsndfile will
benefit from your work also :))
Next, you would write abrowse to use libsndfile, which is easier than
falling off a teflon log after drinking a bottle of vodka:
http://www.zip.com.au/~erikd/libsndfile/api.html
and you would instantly be able to export to not just WAV but also
AIFF, AU, and a bunch of others, even in floating point where possible.
Also, if you wrote file writers for each sample patch format, you could
just as easily convert between formats, even changing bit width on the
fly ...
Conrad.
