I've been working on a library to encode/decode audio files (wave,

where I'm willing to share. It's available at
http://mml.music.utexas.edu/jwlato/HSoundFile/, lightly cabalized and
haddock-ified. The basic item is a Data.SoundFile datatype and a
SndFileCls class. Each file format (wave, etc.) has a datatype with
instances of SndFileCls and Data.Binary (thanks to Don S. for
suggesting Data.Binary). At least that's the idea, I've only
implemented the Wave format so far, but I wanted to make it easy to
add new formats.
sounds good!
I originally intended to use Erik de Castro Lopo's excellent
libsndfile (and there are some remnants of that in darcs), but after
realizing I wanted a more functional interface I decided to roll my
own. It's likely possible to wrap libsndfile in a functional
interface, but that is beyond my current abilities.
incidentally, i've been working on libsndfile bindings the last few
days; here's the darcs repository:
http://darcs.k-hornz.de/cgi-bin/darcsweb.cgi?r=hsndfile;a=summary
it's not quite finished yet, but if you're interested you could have
a look at the interface and make suggestions. maybe both projects
could benefit from each other? i personally don't see much advantages
in _not_ using libsndfile underneath ...
