If you need to read WAV files, why not just use libsndfile: http://www.mega-nerd.com/libsndfile/ and the libsndfile Ocaml wrapper: http://www.mega-nerd.com/tmp/libsndfile-ocaml-20071120-0622.tgz It's basically working, but there might still be some slight API changes. The reason I suggest this is that WAV file parsing is probably much, much harder than you immagine. Here's why: - WAV files allow the audio data to be encoded in dozens of different formants. Supporting even a small subset of them is a PITA. - There are numerous programs that create malformed files. Adding workarounds to these is a lot of work. - libsndfile already supports a whole bunch of other file formats.
