Not necessarily. A format of 0xffff specifies the WAVE_FORMAT_EXTENSIBLE
file type. Assuming the file isn't malformed, any program whcih does
accept WAVE_FORMAT_EXTENSIBLE files is broken.

May I suggest you look at libsndfile:

    http://www.mega-nerd.com/libsndfile/

which includes two programs:

    sndfile-info    - Prints out information about files.

    sndfile-convert - Converts between file formats including Ogg
                      and WAV.


If you use sndfile-info on the file produced by off123 then it
will tell you if the file is malformed or now.

sndfile-convert will convert to a standard old format WAV file.
