Why not use a proven library for doing this? Personaly, I recommend
libsndfile :

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

which will allow you to save the file as AIFF, WAV or any of about 10
other formats. It allows you to handle your data as floats, and specify
that the output file should be 24 bit PCM (or any of a number of other
subformats) and the library automatically does the conversion on the
fly.

libsndfile is release under the GNU LGPL which means that you can use it
with Free Software, Open Source, proprietary, shareware or other closed 
source applications as long as libsndfile is used as a dynamically loaded 
library. With applications released under the GNU GPL you can also use 
libsndfile statically linked to your application. 

Erik (who has spent too much time working on that thing to want to see
      other wasing their time writing AIFF or WAV handling code).
