FWIW, CsoundAV can actually do real time audio output and write to file
concurrently, without the fout.

As described in the AV manual, it's possible to do both from the command
line (using MME or DirectSound), but unfortunately, the file written is raw
(headerless) and cannot be played by media players I'm acquainted with.

The method described under "GUI" (section 2.2 of the AV manual) details
another method which purportedly also creates a raw .wav file. However, it
creates a file with *normal header*, or at least one playable by a usual
media player (such as Windows Media Player).

I note this as it seems the only current way in Windows to render live and
to file simultaneously, without modifying a live performance .csd. As I'd
like to "record my performances" and post some MP3's of my pieces to the
web, this capability of CsoundAV will be quite handy.

(One of the reasons why I'm doing this is because now I have a "real"
website, http://www.arthunkins.com, which allows music files (.mp3) to be
posted - thanks to a Christmas present from a family member.) Goodby
freebie.

With fout, are floating point files always written without a header? If 
a header is possible, how?
Would it be possible to add an option for headers for 32bit files in the 
future? It'd make importing into other software much easier.
