It was actually a surprise to see there is no strsep(3) in mingw, so I

Ok. I moved the help to a DOCS/tech document; such a document is
necessary anyway so
it is a good starting point.

They are wav files; MPlayer tries to parse some of them as mpeg.

Mingw refuses to link this function. Cygwin instead, has a strsep()
that works the
same way as mine. I used Macintosh documentation ("man strsep" in
firefox results in
hmug.org) to write it. Strsep is simpler and thus safer than other
such functions; the
question is not whether to use it, but rather how to maintain
portability with it. I
removed the ifdef and renamed the function to str_sep().

Ambisonics derives from math, it hasn't any de jure standard except
(there were some patents but they expired many years ago). There is plenty of
documentation in internet, and its community consists of people having
points of view (for example: scientists vs. content creators). Try to
'ambisonic'. You may be disappointed by the amount of existing
software--my filter is
one of the first freely available decoders.
An updated patch is in attachment.
