this is a semi-complete Real Audio file decoder for MSDOS.  It
will decode the original 14.4Khz files and the 28.8Khz files, but does
not know how to decode some of the other file formats that real audio
is capable of.  It also will not handle real media files at this time.

I have included an MSDOS play utility which will play the resulting
sample file if you have a sound blaster card.  If you do not have a sound
blaster, you will have to find a different play utility.  In the output
file from RAX, there are signed sixteen-bit samples at a rate of about
8Khz.

This stuff is PUBLIC DOMAIN, do what you want with it.  I didn't
write the decoders; just the shell for running them.  Note that
the 14.4Khz decoder does 32 bit math and will be slow for that reason;
the 28.8Khz decoder does floating point math and may be slow if you
do not have a coprocessor.

This stuff is built for real mode; I tried to get it to work on an 8086
but cannot guarantee it will since I don't have one to test it on.  It
should work at least as far back as a 286.
