You can't simply join the two files with something like the AmigaDOS "Join"
command.  You could write (or buy) a program to read in two IFF 8SVX
(eight-bit sampled sound) files, combine them and write out one file.
Combining one IFF and one "raw" file wouldn't work.  There is a limit
to the size, but it is pretty large: the largest number representable by
32 bits!

It can and it has.  I used PerfectSound to digitize over three and a half
minutes of music at something like a 16 KHz sampling rate.  Dan Baker
of CATS had written a program that would spool the file off of disk and
play it in real time.  Great fun, but (as you say) not practical unless
one has disk space to burn!
