So will Timidity.  mpg3 I don't think does that.

Thanks.  I downloaded the Feb 11, 2007 Sox 13.00 (about 700K source code) 
and it compiled in BL2 with no tweaking!  It needs libst.so.0 (which got 
compiled at the same time), libm, libc, ld-linux.

play and rec are now symlinked to sox in /usr/local/bin, rather than play 
being a separate script.  The man pages are also linked.

The old sox from 1999 is 120K and the new one 100 unstripped or 30K 
stripped.  But it requires a large new library (809K libst.so.0).

'make install' did not install libst.so.0.0 so I copied it manually 
(with symlinks to so.0 thence to so) to /usr/local/lib, where it was not 
found, then to /usr/lib, where it was found.

It also did not delete /usr/bin/sox and /usr/bin/play when it installed 
the new files to /usr/local/bin, so I renamed them myself and will delete 
them.  Ditto for the old sox and play man pages.

The new 'play' plays a wav file and lists sample size, unsigned, 1 
channel, 11025, and time elapsed.

I manually copied files from /usr/local/bin /usr/local/man 
/usr/local/include and /usr/lib to a separate directory.  I cd'ed to the 
root of it.

I ran makepkg, which made install/doinst.sh, then I edited doinst.sh made 
by makepkg (which removes old versions of things in /usr/local and makes 
symlinks to sox from play and rec) to also remove the 1999 SW7.1 version 
before installing the new version by adding at the top of it:

(cd /usr/bin ; rm -rf sox )
(cd /usr/bin ; rm -rf play )
(cd /usr/man/man1 ; rm -rf sox.1.* )    will remove gz version too
(cd /usr/man/man1 ; rm -rf play.1.* )   will remove gz version too

I deleted the original .tgz file and made a new one, which incorporated 
the new doinst.sh.

Someone please test it to make sure things get deleted and symlinked as 
they should.

Is there an easier way to do all this?

I tested play but not rec.  Needs the SW8.1 glib (libc, libm, ld-linux) 
which you can add to BL3.

Thanks, David
