'sox' works both on Linux and Windows and can accept data from stdin.

Under Windows sox' needs CYGWIN dll, but, I think, 'sox' is distributed in
binary for with the dll. I.e. in practical terms it behaves like regular
Windows console application - it doesn't need full fledged CYGWIN.

It might make sense to implement octave -> sox interface.
