Yes, this is essentially a one line program.  Here it is in C:

#include <stdio.h>
main()
{
  int c;

  while ((c = getchar()) != EOF)
    putchar(c - 128);
}

USAGE:  convert < sound.mac > sound.amiga
        convert < sound.amiga > sound.mac

Piece of cake!  Just remember, the header is destroyed in the conversion
process so you'll have to fix it up a bit.  For an Amiga, you can load the
file into a music program and save it as an IFF file (as the gentleman above 
suggested).  Or you can use a sound player program like "sound" that will
play any file and figure out the correct playback rate (a messy solution but
it works :-)
If you're converting from Amiga to Mac, you'll have to use a program 
(on a Mac) such as ResEdit or a DA such as DiskTop or DeskZap to 
change the file type to FSSD and the creator to FSSC so a Mac will recognize
the file as a sound file.
