  20. Here's a little hack I wrote to enable me to play NeXT sounds on my amiga.
  21.  
  22. #!/bin/sh
  23. # This is a shell archive.  Remove anything before this line, then unpack
  24. # it by saving it into a file and typing "sh file".  To overwrite existing
  25. # files, type "sh file -c".  You can also feed this as standard input via
  26. # unshar, or by typing "sh <file", e.g..  If this archive is complete, you
  27. # will see the following message at the end:
  28. #        "End of archive 1 (of 1)."
  29. # Contents:  Makefile README n2a.c n2a.uu
  30. # Wrapped by tadguy@xanth on Sat Mar  3 20:10:59 1990
  31. PATH=/bin:/usr/bin:/usr/ucb ; export PATH
  32. if test -f 'Makefile' -a "${1}" != "-c" ; then 
  33.   echo shar: Will not clobber existing file \"'Makefile'\"
  34. else
  35. echo shar: Extracting \"'Makefile'\" \(91 characters\)
  36. sed "s/^X//" >'Makefile' <<'END_OF_FILE'
  37. Xn2a: n2a.o
  38. X    blink FROM LIB:c.o n2a.o TO n2a NODEBUG LIB LIB:lc.lib
  39. X
  40. Xn2a.o: n2a.c
  41. X    lc n2a.c
  42. END_OF_FILE
  43. if test 91 -ne `wc -c <'Makefile'`; then
  44.     echo shar: \"'Makefile'\" unpacked with wrong size!
  45. fi
  46. # end of 'Makefile'
  47. fi
  48. if test -f 'README' -a "${1}" != "-c" ; then 
  49.   echo shar: Will not clobber existing file \"'README'\"

  52. sed "s/^X//" >'README' <<'END_OF_FILE'
  53. Xn2a converts NeXT sound files into 8SVX IFF  files.   NeXT  sound
  54. Xfiles  come  in  many  different  flavors;  n2a  groks  only  the
  55. XLINEAR_16 format, which is the one that most PD sound files  seem
  56. Xto be using.  NeXT recording applications use the MULAW_8 format.
  57. XYou can convert from this format to LINEAR_16 with the sndconvert
  58. Xapplication  on  the NeXT.  You can tell whether a sound file can
  59. Xbe processed by n2a using the command:
  60. X  od -b file | head -1
  61. XIf the last number is 003, then the file is in LINEAR_16 format.
  62. X
  63. XThe program compiles both on the NeXT and the Amiga.  I have pro-
  64. Xvided an Amiga executable, but I would recommend running the pro-
  65. Xgram on the NeXT, because the resulting 8SVX  file  is  half  the
  66. Xsize of the NeXT file.
  67. X
  68. XThis program is released to the public domain.
