- NeXT sound files come in two flavors, linear-16 and u-law (that's
- Greek "mu"-law). There are a number of utilities to convert the
- files, depending on which sort of file you have. If it's linear-16,
- you should use either SOX or a program called n2a, which I could mail
- to you if you can't find it anywhere. If it's u-law, use either
- ulawto8svx, SoundZAP, or SOX. You might have to strip off the first
- four bytes of a u-law file to get one of these programs to convert it.
- Do this with a text editor that reads and writes 8-bit characters,
- such as CED or GNU Emacs, or with a stream processor such as
- Unix-style "tail". If you don't have a true Unix-style tail (i.e.,
- implementing head-relative and tail-relative tailing of lines, blocks,
- or characters) I can send you one.
-
- SoundZAP and SOX are available at finer Amiga FTP sites everywhere.
- Check wuarchive or any of amiga.physik.unizh.ch's cohorts. At
- wuarchive, the path used to be /systems/amiga/incoming/audio/* (where
- * is some suspicious-looking filename), but it might have since moved
- to /systems/amiga/audio/utils or some such spot.
-
- If you use SOX on a linear-16 file, you'll have to strip off the
- first 24 bytes of the sound file and convert it as raw 16-bit signed
- data. (SOX doesn't know this format yet on its own.) You'd then have
- to load it into a sample editor and adjust the playback rate to
- whatever it should have been.
