-
- This is from "FAQ: Audio File Formats (version 2.5)" which was recently
- posted to alt.binaries.sounds.misc:
-
- ----------------------------- begin included text -----------------------------
- The most versatile tool for converting between various audio formats
- is SOX ("Sound Exchange"). It can read and write various types of
- audio files, and optionally applies some special effects (e.g. echo,
- channel averaging, or rate conversion).
-
- SOX recognizes all filename extensions listed above except ".snd",
- which would be ambiguous anyway, and ".wav" (but there's a patch, see
- below). Use type ".au" for NeXT ".snd" files. Mac and PC ".snd"
- files are completely described by these parameters:
-
- -t raw -b -u -r 11000
-
- (or -r 22000 or -r 7333 or -r 5500; 11000 seems to be the most common
- rate).
-
- The source for SOX, version 5, was posted to alt.sources, and should
- be widely archived. To save you the trouble of hunting it down, it
- can be gotten by anonymous ftp from wuarchive.wustl.edu, in the
- directory usenet/alt.sources/articles, files 5581.Z through 5585.Z.
- (These files are compressed news articles containing shar files, if
- you hadn't guessed.) I am sure many sites have similar archives, I'm
- just listing one that I know of and which carries a lot of this kind
- of stuff. (Also see the appendix if you don't have Internet access.)
-
- A compressed tar file containing the same version of SOX is available
- by anonymous ftp from ftp.cwi.nl [192.16.184.180], in /pub/sox*.tar.Z.
- You may be able to locate a nearer version using archie!
- ------------------------------ end included text ------------------------------
-
- I have found SOX to be easy to install and use.
