About
SoX, the Sound eXchange program, is a general command line utility for processing, playing, and recording audio.
For single input files, it can:
- perform basic editing
- apply effects
- return information (via SoXI)
For multiple input files, it can be used to:
- mix them together
- concatenate them serially
- use one to effect another

Notes
The documentation for bitrate and channels seems to be slightly wrong. If you use the -c or -r options before the first filename, that's treated as an expectation of the input file's format. If you want the output file to use a different number of channels or bitrate than the input file does, you need to use the channels or rate options after the output file.
Example:
sox <input filespec> <output filespec> rate 44100 channels 2
(Actually, I'm not sure whether it's using the fully-spelled version or the placement that makes the difference; experimentation needed.)
