Certainly; file conversion is one of the basic purposes of sox. Something
like:
sox myfile.wav -b 16 -e signed -r 22050 -c 2 myfile.raw
will convert the wav file (whatever its format is) to a signed 16-bit stereo
raw file. For raw files, you can also use special file extensions that
specify the encoding ("myfile.s16" for example, for a signed 16-bit file).
Adding "-V3" to the beginning of the command will print the full input and
output specs, plus the filter chain required to do the conversion (if any).
The sox and soxformat manpages are pretty comprehensive.
