I saw many answers to your question but no specific command line to
execute, here is what I would do to convert your RAW file to WAV:
sox -t raw -r 44100 -s -w -c 2 file.raw -t wav file.wav
CD audio is:
-r 44100 : 44100 hz sampling rate (number of times the level of the
audio signal is "sampled" per second)
-s : signed data format (2's compliment signed binary data)
-w : words (16 bit, i.e. 2 byte samples)
-c 2 : stereo (2 channels)
If you haven't already checked it out "man sox" will give you some good
information.
