That the raw audio data on a cd is raw, and not a wav file... WAV files
have a bit of information that contains what the sampling rate is, the
channels and the bits per sample:
hydrogen,ttyp4,/home/johng,504$file /tmp/quarter.wav
/tmp/quarter.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 22254 Hz
so, if you want, you can use sox to convert the raw audio data into
wav:
sox -t cdr rawcddata.cdr somefile.wav
