I found all I needed to know about the header(s) of *.wav files and what they mean from this web page:
http://www.topherlee.com/software/pcm-tut-wavformat.html
It says there:
“The header of a WAV (RIFF) file is 44 bytes long and has the following format:” .
In the case of the *.wav file I had, the header was actually 46 bytes long, but very very close
to what they say at:
