To read wav file using c, you need to know the format in which the data is
stored in the wav file. I think this will help:

SOX is a free utility to convert audio files. Use that to convert the
WAV file to raw data.

Ya. SOund eXchange(SOX) would be helpful in this case, and we can do much
more with it. I have worked on it in Linux. But I don't know whether
"jadaayu" works in Windows or Linux. Is a WinNT binary available for SOX?

you'll have to worry about how to do DWT without any help from me, but
to read a wav file in C i think Erik, the MegaNerd, has free code for
you:
