Hi all,
I want to extract Raw PCM data from .wav file, I have gone through
RIFF format for .wave files

RIFF( 'WAVE'
<fmt-ck> // Format
[<fact-ck>] // Fact chunk
[<cue-ck>] // Cue points
[<playlist-ck>] // Playlist
[<assoc-data-list>] //Associated data list
<wave-data> ) // Wave data

i am not getting information about how to decide whether optional field
(in [ ] ) are being used or not? or they are not for .wave ?
also can any one have link/code for extracting Raw PCM from .WAVE format?

Thanks in Advance,
Rahul.

These days, one must ~expect~ other chunks to appear between <fmt > and <data> - including all or any of the above. You can even legally have chunks between the opening RIFF<WAVE> and <fmt >, though I can't remember the last time I found that in a file. So that site (like so many, sadly) is giving a wrong idea of how the format works. The solution however, is easy - just ignore (skip over) any chunks you don't know about or don't need.

Or, even more simply - use libsndfile!
