I had developed a WAV header reader that should work with almost any WAV
file the problem could come from very damaged WAV headers, but the code
have a switch to block this very large headers. It is attached to this
message and should be easy to join in vorbize or any other ogg project. It
uses the RIFF struct used in the vorbis-tools code.
This is the comment in the code:
// This file is intented to parse WAV headers from a file and report
// information to a main code portion without loosing any data if the
// file is not a valid WAV file, or the WAV file is damaged.
// stdin should work ok, but probably this code need a little tweak in
// the chunks parser to avoid memory problems in large padded WAV files
// to remove silences because the RollBackBuffer could grow to a undesirable
// This piece of code should be easy to port from Win platforms to any other
// and should be endian free, but I can not test this point.
// The "int main()" function is included as an example on how use it.
Try to mix it in you code or simply drop it to your waste basket :-)
