The original Microsoft specification listed the chunk size fields as unsigned 32 bit int, so what you are doing is correct. However, be aware that many programs (particularly on windows) using their own WAV file parsing code do not handle file bigger than 2Gig. > Is there a more general solution to 32-bit addressing limitation in > wave files? No. > Multiple chunks? No. Other file formats allow file sizes larger than 4Gig. I would suggest you have a look at AU and W64.
