Hello, I'm having problems to understand one thing in the floor1 encode and inverse functions in libvorbis 1.2.3 (I haven't had time to update myself to 1.3.1). There are some bitwise-and operations involving the floor posts, with 0x7fff and 0x8000, but I can't get to understand what's exactly their purpose... as far as I understand, that most significant bit is some kind of flag, but what exactly is it marking? I mean, what is the difference between a post with that bit set, and a post with the bit unset? Thank you. -------------- next part -------------- An HTML attachment was scrubbed...
