Hi According to vorbis I spec, there are several configurations. There are 2 formats of floor, 3 formats of residue and 3 look up types of VQ codebook, etc. I think to get all kinds of vorbis file with these configurations but what I have got from network only support some of the formats (Ex. floor1, residue 1 & 2, VQ lookup type0 & 1). I downloaded several freeware vorbis encoder

Hi, all When I read the vorbis-I spec. In the section 1.1.6 Hardware profile, it mentioned that "embedded designs are allowed to deviate in limited ways from the 'full' decode specification yet still be certified compliant. These optional omissions are labelled in the spec. where relevant.". But I didn't read any relevant omissions in the whole spec and I have not seen

Hi, all I am studying the ogg-vorbis algorithm but I have less knowledge about the codebook structure of vorbis. After tracing the release source code, I found it doesn't use huffman tree to decode the huffman code instead of using a special mapping and pre-look. The memory requirement seems similar with huffman tree decoding. Could anyone tell me how the vorbis huffman decoding works
