similar to: Vorbis encoder?

I've made block diagram of the encoder because I tried to find out, how it works http://stoffke.freeshell.65535.net/ogg/block.html Although there are specifiation docs, that give very detailed information about single aspects of the encoding (or decoding) , I'm missing documenations that give a more general overview, about how the encoder works. (Vorbis Illuminated seems a bit outdated,

Hello, Vorbis uses codebooks, for example to do vectorquantization and huffman-encoding. My question is - are all these codebook dynamicly generated ("trained") or are there also static codebooks used ? If yes, what specific tasks are these 2 types used for, during encoding ?

Hello, I would like to "piggy-back" other data in an Ogg/Vorbis I physical stream (i.e. file) in a manner that does not conflict with specifications and existing decoders/players/editors etc. As far as I can see, I have some possible choices: 1 - Chaining a logical bistream at the end. If this is the way to go, two questions arise to begin with: q1a - How to identify this stream in a

Hi there In the past, i have used lame to encode high quality mp3-files (vbr 1, bitrate ~ 192kbit). I tend to switch to ogg with Quality 4 or 5, but i noticed, that many ogg-files tend to produce too much high frequencies response. In many cases, this is very noticeable. For my opinion, i cannot accept this worse frequence reponse. I have used latest version of ogg (OggEnc v1.0, precompiled

This is the first draft of the audio/vorbis media registration form to be handled to the IANA. PLEASE comment extensively, even minor spelling mistakes etc are to be stamped out of this I hope. A media type for application/ogg (or should it be application/oggsquish?) will be created separately. I would be very happy if someone could supply the 4-letter filetype code used by MacIntosh .ogg files.

Hi, it seems to me as if all vorbis-files only contain floors of type 1 and residues of type 2. Is it possible to "force" the encoder to somehow create a vorbis-file with the other floor and residue types?

I have been using libvorbis for the past few weeks and have been asked to summarise what I have discovered about the codec. There is an early draft of the document at http://www.geocities.com/gatewaystation/vorbis/vorbis.htm - Please forgive the dodgy formatting (it was formerly a MS word document that got converted with their 'save as html' feature). I still have some additions to

I have developed a flexible arithmetic coder implementation and I am now looking to incorporate it into a compression system for some proper testing. It is my intention to incorporate the coder into the Vorbis codec to attempt to improve on the current Huffman tree system. It would be useful if someone could point me at the main c and h files that deal with the entropy coding as I am currently

Hello, I wanted to find out more about square polar mapping, cause that whole stuff is a bit tricky - to me - and not so easy to understand. Searching the web did't get me any results, so I wonder what the background of square polar mapping is. Is it derived from some mathematical publications or just the result of a brilliant intuition of a Vorbis programmer ? ;) Thanks. Stoffke

Hello, I have a few questions about the block size in ogg vorbis 1. The allowed blocksizes are powers of two between 64 and 8192 Samples. As I understood , there are fixed sizes for long and short blocks . The encoder can pick any allowed value for long blocks and onother value, that must be smaller or equal to the first one, for short blocks. On which base does the encoder choose the size for

Hi, I've found some more errors in the file format specification (or at least points, where the specification and actual libvorbis implementation mismatch): - Floor 1 / curve computation / step 1: amplitude value synthesis 21) vector [floor1_final_Y] element [i] = [predicted] - (([val] - 1) divided by 2 using integer division) hould be: 21) vector [floor1_final_Y] element [i] =

Hi, I am trying to implement a Vorbis decoder in Java, and I have some problems understanding the file-format specification included with libvorbis. In the header description, there are a few obvious mistakes, which I believe to have solved, but when I try to decode the audio packets, the decoded floor and residue data doesn't seem to make sense at all, and after a few packets, my decoder
