Hi folks, some notes about goings on. After opportunity to think aloud, I have the pieces of the VQ system more or less in place. I need to finish the codebook generation core (this is not libvorbis code, but an external utility). I then need to write the encode/ decode/packing code that makes use of the codebook. This future code is already specced. Tony: I haven't worked on the xmms

The changes to vorbisfile that I suggested earlier have now been committed - this is mostly a merge of my code with a similar patch from Martin Vogt (thanks Martin). The old ov_open() interface remains untouched - and for many people, this is all you'll need to use, ever. It now calls the new interface with appropriate arguments. The new ov_open_callbacks() function adds an extra argument to

Hi folks, I've been dickering around again, wasting the time away.... and today Brian Zisk (chief Vorbis Evangelist among other things) said, "Hey! We need to demo to the world on the 4th of April!" Hooo boy. Time to suck it up and bang it out. The Vorbis libs are not a problem. I'm in process of checking in my new psychoacoustics (they're real pretty!) based on

Hi, I need a psychoacoustics model for some experiments and would like to use the one included in vorbis. Is there any documentation about how to use it? Looks like the relevent code is in psy.c, but I can't go further. Also I would like to know whether I can be of any help in vorbis. I have some knowledge in speech coding (I doing my master at the University of Sherbrooke's speech

Ok I just finished writing a Vorbis encoder/decoder, and here are some of my comments (I'm sure some of these are well known, but here they are anyway - sorry this is long): 1. vorbis_info: a. Accessing the pre-computed info structs through pointers to static data is messy IMO. I should be able to vorbis_info_init (or similar) an info struct to be exactly the same as info_A, for

[ I'm not in the list because I didn't find a digested version; please move the lists to sourceforge.net, and we would have the digested version. I read the replies from the archive. ] Hello. Would it be possible to allow Vorbis use the same codebook for multiple files? I could keep a 650 MB codebook on CD-R and use that for all my audiofiles. If that is possible, how much the

OK, into the nitty-gritty, albeit a high-level version. If it sounds like I'm glossing important details, you're right. This discusses only the basic DSP; precise coding, framing, sync, etc, will be in another mail. Vorbis is a hybrid transform domain general purpose audio encoder, like MPEG in some respects (it is rooted in much of the same basic theory). For the most part, the

Hello folks, This is a ping to see what folks are up to and planning to work on in the near future. I'm mostly just curious.... Personal goals in the next week: Handle any incoming bugs on the vorbisfile API/library Hone the LPC approximation routines a bit more. Get the command line player functional (Mike Whitson is also planning to put some time in here). Verify that I understand the

Nothing on a branch yet; I'll be building a temp branch for my changes soon. First, I'm eliminating ordering dependancies in vorbis_block structures. They'll be totally sepreate and vorbis_analysis won't have a global state in vorbis_dsp_state that requires them being done in order. That way, a parallel-threaded encoder can run multiple vorbis_blocks through multiple

The following has been committed to the Vorbis I spec as of r19445: Errata 20150226: Single entry codebooks A ?single-entry codebook? is a codebook with one active codeword entry. A single-entry codebook may be either a fully populated codebook with only one declared entry, or a sparse codebook with only one entry marked used. The Vorbis I spec provides no means to specify a codeword length of

I'm updating my vorbis rpm spec file, and when I try to do "make -C vorbis-tools ogg123", due to rpm's build environment, I get lots of: gcc ogg123.o -o ogg123 -lm ../lib/libvorbis.a ../lib/vorbisfile.a ../lib/vorbisfile.a(vorbisfile.o): In function `_get_prev_page': vorbisfile.o(.text+0x54): undefined reference to `ogg_sync_reset' vorbisfile.o(.text+0xa9): undefined

Hi there, after browsing the mailing list archives for several hour I still couldn't find an answer to my problem, although it for sure sounds as if many people posted the same problem. Yet, none of the threads dealing with problems like these matched my problem, so I have to start a new thread on my own. This is my system environment: Linux machine: - Mandrake Linux 8.1 - samba-2.2.1a

Hi, From the vorbis decoder specification, it is clear that the decoder needs to have all the codebooks before decoding can actually begin. I will appreciate if someone can clear the following questions: 1. I guess the codebooks are derived from the actual input data. Probably the encoder may be making two passes through the input. The first pass finds out the frequency of different symbols

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 ?
