similar to: codebook training

I'm trying to understand the residuevqtrain program, and I have some questions for Monty, Erik, or anyone that understands how it's supposed to work. I captured TRAIN_RES data from an encoding of a single track (about 4:43), producing two files, residue_0.vqd (3727 lines, = 3727 points?) and residue_1.vqd (huge). I then did a run with the parameters from the usage message

The VQ codebook generation utilities are more or less ready to go. Minor things are left to do, but those will have to be handled as I to them :-) The next thing to do is complete the interface to get compression modes and codebooks to the library for encoding (minor stuff), and then arrange how exactly the MDCT residue is filtered through the codebooks. VQ codebook util instructions:

Hi, I'm trying to build an lsp codebook to learn about the process, and I'm afraid that the vq hints http://www.xiph.org/archives/vorbis-dev/0000.html talk rather about residual training. So I can now produce .vqi files and add to them with lspvqtrain, but can anyone supply hints for the rest of the procedure? vqbuild will only produce a "cloud"-type quantlist, and sequencep

Hi all, <p>I have read the the source code about codebook generation, but there are some puzzles: Where can I get a latticebuild description file? How does one choose reasonable value0..value n on the second line of the latticebuild description file(.ql) to latticebuild? Does the output (xxx.vqi) of the resvqtrain have some relationships to the latticebuild description file ? Thank

Hi all, >From Monty's letter I know that ResVQTrain runs on vqd files that contain numbers separated by commas. I know that the .vqd files of this format generated by Vorbis compiled with RES_TRAIN contains partwords, i.e. codebook indeces assigned to partitions. I think that ResVQTrain should run on real data, not codebook indeces. Did I misunderstand something? Thanks Ervin

Is there any dump utility that exists for vorbis streams? What I am intersted in is something that will do a break down like: How many bits are used for encoding _each_ codebooks, how many bits are used for the residue, how much is used for the lpc coefficints. A selective dump of the codebooks themselves would be nice too of course. I'm wondering if anyone has such a little dump utility.

Hi, I am doing working on enabling Transcendent Memory(OLS '09) support on lguest. For the same, I need ballooning support for lguest. Is there an implmentation of Virtio Balloon driver, that I can use for my purpose? Could someone give me an insight, as to how to go about, for implementing this myself, incase I dont find this patch... Thankyou. -- Gaurav Kukreja +91 997 030 1257

WinRAR (ver 3.x) cannot create russian filenames on Samba shares - it got error: cannot create ????.rar Access is denied. But it can successfully create filename, contains only english characters. https://bugzilla.samba.org/show_bug.cgi?id=1407 Anybody has the same problem? Thanks a lot!

Hi, I've been using the Vorbis codec for a while and recently I got the source code and had a look at the spec (great job on the doc BTW). I don't have any former experience with audio compression, but I do know what a DCT does and I totally grok Huffman coding (so I guess I'm not that much of a newbie, am I?). Anyway I just had some questions about how VQ works on the encoding side.

Hello! First of all a question: When you make the encoder tables (ie: mode_e.h) do you use the mapping0_forward function? Because you made the encoder tables, and after this you did a minor correction in the final beta4 ... (this correction was: additional[0]=fabs(additional[0]*scale); in the mapping0_forward function) (I see this was a bug, and the modification was correct, but this correction

Hi, 1. "make install-strip" (in rsync-2.5.x) tries to strip the manpages and thus fails; attached is a patch fixing the Makefile logic (and also adding DESTDIR -- convenient for package-building or test-installing). 2. I just fetched rsync-2.5.2 but the build (on i686-linux) badly fails. The complete log from configure and make is attached. regards Peter Breitenlohner

ltconfig placeholder shoud be removed. Makefile.am : some stuff copied from branch_beta3 ogg lib must be added only where necesary. vq subdir Makefile.am'ized, (but installs nothing) made distclean target slightly more clean -- check it by hand first, please --- also you'll want to remove vq/Makefile if the ...am passes inspection ------------------------------------------------- diff

Hi, All. I am a new one to vorbis codec, I want to write a vorbis decoder, so I read the vorbis specification, but when I read the paragraph about codebook stream format. I am totally confused, can any one give me some detailed information about the codebook. Thanks in advance He Yang
