.vqd example?
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

cvs trunk vorbis/ compile patches
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

codebook training
Hi, I try to build codebooks for Vorbis at sampling frequencies other than 32/44/48 KHz. As the first step, I started with residual codebooks. I generated training data on a one minute long 44 KHz audio, using Vorbis compiled with the TRAIN_RES define. I think it worked fine, it generated .vqd files for me. Then I compiled ResVQTrain, which complied OK. Then I run it on the previously

questions re residuevqtrain
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

newbie questions about VQ
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.

Minor fixes for libvorbis-1.0beta3/anoncvs 2000-11-08
Hi there, I just built libvorbis from anoncvs and found that a) some files are missing from lib/books when making dist and b) the GNU GPL instead of the LGPL is included in the package (contrary to what the README says). If you reply, please includ me in the Cc: because I'm not on the list. The missing files are: res0_160_1024_1.vqh res0_160_1024_2.vqh res0_160_1024_3.vqh

encoder observation
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

vqd file format
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

Query Regarding Vorbis Audio codec
Hi, I have a Win32 folder in libvorbis folder in which i have dsw executable file, I have Visual studio 2008 so I ported that into VS2008, then I downloaded ogg lib and included that also. After that _V_SELFTEST has been defined, then its asking the definition of these two header files #include "vorbis/book/lsp20_0.vqh" #include "vorbis/book/res0a_13.vqh" I commented this and

Modification requests / question
Hello! 1. You should modify the 'vorbis_ftoi(f)' for the undefinied OS/compiler in the 'os.h' on this way: old: static int vorbis_ftoi(double f){ return (int)(f+.5); } new: #define vorbis_ftoi(f) ((int)(f+.5f)) Because in some cases we don't use this function, and the compiler writes many error messages. 2. Could you write a frequency and bitrate independent

vq diffs
please add the following diffs to the vorbis/vq dir. - include files changed so things actually compile in new scheme - _ogg_...alloc cleanups caught a half-dozen typos or so - minor Makefile touchup. (stuff is still not tested, but this will compile at least) Would someone with cvs write access commit them for me please? Erik diffs: ------------------------ diff -bBu2r vorbis/vq/Makefile

Hi all, 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 you!

Sorry, I pasted the wrong file in earlier... this is the correct one: pValCalculator(b, n=20, m=20) { ind <- 1:min(c(n,m)) prob <- (1-pnorm(b,sd=std*sqrt(ind))) prob1 <- sum((n-ind+1)*(m-ind+1)*prob) prob1 } inputData <- scan("/users/lvssso/projects/LAMA/output/pValLamaScore.tmp", list(block1 = "",block2 = "",width1 = 0,width2 = 0,alignment = 0,score
