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

Dump utility?
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.

Bug-fix release?
Hi, I'm not a developer, just a keen observer and hopefully user in the near future. I'm very excited about CELT's potential for broadcasting. Don't mind me sitting in the corner. I was just looking over recent posts and read this one: http://lists.xiph.org/pipermail/celt-dev/2008-October/000003.html Are there any plans for a bug-fix release, or is a 0.6 expected soon?

lattice codebook
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

help - about the vorbis codebook
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

New package: codebook
Dear R users, codebook (v. 0.5.8) was just released on CRAN. https://CRAN.R-project.org/package=codebook It uses the metadata/attributes that some other packages add (item labels, value labels, labelled missings) to automatically generate a codebook that is both human- and machine-readable. It combines metadata about the variables with data summaries. Many people will import this kind of

Speex Command line, Changing the LPC order and modifying the codebook
Hi, can someone help me understand and experiment with Speex in a better way than my knowledge. I want to change the LPC filter order of the Speex algorithm. I think I need to change the LPC order( or lpcSize) in modes.c file. but to make it work I need to modify the codebook also, can someone tell me how to go about changing the codebook entries to support the changed order of prediction.

Distances in codebook search
Bj?rn, I would be very interested in looking at your data and the R file. Actually, I think a lot of people would. You might want to post it on a website...

Query in codebook decoding
Hello Monty, Sorry for the wrong subject title last time. A little more clarification needed. When reading bit-by-bit, there is no MSb/LSb, just 'first bit' and 'last bit'. The Huffman tree is traversed from 'first bit' to last bit'. This is a conceptual layer above the bitpacker; all you need to know is what order the bits come out, which happens to be LSb-first.

Do codebooks always start at byte boundaries, or can they start at arbitrary bit positions after the first codebook?

Codebook verification
Is there a utility available that will dump the codebook information for a given Vorbis file. This would be useful to compare my own implementation against as a benchmark. Actually, a utility that would dump all of the Vorbis metadata would be quite useful as a development tool.

Creating a text codebook
Is there a currently existing method in an R package for creating a codebook from a dataframe? Preferably, I would like to be able to export to a text file all relevant information. Thanks, Harold [[alternative HTML version deleted]]

huffman codebook
Hello, I was wondering if it is possible to change the huffman stuff? A different mapping maybe, or maybe it is not too late to change? Decoding is much more efficient if: -- the huffman tree is left-aligned (i.e., longer codes more to the left) -- and we get the bits msb, not lsb Oh, and I need some clarification about the lsp: the purpose of the lsp is to find a low-bitcount approximation of
