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 is pretty much ignored. But if you use it anyway, you can go by hand through the xxx.vqh file and guesstimate enough to make a bogus .vql file. Then I ran latti...

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.

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

...P coefficient sets are like this 2) data sets where the values are not monotonically increasing; essentially 'everything else'. Raw residual data falls into theis category. ******************************** Training a codebook on the data: The trainer for each specific purpose is custom; lspvqtrain is used for LSP data, residuevqtrain for residue (not yet checked in; we're still playing with it :-). genericvqtrain is a generic trainer that trains based on a mean squared error. each trainer takes the same command line syntax (run with no args to see it): xxxxvqtrain basename [options] in...
