.vqd example?
...ntlist, 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 latticebuild to get a first try .vqh file
Any comments about what's allowed and how to choose addmul?
Then I tried latticetune .vqh-file .vqd-file
ohoh tha name had to be precisely latticetune (or restune?)
ok I tried restune to read multiple cols. from lsp0coeff_0.vqd
still not a big difference. Tried changing values in my .vql
file. This made some difference. but I can't figure it out.
How does one choose reaso...

what script or command makes the codebooks? (fwd)
...targets to my Makefile.am
to build with -DTRAIN_LSP and/or -DTRAIN_RES (and/or -DTRAIN_RESENT,
if that's more what you need).

You'll probably need to change some code in latticetune.c for this to work.
(I had to: the q_sequencep treatment was a bit off, and you don't
interleave that data).

Here I mucked with vorbisenc.c to add a new mode with a certain
bit-rate window.

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
