[vorbis] codebook training

[Dobler Ervin]

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 generated resaux_short.vqd and resaux_long.vqd files, trying different entries, dim and 
q_quant parameter values. However the result was the same: 
- the iteration did not converge, 
-the metric error was high (in the 1-10 range)
-the produced .vqi file contained some #IND values as biases.
-when I run VQBuild on the resulting .vqi files, it reported lots of duplicate entries, and removed.

Can anyone please tell me what could be wrong? Even better, can anyone show me some docs about training codebooks for Vorbis?
Thanks
Ervin Dobler
