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 misunder...

...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 .v...

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 ? Where can I get these information? Thank you!
