...t that I haven't yet done enough myself to be convinvced I changed it correctly enough. (I recommend you tune them without cutting them down in size, if you want to use latticepare. I use rather large training sets, so I asked my scripts to zero all the never-used entries for me.) > > Huffbuild to produce, aux book. Works fine. > > Latticehint the books. Works fine. (I think I rewired some of the vq code to use the lib/ search versions, which actually do fall back to a brute-force search. This is nicer than the vq/ version, which will fail, at least for some programs, because bru...

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

...w as well, as long as the flr[] is reasonably smooth (in the high freq region). This should help low bitrates. And, of course, the quantization control magic. Never thought 69kbps would sound that good. Still need some VQ training; I just can't figure how to use the tools correctly (currently, huffbuild is segfaulting on me). Yoho yoho! And off you go!
