...outines that needs optimizing. If I understand _why_ it works, maybe I can optimize it to something different, that performs just as good in sound quality, and better in execution time. A second question: is there a standard way (like, executing some obscure program in the vq/ directory) to create _cascading_ codebooks? (I only need additive codebooks, not multiplicative ones). And is it possible to have the second-level and third-level etc. codebooks a different grouping-length than the first-level ones? Oh, and I want a _perfect_ 40kbps mode before the end of the year ;-) Cheers, Segher --- >8...
