Mppenc/mppdec 1.12 And Mppenc/mppdec 1.93d5

I've been using "--standard --ltq 30" with 1.10. It seems that "--standard --ltq 300" is the same thing with 1.12. The bitrate reductions with the new encoder are pretty significant as I'm seeing reductions in the 8-12% range. I assume that these reductions come from the new code, not any differences in my command line. Klemm must have a few tricks up his sleeve because 8-12% savings puts Musepack even further along the size-quality scale.

Actually, the old --ltq 3
  • model now maps to --ltq 4[xx]. --ltq 3[xx] is the Klemm model, whereas --ltq 4[xx] is the Klemm/Buschmnn mixed model. This explains the bitrate reduction I saw: the Klemm model is somewhat less sensitive than the Buschmann model. I'll use --ltq 400 to keep things consistent.
