[Speex-dev] Help on Speex VBR mode

[Jean-Marc Valin]

There's no doc about vbr.c except the few comments in the code. The
general idea is that there are lots of heuristics (e.g. voiced sounds
need more bits, near-silence requires less, ...) that give a certain
number of "points" for the current frame. Based on this, I have a table
to convert from "points" to bit-rate for a given vbr quality setting.
That being said, the VBR code could definitely be improved.
