Speex dev - Feb 2006 - Help on Speex VBR mode

I have a work to do about the VBR mode of Speex and the way it works. I must
study the vbr.c file. I get the global idea about what the code does, but
I'm not able to describe it in details.

So I would like to know if there's somewhere a documentation about the
vbr.ccode that I could read to make me understand how it works ?

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.
