Comment(by toots):
Ok, I've had a review of the library's source code. The quality parameter
in Vorbis is confusing.
The library setting goes from -0.1 to 1.0 for Xiph and -0.2 to 1.0 for
aoTuV.
The encoding front-end uses a mapping from the interger to one of these
values. For instance, at 44.1 kHz for aoTuV, you have:
{{{
static const double quality_mapping_44[13]={
-.2,-.1,.0,.1,.2,.3,.4,.5,.6,.7,.8,.9,1.0
};
}}}
This does not fix the problem of checking the value but indicates that the
quality parameter for vorbis should be documented. I have already changed
the wikipedia page.
