Well, *I* didn't assume anything (though the last sentence could be
taken as if I did, I guess). >;-)

Regarding bitrate estimates: the nominal bitrate is (currently) filled
in as follows:

 0  - 64
 1  - 80
 2  - 96
 3  - 112
 4  - 128
 5  - 160
 6  - 192
 7  - 224
 8  - 256
 9  - 320
 10 - 498

Good enough for me.

Btw, did a quick test using applause.wav (available at the Lame site, I
think; "standard" test sample, AFAIK). At quality 4, there is an easily
heard "swashing" (a bit like maracas) sound that shouldn't be there. At
q 5, I didn't hear anything (didn't ABX, but at least there wasn't any
obvious fault).
