The parameters "-m j -V 4 -q 2 -lowpass 11 -b 64" and Lame version 3.98r are reported by mediainfo when I open a audiobook mp3 file I downloaded from e-music. Both mediainfo and mp3tag report this file as being a CBR file, but from reading the VBR documentation here http://lame.sourceforge.net/vbr.php using the -V option produces a VBR file even without the -v parameter and the -b parameter sets the minimum bit rate instead of forcing a constant bit rate. Is that correct or am I missing something? What would be the advantage of using -V 4 when encoding a CBR file?

-m j, V4 (when using only -v) are defaults (and -h equals to -q2).
I think it probably has to do with the Lame header, which stores a "quality" value and some related data (but not the switches themselves).
From there, part of the information can be obtained, but part of it might have no sense.
