ABR is average bitrate (current Vorbis mode looks mostly like ABR). In
ABR you set desired average bitrate, and encoder tries to acchieve it.

VBR is variable bitrate. You set quality, and encoder will encode the
track according to complexity. For example, in VBR, one track could
come out at average 120 kbps, while some other (with same quality
setting) at 190 kbps.
