'lame' is an MP3 encoder. VBR is 'variable bitrate', which means that high-information sections in the input stream get more bits in the output bitstream, and low-information sections in the input stream get fewer bits in the output bitstream. An encoded song might use 192Kb/s for a few seconds, and then 32Kb/s for a second, and jump up to 256Kb/s for a quarter-second before dropping down to 128Kb/s--but still sound to your ear like it was encoded at a constant bitrate of 256Kb/s. All so that audio fidelity is maintained when there's something there to actually hear. Or, more simply: * 'lame' is an MP3 encoder * 'VBR' stands for 'variable bitrate', and offers a better size/quality tradeoff scale than saying "I want 192Kb/s" -- :wq
