Hi! Now I am confused by the concept of VBR and ABR. I think the ABR is just one kind of VBR which has the upper and lower limit, is it right? When using the ogg vorbis encoder with a quality parameter, does it refer to VBR or ABR? Looking forward to your letter! ????????Lisa(^_^) ????????fangchao_dlut@sina.com ??????????2005-10-12
