I have read numerous forums and articles about mp3 cbr and vbr, some swear by cbr others vbr, the debate just goes on and on. I,ve tried cbr 256, vbr 256, cbr 320, cbr 192 cbr etc and I cant hear any difference. My question is why bother with cbr or vbr, why dont people just go with MP3 ABR, would this not be the ideal compromise, or I am missing something, as there does seem to be lack of mp3 abr on offer as downloads from the likes of Napster etc.

The main strength I've seen of ABR is the predictable file sizes while retaining somewhat better quality than CBR. For example, if I want to burn a data CD full of MP3s for my car, I can fairly easily calculate the bitrate to make the music I've selected fit onto one CD. I can either do multiple encodings with various -V settings until I find one that comes in under the size limit, or I can just use ABR and get it right the first time.

As pdq mentioned, a multi-pass mode would certainly make MP3 ABR a better proposition.
