I hear a lot about CBR and VBR; what’s wrong with ABR?, Was “MP3 ABR WHY NOT.” (shouting won’t make anyone likelier to reply) |

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.

Also ABR / CBR is inferior to VBR in terms of pre-echo control. V5 can outdo ABR 170k in impulse handling. When using higher bitrate - 224 ~ 320k CBR / ABR converges so yes below that you could be getting the worst of everything. At high bitrate there might be an advantage: predictable size, max hardware compatibility, theoretical safety from aggressive VBR compression when psymodel is failing.
