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.

You might think of abr as being the worst of both worlds. It is not able to vary its bitrate as much as vbr to adjust to the needs of the material, but it also is not exactly constant bitrate when the limitations of data transmission require it. It is also harder to seek within a file than with cbr, and some players don't do a good job of displaying the actual bitrate of a file in either abr or cbr.
