No, this is no thread about what actually sounds better (well, still kind of
), but more about the inner workings of cbr and vbr encoding.
I'm debating with a user on another forum, if 320cbr is the best setting for a MP3. I - and the wiki on hydrogenaudio
- think that it is, since it is the maximum sample rate that one is able to achive with MP3. He says, that v0 is better than 320cbr.
His argumentation about the working of mp3 goes like this: If you work with 320cbr you use 160kbps to save one channel, and the other 160kbps to save the difference between the other channel. But it will never be more than 160kbps per channel. So he says with VBR this restriction doesn't exist. So if the channels are pretty much the same it uses more than 160kbps for one channel, and the rest to encode the difference between the two.
In my understanding he's doing some mixup between vbr and joint stereo...
My question now is, how does the encoding in cbr or vbr really work? As far as i understand 320cbr would give you 160 per channel on every sample. Is vbr really able to give one channel more than 160kbps? And wouldn't joint stereo affect the two methods in the same way?
