I wonder why there isn't a 288kbps bitrate. There is just 256kbps and after that 320 kbps...I think this gap is quite big. Isn't that a waste of bits? I mean, let's say in a vbr mode, the encoder 'guesses' that it needs 270 kbps there is no way to use 256kbps and the reservoir to compensate the missing bits...so the encoder would have to use 320 kbps...but then, there is no way to store that many extra bits in the reservoir for the next frame.
Same thing for CBR modes. When mp3 was developed most people used CBR since no one could have guessed about LAME's 3.96.1 excellents --preset standard mode. And it's quite a size difference if I use CBR 256 or 320 kbps...especially back then...

The bitrate index located at frame headers is limited to 4 bits. That's why the format developers had to limit the amount of available bitrates.

Where would be the disadvantage? -------------------- --alt-presets are there for a reason! These other switches DO NOT work better than it, trust me on this.
