Hi AAC developers,

How do you split bitrate among channels in 5.1 configuration?

5.1 = front stereo pair + mono center + back stereo pair + subwoofer

For example:
256 kbps = ? + ? +? + ?


Thanks!
Danijel

I would hope that it is divided according to the difficulty of encoding each channel rather than in a fixed ratio. Also, it should take advantage of similarity of channels by encoding the sum and difference of pairs, etc.
