  # The following function gives you a weight w for each cc, where cc is the channel configuration written as a decimal number (1.0 for mono, 2.0 for stereo, 5.1 for surround, etc.):
  # w(cc) = cc^0.75
  # For 5.1 multichannel audio equivalent bitrate is 192 * w(5.1)/w(2.0) = 192 * (5.1/2.0)^0.75 = 387 kbps (~384 kbps)
