The data for the bands (master/slave) assigned to left/right in an arbitrary way, and the coefficients can be negated afterwards. Encoding favours the same settings for all channels.

• One bit: 0 = master is left for all bands, otherwise
  • One bit: 0 = master is right for all bands, otherise
    • One bit per non-zero band: 0 = master=left, 1 = master=right
• One bit: 0 = don't negate coefficients of the right channel, otherwise
  • One bit: 0 = negate coefficients of the right channel for all bands, otherwise
    • One bit per non-zero band: 0 = don't negate, 1 = negate
