{HEAD ~ The purpose} of {TAIL ~ the invention} is to bridge the gap between parametric multi channel audio coding and matrixed surround multi channel coding by gradually improving the sound of an up mix signal while raising the bit rate consumed by the side information starting from 0 up to the bit rates of the parametric methods
