The quality criterion can be derived with respect to {HEAD ~ a resulting total bit rate} of the parametric representation 112 or with respect to quality aspects, taking into account the perceptual quality of {TAIL ~ a reproduction} of the multi channel signal 106 based on the parametric representation 112
