Abstract:
An apparatus for upmixing a downmix audio signal describing one or more downmix audio channels into an upmixed audio signal describing a plurality of upmixed audio channels includes an upmixer and a parameter determinator. The upmixer is configured to apply temporally variable upmix parameters to upmix the downmix audio signal in order to obtain the upmixed audio signal, wherein the temporally variable upmix parameters include temporally variable smoothened phase values. The parameter determinator is configured to obtain one or more temporally smoothened upmix parameters for usage by the upmixer on the basis of a quantized upmix parameter input information. The parameter determinator is configured to combine a scaled version of a previous smoothened phase value with a scaled version of an input phase information using a phase change limitation algorithm, to determine a current smoothened phase value on the basis of the previous smoothened phase value and the phase input information.

Claim (Index 4):
The apparatus according to  claim 3 , wherein the parameter determinator is configured to select a basic phase combination rule, if the difference between the input phase information and the previous smoothened phase value is in a range between \u2212\u03c0 and +\u03c0, and to select one or more different phase adaptation combination rules otherwise;\n wherein the basic phase combination rule defines a linear combination, without a constant summand, of the scaled version of the input phase information and the scaled version of the previous smoothened phase value; and \n wherein the one or more phase adaptation combination rules define a linear combination, taking into account a constant phase adaptation summand, of the scaled version of the input phase information and the scaled version of the previous smoothened phase value.
