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 2):
The apparatus according to  claim 1 , wherein the parameter determinator is configured to combine the scaled version of the previous smoothened phase value with the scaled version of the input phase information, such that the current smoothened phase value is in a smaller angle region out a first angle region and a second angle region, wherein the first angle region extends, in a mathematically positive direction, from a first start direction defined by the previous smoothened phase value to a first end direction defined by the input phase information, and wherein the second angle region extends, in a mathematically positive direction, from a second start direction defined by the input phase information to a second end direction defined by the previous smoothened phase value.
