Abstract

An audio apparatus has a receiver (301) receiving a data signal including encoded data for a mono downmix audio signal and spatial upmix parameters for upmixing the downmix to a stereo signal. It further includes a directional circuit (305) estimating a directional signal of a signal model for a stereo signal, and a generator 317 generating two estimated signals being residual signals of the signal model. A rendering function (307, 309, 311, 313, 319) renders a stereo signal from the signal model. An adapter (321) controls the generator (317) to adapt a relative property, such as specifically a correlation or relative signal level, between the first estimated signal and the second estimated signal in dependence on the spatial upmix parameters.
