Abstract
An encoder () generates data representing an audio scene by a first downmix and data characterizing audio objects. In addition, a direction dependent diffuseness parameter indicative of a degree of diffuseness of a residual downmix is provided where the residual downmix corresponds to a downmix of audio components of the audio scene with the audio objects being extracted. A rendering apparatus () comprises a receiver () receiving the data from the encoder (). A circuit () generates signals for a spatial speaker configuration from the audio objects. A transformer () generates non-diffuse sound signals for the spatial speaker configuration by applying a first transformation to the residual downmix and another transformer () generates signals for the spatial speaker configuration by applying a second transformation to the residual downmix by applying a decorrelation to the residual downmix. The transformations are dependent on the direction dependent diffuseness parameter. The signals are combined to generate an output signal.
