Abstract

An audio apparatus comprises a first renderer (205) applying a directional rendering to a mono downmix with the rendering being based on a channel transfer function retrieved from a store (211) storing transfer functions for different directions. The rendering is for a direction determined in response to spatial upmix parameters provided for the downmix by a direction determining circuit (209). A second intermediate stereo signal may be rendered from a decorrelated version of the mono downmix by a second renderer (217) using a predetermined rendering, such as for example from a specific direction/position that is not signal dependent. A combiner (219) generates an output stereo signal by combining the intermediate stereo signals. An adapter (221) adapts the level of the first intermediate stereo signal relative to the level of the second intermediate stereo signal in the output stereo signal dependent on a first scaling value determined from the spatial parameters.
