Abstract

An audio apparatus renders a stereo signal and comprises a weight processor (105) determining frequency subband downmix weights from spatial parameters for the stereo signal. A downmixer (107) determines a mono downmix by downmixing the stereo signal using the downmix weights. A residual circuit (109) arranged to generate at least a first residual signal from a first channel of the stereo signal by generating frequency subband residual weights from the downmix weights, generating frequency subband compensation values downmix and the residual weights; and generating frequency subband values of the residual signal by compensation of the channel by the compensation values. A renderer (111) renders an output stereo signal by a directional rendering of the downmix to generate a first intermediate stereo signal and a second rendering of the residual signals to generate a second intermediate stereo signal with the output stereo signal being generated by combining the intermediate stereo signals.
