Abstract

An audio apparatus generates a data signal including encoded data for the mono downmix audio signal being a downmix of a stereo signal, spatial upmix parameters, and data for a difference signal indicative of a difference between the mono downmix audio signal and a directional signal representing a point source audio component. Another apparatus comprises a receiver (301) receiving the data signal and a compensator (305) which generates a modified mono downmix audio signal by compensating the mono downmix audio signal as a function of the difference signal. The resulting modified mono downmix audio signal is rendered by a renderer (307) at a direction determined from the spatial upmix parameters by a direction determining circuit (309).
