摘要： Binaural rendering a multi-channel audio signal into a binaural output signal (24) is described. The multi-channel audio signal comprises a stereo downmix signal (18) into which a plurality of audio signals are downmixed, and side information comprising a downmix information (DMG, DCLD) indicating, for each audio signal, to what extent the respective audio signal has been mixed into a first channel and a second channel of the stereo downmix signal (18), respectively, as well as object level information of the plurality of audio signals and inter-object cross correlation information describing similarities between pairs of audio signals of the plurality of audio signals. Based on a first rendering prescription, a preliminary binaural signal (54) is computed from the first and second channels of the stereo downmix signal (18). A decorrelated signal X d n , k is generated as an perceptual equivalent to a mono downmix (58) of the first and second channels of the stereo downmix signal (18) being, however, decorrelated to the mono downmix (58). Depending on a second rendering prescription P 2 1 , m , a corrective binaural signal (64) is computed from the decorrelated signal (62) and the preliminary binaural signal (54) is mixed with the corrective binaural signal (64) to obtain the binaural output signal (24).
