Binaural rendering a multi-channel audio signal into a binaural
output signal is described. The multi-channel audio signal has a
stereo downmix signal into which a plurality of audio signals
are downmixed, and side information having a downmix
information, as well as object level information of the
plurality of audio signals and inter-object cross correlation
information. Based on a first rendering prescription, a
preliminary binaural signal is computed from the first and
second channels of the stereo downmix signal. A decorrelated
signal is generated as an perceptual equivalent to a mono
downmix of the first and second channels of the stereo downmix
signal being, however, decorrelated to the mono downmix.
Depending on a second rendering prescription, a corrective
binaural
