摘要： A parameter transformer generates level parameters, indicating an energy relation between a first and a second audio channel of a multi-channel audio signal associated to a multi-channel loudspeake configuration. The level parameter are generated based on object parameters for a plurality of audio objects associated to a down-mix channel, which is generated using object audio signals associated to the audio objects. The object parameters comprise an energy parameter indicating an energy of the object audio signal. To derive the coherence and the level parameters, a parameter generator is used, which combines the energy parameter and object rendering parameters, which depend on a desired rendering configuration.

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 (Xn,kd) 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 (P21,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).
