摘要

Summary of spatial audio transmission apparatus; apparatus for spatial audio coding; the method of generation of spatial audio output signals; and a coding method of spatial audio codifiEr (501) generates data representing a set of audio for a first downmix and data that characterize the audio objects.In addition, a parameter of diffusion depends on the direction indicative of a degree of diffusion of a residual downmix is provided.Where the residual downmix corresponds to a downmix components of audio from the audio scene with the audio objects being extracted.An apparatus for transmission (503) comprises a receiver (701) which receives the data from the encoder (501).A circuit (703) generates signals to a speaker configuration space of the audio objects.A processor (709) generates sound signals does not diffuse to the configuration of the speaker space to apply a first processing the residual downmix and another processor (707) generates signals paFor the configuration of the speaker space to apply a second processing to the residual downmix to apply a descorrelau00e7u00e3o to downmix residual.The changes are dependent on the parameter dependent on the direction of diffusion. The signals are combined to generate an output signal. 1 / 1
