Abstract
An audio spatial rendering apparatus and method are disclosed. In one embodiment, The audio spatial rendering apparatus includes a rendering unit for spatially rendering an audio stream so that the reproduced far-end sound is perceived by a listener as originating from at least one virtual spatial position, a real position obtaining unit for obtaining a real spatial position of a real sound source, a comparator for comparing the real spatial position with the at least one virtual spatial position; and an adjusting unit for, where the real spatial position is within a predetermined range around at least one virtual spatial position, or vice versa, adjusting the parameters of the rendering unit so that the at least one virtual spatial position is changed.

47. An audio spatial rendering method comprising:
-
obtaining at least one virtual spatial position from which a reproduced far-end sound to be spatially rendered from an audio stream is perceived by a listener as originating; obtaining a real spatial position of a real sound source; comparing the real spatial position with the at least one virtual spatial position; adjusting, where the real spatial position is within a predetermined range around the at least one virtual spatial position or vice versa, parameters for spatial rendering so that the at least one virtual spatial position is changed; and spatially rendering the audio stream based on the parameters as adjusted.

48. A computer-readable medium having computer program instructions recorded thereon, when being executed by a processor, the instructions enabling the processor to execute an audio spatial rendering method comprising:
-
obtaining at least one virtual spatial position from which a reproduced far-end sound to be spatially rendered from an audio stream is perceived by a listener as originating; obtaining a real spatial position of a real sound source; comparing the real spatial position with the at least one virtual spatial position; adjusting, where the real spatial position is within a predetermined range around the at least one virtual spatial position, parameters for spatial rendering so that the at least one virtual spatial position is changed; and spatially rendering the audio stream based on the parameters as adjusted.
