摘要： A spatial audio processing system and method including the steps of: dividing the series of virtual speakers into a series of horizontal planes around the expected listener; rendering the audio source to an intermediate spatial format for playback over a series of virtual speakers arranged in each of the series of planes around the listener, the rendering including: an initial panning of the spatialized virtual audio source to each of the horizontal planes to produce a plane rendered audio emission; a subsequent panning of each of the plane rendered audio emissions to a series of virtual speaker locations within each plane, with the subsequent panning utilizing a series of panning curves which are spatially smoothed to can include spatial frequency components which are less than the Nyquist sampling rate of the audio source.
