Abstract:
1. An audio rendering device which uses multichannel speakers, the device comprising: a first delay computation unit configured to compute, based on rendering information about the multichannel speakers, a first delay which is assigned to each of speakers included in the multichannel speakers and generates a primary wavefront which propagates in a predetermined traveling direction from a sound source that is each of the speakers; a second delay computation unit configured to compute, based on the rendering information about the multichannel speakers, a second delay which is assigned to each of the speakers and generates, on the primary wavefront, a secondary wavefront having a scattering wavefront; an addition unit configured to add up the first delay and the second delay to compute a total delay for each of the speakers; and a delay filter which applies the total delay to an input audio signal to generate a multichannel audio signal for use in rendering with the multichannel speakers, and outputs the multichannel audio signal to the multichannel speakers.
