ACOUSTIC RENDERING DEVICE AND ACOUSTIC RENDERING METHOD |
摘要 |
An audio rendering device which uses multichannel speakers includes: a first delay computation unit (501) which computes, based on rendering information about the multichannel speakers, a first delay corresponding to a primary wavefront which propagates in a predetermined traveling direction from a sound source that is each of speakers included in the multichannel speakers; a second delay computation unit (502) which computes, based on the rendering information about the multichannel speakers, a second delay corresponding to a secondary wavefront which is generated by the primary wavefront and has a scattering wavefront; an addition unit (503) which adds up the first delay and the second delay to compute a total delay; and a delay filter (504) 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. |
