Abstract

See full text

Disclosed in the invention is a virtual reproduction method for a multichannel spatial surround sound in three-dimensional space. Multichannel spatial surround sound signals are undergone a sum and difference operation and processed with virtual reproduction signal processing functions, then fed to four actual loudspeakers arranged at left-front-up and right-front-up directions on a high elevation plane of 30°±10° and horizontal left-front and right-front directions for reproduction, and generate a auditory effect of spatial surround sound. The invention simplifies the number and arrangement of loudspeakers required for multichannel spatial surround sound reproduction, and is suitable for cases in which the arrangement of multiple loudspeakers for spatial surround sound is infeasible, such as in a TV set, and so on.
