Abstract
A sound field reproduction apparatus comprises a reflectional sound signal generating circuits for generating quasi-reflectional sound signals by summing a plurality of delay signals obtained by delaying source signals in order, and amplifiers for amplifying the level of quasi-reflectional sound signals. The apparatus is characterized by a signal selecting and repeating device for alternatively repeating either the quasi-reflectional sound signals and the source signals, or source signals different from the above-described source signals. With this feature, it becomes possible to reproduce source signals other than the source signals for use in the sound field reproduction.
