Ｍ、右メイン信号ＲＭ、左サラウンド信号ＬＳ、
右サラウンド信号ＲＳを合成するようにした構成
において、上記左右メイン信号ＬＭ、ＲＭ、左右
サラウンド信号ＬＳ、ＲＳが、 ＬＭ＝Ｌ＋（Ｌ−△Ｒ）（φ） ＲＭ＝Ｒ＋（Ｒ−△Ｌ）（φ） ＬＳ＝（Ｌ−▽Ｒ）（φ−α） ＲＳ＝（Ｒ−▽Ｌ）（φ−α） ただし、△、▽は定数、φ、αは移相量で、α
＝４５〜９０゜ であることを特徴とする音場再生装置。[Scope of claim for utility model registration] For stereo signals L and R, left main signal L
M, right main signal RM, left surround signal LS,
In the configuration in which the right surround signal RS is synthesized, the left and right main signals LM and RM and the left and right surround signals LS and RS are as follows: LM=L+(L-△R)(φ) RM=R+(R-△L) (φ) LS=(L-▽R)(φ-α) RS=(R-▽L)(φ-α) However, △ and ▽ are constants, φ and α are phase shift amounts, and α
=45 to 90 degrees.
