发明名称 SURROUND SOUND EFFECT CONTROL DEVICE
摘要 A surround sound effect control device includes a plurality of sound signal sources each for producing a sound signal. A sound source selection signal generator produces a sound source selection signal indicative of one sound source. A plurality of surround effect circuits are provided for modifying the sound signal.
