2122268 9309643 PCTABS00022 A multi-channel sound simulation system for processing a stereophonic signal having a high frequency component for use with at least a pair of primary loudspeakers (13 and 14) and a pair of secondary loudspeakers (15 and 16) includes a receiving member (10) for receiving the stereophonic signal and for producing a first primary channel signal (LF and RF) and a second primary channel signal (LR and RR). The first and second primary channel signals (LF and RF) are adapted to be respectively applied to a first primary loudspeaker (13) and a second primary loudspeaker (14). The receiving member (10) is further adapted to divide the input signal into a first secondary channel signal (LR) and a second secondary channel signal (RR). The first and second secondary channel signals (LR and RR) are fed through a roll-off member (L1 and C1) which inhibits the high frequency component of the signal, thereby producing inhibited first and second secondary channel signals (LR and RR). These inhibited signals are adapted to be respectively applied to the first and second secondary loudspeakers (15 and 16) to supply ambiance information to a listener in a home audio/video system. The listener thus receives a fuller, more realistic sound in his/her own home.
