PURPOSE:To generate a reverberation sound having a natural expanding sense by one reverberation sound generating circuit, by making a reverberation sound signal which has been synthesized and generated from right and left channel signals, branch into two giving a level difference to the other signal, to one signal, and applying these signals to the original channels, respectively. CONSTITUTION:L and R channel signals which have been inputted to input terminals 1, 2 are added by an adding circuit 3, and thereafter, inputted to a reverberation sound generating circuit 4, and a delay processing is applied and a reverberation sound signal is generated. An output of the circuit 4 is made to branch into two, and one of them is added to the original L channel signal by an adding circuit 6, and the other is attenuated by 6-9dB by an attenuator, and thereafter, added by an adding circuit 7 to the R channel signal in which a transfer time difference of a sound by right and left loudspeakers and a level difference have been compensated by a delaying circuit 10 and an attenuator 11. Output signals from the circuit 6, 7 are outputted from output terminals 8, 9. |
