Abstract

PURPOSE:To give the feeling of spread to the reproduced sound, by adding the positive and negative phase components which are the signal difference of components of left and right singals contg. many reverberation components to the components of left and right signals. CONSTITUTION:The left and right audio signals are given to the terminals 1L and 1R. The left signal and the inverted right signal are fed to the addition circuit 3 to obtain the difference signal L-R contg. many reverberation components. The difference signal is fed to the addition circuit 6 and also fed to the addition circuit 8 via the inversion circuit 7. With this addition, the sound from the speakers 16, 17 can have the feeling of spread. Further, the difference signal L-R is fed also to the addition circuits 12, 13 via the HPF9, phase shift circuit 10 and inversion circuit 11, allowing to make the feeling of direction of sound unclear and to avoid the feeling of a closed room.
