PURPOSE:To obtain excellent stereoscopic sense by adjusting the level of right/ left signals collected at two positions separately, mixing the retarded signal in crossing with the signal before processing, controlling the level and supplying the result to right/left earphones. CONSTITUTION:Right and left signals R, L collected by microphones provided to two positions are outputted from a reproducing means 1. The level of the signal L is controlled by a level control means 2, the signal is retarded by a delay means 4 to obtain a signal L'. Similarly, the level of the signal R is controlled (3), retarded (5) to obtain the signal R', mixing means 6, 7 mix the signals L, R' and R, L' to control (8, 9) the level and the result is fed to left, right earphones 10, 11. Thus, the excellent stereoscopic sense equal to the case with that of the speaker is obtained. |
