'KARAOKE' (RECORDED ORCHESTRAL ACCOMPANIMENT) PLAYER

摘要

PURPOSE:To reproduce a sound field which is closed to live performance even in a general room by radiating a reverberation signal, generated according to an input sound signal, from a speaker different from a speaker for reproducing a singing voice and an accompaniment sound. CONSTITUTION:Musical sound source signals from a reproducing equipment group 1 which reproduces an orchestral accompaniment sound are applied to a mixing amplifier 4 through an amplifier 2 and a variable resistance attenuator 3. A singing voice signal collected by a microphone 5 is branched through an amplifier 6 and a variable resistance attenuator 7 and applied to the mixing amplifier 4 and a reverberation processing circuit 8. The accompaniment signals and singing voice signal which are adjusted in level properly by the variable resistance attenuators 3 and 7 are mixed by the mixing amplifier 15 and radiated from a speaker 12. Then the respective signals are adjusted by variable resistance attenuators 18 and 19 to a level matching a reverberation sound and mixed by a mixing amplifier 16. Then the mixed signal is converted by a reverberation processing circuit 8 into a reverberation sound, which is radiated from a speaker group 14.
