摘要：
A reproducing apparatus mixes the voice information from a microphone and the information reproduced from a recording medium in which a vocal signal plus an instrumental signal is contained as a first signal in a first channel and only an instrumental signal is contained as a second signal in a second channel. A first mixing circuit mixes the first signal and the second signal. The output of the first mixing circuit is mixed by a second mixing circuit with the voice information from the microphone. A control circuit or audio detecting circuit provides a control signal in accordance with the level of the voice information from the microphone. The control signal controls a selection control circuit to gradually and smoothly vary the mixing ratio of the first signal and the second signal when mixing these two signals.
