MICRO PHONE SIGNAL PROCESSOR FOR SONG ACCOMPANIMENT

摘要

PURPOSE: A micro phone signal processor for song accompaniment is provided to decrease an additional amount of an echo in the case of adding only the echo by decreasing a mixing rate of an effect signal in a mixing unit. CONSTITUTION: An accompanying music generating circuit(10) receives musical piece data reproduced from a recording medium and generates a musical sound signal of an accompanying music. A dry muting circuit(12) passes a micro phone signal or stops the pass of the micro phone signal. An effect signal generating circuit(14) generates the effect signal of the micro phone signal. A mixing circuit(16) mixes the output signal of the dry muting circuit(12) and the output signal of the effect signal generating circuit(14). An echo signal generating circuit(20) receives an output signal of a mixing unit(42) and generates an echo signal.
