Abstract

PURPOSE:To make it possible to find easily a proper editing point, for example, a cutout point or a fade-out point, by reading coded music signal data, which is stored in a memory, and by performing the signal processing for this data. CONSTITUTION:The cutout operation example is described below. Ac is the address of memory 1 corresponding to the cutout point of the signal. Digital signal multiplier 2 multiplies coefficient from coefficient memory 9 and outputs the result to output terminal 5 for the output signal of memory 1 from start address Ao to address Ac at the cutout point and multiplies coefficient from coefficient memory 9 and outputs the result to output terminal 5 for the output signal from cutout point Ac to end address Ae. Consequently, the digital signal is cut out well at address Ac determined as the cutout point. The address value of the cutout point can be set arbitrarily by controller 10.
