Abstract

As a desired digital signal processor (DSP) mode is selected from DSP setting buttons displayed in a DSP setting window, only those slide bars for changing parameters of the selected DSP mode are displayed. As a slider bar corresponding to a parameter to be changed is selected from the slide bars displayed in the DSP setting window, an area of an impulse response diagram to be influenced by a change in the parameter value is indicated in a discriminatory manner by an arrow or the like. A user can visually confirm the acoustic effect to be changed by the value of each DSP parameter and can change the parameter value with ease.
