PURPOSE:To exactly set an equalizer to a desired frequency characteristic in a short time, and to easily attain the fine adjustment of the frequency characteristic. CONSTITUTION:A CPU 36 displays a frequency characteristic curve 44 in a prescribed shape on a window 42 of a display part 40 whose horizontal direction is used as a frequency axis, and whose vertical direction is used as a gain axis. At the time of operating a marker 48 of the characteristic curve 44 by an operating part 38, and moving it to the horizontal direction, the CPU 36 moves the characteristic curve 44 also to the horizontal direction, and supplies a parameter as the frequency characteristic according to the movement to a DSP 32. At the time of operating a marker 46 of the characteristic curve 44, and moving it to the vertical direction, the CPU 36 changes the display of the peak gain of the frequency characteristic curve 44, and supplies the parameter as the frequency characteristic according to the change to the DSP 32. At the time of operating a marker 50 of the frequency characteristic curve 44 by the operating part 38, and moving it to the horizontal direction, the CPU 36 changes the display of the inclination of the characteristic curve 44, and supplies the parameter as the frequency characteristic according to the change to the DSP 32. |
