PURPOSE:To provide an equalizer capable of obtaining the desired frequency characteristics correctly. CONSTITUTION:The desired frequency characteristics is inputted by a mouse 16. The inputted frequency characteristics is displayed on CRT 14. The impulse respose is determined by performing reverse FFT for this frequency characteristics. The convolution operation is performed for the digital data for the musical sound by this impulse response and the modification for the musical sound is performed. Thus, the desired frequency characteristics can be obtained easily and correctly. |
