Abstract: An apparatus is provided for controlling a graphic equalizer which is implemented by digital filters, each being assignable to a frequency band for regulating a level of the frequency band. In the apparatus, a set of control devices are provided in correspondence to respective frequency bands, each control device being operable to specify the level of the corresponding frequency band to either of a reference level or other level than the reference level. An assignment section operates when a number of the digital filters is less than a total number of the frequency bands, for assigning the digital filters to the frequency bands which are specified with the levels other than the reference level. A control section controls remaining digital filters which are not assigned to any of the frequency bands in a through state. A disabling section operates when the assignment section assigns all of the digital filters to the frequency bands which are specified with levels other than the reference level, for disabling operation of a control device which currently specifies the reference level.

Abstract: PROBLEM TO BE SOLVED: To provide a graphic equalizer control unit which acts a digital filter efficiently. SOLUTION: A controller 4 of a graphic equalizer splits filters of total 31 in a signal processing part 2 in a mode 2, and two graphic equalizers GEQ1 and GEQ2 are made to create as filters 21 1 -21 15 , filters 21 16 -21 31 . The number 15 of the digital filter is made fewer than the total 31 of bands. The controller 4 assigns 15 digital filters each dynamically band with which a level other than a reference level is directed by fader operating elements 14 1 -14 31 . The controller 4 makes to create one graphic equalizer GEQ1 to 31 digital filters 21 1 -21 31 in the signal processing part 2 in the mode 1. COPYRIGHT: (C)2006,JPO&NCIPI
