FUZZY SOUND QUALITY CONTROLLER

摘要

PURPOSE:To control sound quality by calculating a weight to a gain of each frequency band based on a membership function stored in a membership function storage device and a degree of sound quality inputted from a control input device so as to enter the degree of abstract expression. CONSTITUTION:The controller is provided with a sound quality control input device 1 entering the degree of sound quality in abstract expression and a membership function storage device 2 storing a membership function representing the gain distribution of the sound quality in abstract expression by the sound quality control input device 1. Then weighting calculation is implemented based on the membership function stored in the membership function storage device 2 and the degree of sound quality inputted by the sound quality control input device 1 and the gain of each frequency band is decided by a weight calculation device 3. Thus, the sound quality is controlled by inputting the degree of abstract expression.
