Sound quality control system

摘要

A sound quality control system according to the present invention precisely and swiftly realizes a sound quality that is desired by a listener, by controlling sound quality based on quantitative counter model between the psychological characteristic and the physical characteristic of a sound reproduction apparatus. In a model constituting means, quantitative counter model between the physical characteristic of a sound reproduction apparatus and a plurality of the psychological quantity upon listening a sound therefrom is constituted for each respective psychological quantity. Based on the quantitative counter model, a desired sound quality is inputted to a compensation characteristics extracting means, and a compensation characteristic that realizes the desired sound quality is extracted. The compensation characteristic is set to a signal processing means; and an audio signal inputted in an audio signal input means is processed according to the compensation characteristic, and amplified to be reproduced by a loudspeaker. <IMAGE>
