DEVICE FOR CORRECTING FREQUENCY CHARACTERISTIC OF SOUND FIELD

Title:

DEVICE FOR CORRECTING FREQUENCY CHARACTERISTIC OF SOUND FIELD

Document Type and Number:

WIPO Patent Application WO/1993/011647

Kind Code:

A1

Abstract:

A device for correcting transmission frequency characteristics, wherein when a synthesis frequency characteristic exceeds a predetermined level, the combination of parameters not exceeding the predetermined level can be known. This device for correcting transmission frequency characteristics according to preset parameters has a group of filters whose filter factors and filter characteristics are determined based on the parameters corresponding to their center frequencies, sharpnesses, and gains. The device is provided with an input section (1) for setting parameters for every filter, a means (5) for computing optimum parameters, and a control section (5). The means (5) computes optimum parameters of specified filters within the predetermined level when the synthesis frequency characteristic of the filter group based on the parameters set to the specified filters exceeds the predetermined one. The control section (5) displays the computed optimum parameters, and the frequency characteristics of the specified filters and the synthetic frequency characteristic of the filter group which are computed according to the computed optimum parameters.
