ACOUSTIC CHARACTERISTIC CORRECTION DEVICE

摘要

PURPOSE:To prevent excess correction or irrational correction in the device correcting the response characteristic of a reproduction system so that the response characteristic of the reproduction system is made coincident with the desired characteristic. CONSTITUTION:An arithmetic operation means 142 calculates a correction characteristic based on a set desired characteristic and a measured characteristic. Correction such as an upper lower limit restriction of a correction level or restriction of a correction frequency range or the like is applied to the correction characteristic as required based on the operation of the operator.
