Title:
SIGNAL PROCESSOR AND SIGNAL PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2017216614
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a signal processor and a signal processing method which reduce both coloration caused by a transmission system in an acoustic space, and coloration caused by signal processing.SOLUTION: The controller 30 of a sound field supporting system includes an acquisition unit 151 for acquiring an impulse response in a semi-open state where at least one acoustic feedback system is open, and at least one acoustic feedback system is closing, out of multiple acoustic feedback systems for one system becoming a measurement object, by controlling a microphone assignment unit 22, and a calculation unit 152 for calculating a gain correction amount, i.e., parameters of an EQ24, based on an impulse response acquired by the acquisition unit 151, and outputting the calculated gain correction amount.SELECTED DRAWING: Figure 6
