Document Type and Number:
WIPO Patent Application WO/2021/024752
Kind Code:
A1
Abstract:
The present art pertains to a signal processing device, method, and program that are configured to reduce a signal throughput. The signal processing device comprises: a first convolution unit that performs convolution on an audio signal by using a differential filter for adding the characteristic of a difference between a transfer characteristic from a first position to a hearing position on a conical confusion circumference and a transfer characteristic from a second position to the hearing position on the circumference; and a notch formation unit that filters the signal obtained by the convolution by using a notch forming filter for forming a high frequency notch. The present art is applicable to signal processing devices.
