Title:
SIGNAL PROCESSING DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/085117
Kind Code:
A1
Abstract:
The present invention pertains to a signal processing device, method, and program, configured so that it is possible to achieve spatial noise cancelling using reduced space and a low computation quantity. A signal processing device comprises a control unit that: generates, on the basis of a first microphone signal obtained by collecting sound with a first microphone array comprising a plurality of microphones, a speaker drive signal for an output sound to cancel sound collected by the first microphone array, the sound being propagated from outside a prescribed area to the prescribed area; and outputs an output sound from a speaker array comprising at least one high-order speaker, on the basis of the speaker drive signal. The present invention is applicable to a signal processing device.
