Title:
SIGNAL PROCESSING DEVICE, ACOUSTIC OUTPUT DEVICE, AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/189075
Kind Code:
A1
Abstract:
The present invention makes it difficult for a user to notice that frequency characteristics are being measured while shortening measurement time and mitigating user discomfort accompanying measurement when measuring frequency characteristics regarding a plurality of acoustic output drivers. A signal processing device according to the present disclosure comprises: an output control unit that causes an acoustic output driver to execute a plurality of instances of acoustic output with differing combinations of output frequency bands of a sound signal for a sound signal output to each of a plurality of acoustic output drivers disposed in an acoustic output device; a frequency analysis unit that performs frequency analysis regarding a collected sound signal for each of the plurality of instances of acoustic output and obtains the frequency characteristics of each of the plurality of instances of acoustic output; and a characteristic organization unit that organizes the frequency characteristics of each of the acoustic output drivers from the frequency characteristics of each instance of acoustic output obtained by the frequency analysis unit.
