Abstract: Audio signal processing that satisfies both sound quality and cost is enabled.
A processing unit that performs processing based on an output audio signal of a first microphone unit focusing on sound quality and an output audio signal of a second microphone unit focusing on cost is included. For example, the processing performed by the processing unit includes processing of obtaining a beamforming output and processing of obtaining a sound source separation output. Furthermore, for example, the processing performed by the processing unit may include processing of generating a first audio signal on the basis of an output audio signal of the first microphone and processing of generating a second audio signal on the basis of output audio signals of a plurality of the second microphone units.
