1. A signal processing device comprising:
processing circuitry configured to:
receive an input of extraction target information indicating which audio class of an audio signal is to be extracted from a mixture audio signal constituted by a mixture of audio signals of a plurality of audio classes;
integrate information of the mixture audio signal and the extraction target information; and
output a result of extracting the audio signal of the audio class indicated by the extraction target information from the mixture audio signal with a neural network by using a result of the integration of the information of the mixture audio signal and the extraction target information.
