To efficiently remove a signal including a highly independent sound source from a mixed signal.
A sound processing device 100 includes: a nonlinear processing part 102 that outputs a plurality of sound signals including sound sources existing in predetermined areas by performing a nonlinear process for a plurality of observed signals that are generated by a plurality of sound sources and are observed by a plurality of sensors; a signal selecting part 104 that selects a sound signal including a specific sound source from among the plurality of sound signals output by the nonlinear processing part and the observed signal including the plurality of sound sources; and a sound separating part 106 that separates a sound signal including the specific sound source that is selected by the signal selecting part from the observed signal selected by the signal selecting part.
