PROBLEM TO BE SOLVED: To provide a sound processing apparatus capable of suppressing a non-target sound while effectively suppressing musical noise. SOLUTION: A sound source separation part 24 extracts a component CA of a target sound frequency FA and a component CB of a non-target sound frequency FB with respect to respective frames made by sorting sound signals S1 and S2 in which the target sound and the non-target sound are mixed, on the time axis. A flattening part 34 flattens the intensity LB of the component CB of the non-target sound frequency FB over a plurality of frames. A synthesizing part 42 arrays the component CA of the target sound frequency FA and the component CB of the non-target sound frequency FB after being flattened by means of the flattening part 34 on the frequency axis.
