<p>PROBLEM TO BE SOLVED: To appropriately reduce noise included in sound signals.SOLUTION: A signal processing device 100 comprises: a subtraction part 115; and a correction part 120. The subtraction part subtracts a prescribed signal from a first signal based on an acquired sound included in at least one part of prescribed noise in the sound signal, and further, a generation part generates a second signal to be added to the first signal subtracted by the subtraction part. The correction part corrects amplitude of at least one part of the first signal and the generated second signal.</p> |
