A signal processing device includes an excessive input estimating unit 102 that estimates excessive input of a target signal, a controller 105 that calculates frequency characteristics which will lessen the excessive input of the target signal from the excessive input information estimated by the excessive input estimating unit 102, and a frequency characteristic modification unit 103 that modifies the frequency characteristics of the target signal in accordance with the frequency characteristics the controller 105 calculates. |
