A signal processing apparatus includes at least one equalization section, each of the equalization section being capable of setting a center frequency, a gain value at the center frequency, and a Q value and allowing set frequency-amplitude characteristics to be applied to an input signal; and a computation section. The computation section performs a center frequency determination process for computing, for target characteristics of the equalization section, a difference from the target characteristics for each area divided by a frequency portion where the gain of the characteristics of the equalization section is small and a frequency portion where the gain of the characteristics of the equalization section is large, a gain value determination process for determining the gain value at the center frequency of the equalization section, and a Q value determination process for setting the determined center frequency and the determined gain value.
