Abstract
A signal processor includes an input unit that receives a first audio signal and a second audio signal including mutually correlated components, a delay unit that delays the first audio signal received at the input unit by a prescribed delay time, a synthesis unit that synthesizes the first audio signal having been delayed by the delay unit with the second audio signal received at the input unit, and outputs a third audio signal resulting from synthesis, and a frequency band restriction unit that restricts a level of the first audio signal before the synthesis in a prescribed frequency band including a frequency of a dip occurring at a lowest frequency among a plurality of dips occurring in a frequency characteristic of the third audio signal as a result of the synthesis performed by the synthesis unit.
